In this podcast, Patricia Atkins is joined with Spex Chemist Brij Tonk. Patricia and Brij touch on how Spex has grown over the years and the basics behind wet chemistry.Analytical Chemistry is the study of chemical composition, structure and behavior of matter by separating, identifying (qualitative analysis) and quantifying (quantitative analysis) matter using instruments, chemical and physical methods.  Analytical chemistry consists of classical methods (i.e. wet chemical methods) and instrumental methods (i.e. spectrometry, chromatography etc.). Wet chemistry or classical analysis are forms of analytical chemistry that use proven historical (classical) methods to determine the identity, amount or form of an analyte or element using wet techniques. Wet chemistry is sometimes called bench chemistry since many methods or assays occur at the laboratory bench and use laboratory glassware or plastic-ware.  In classical methods, identification can be based on differences in physical properties (i.e. color, melting point, boiling point etc.). Instrumental methods rely on the calculation of an analyte against a standard of a chemical or physical parameter (i.e. elemental spectra, uv absorption, mass determination etc.).Over the past few decades, many classical analyses have incorporated an automated or instrumental component (pH meters, automatic titrators, density meters etc.)  that blur the divide between classical methods and instrumental analysis. Many simple instruments are still considered to be part of classical analysis.Wet chemistry methods are grouped into qualitative and quantitative methods. Qualitative methods determine the identity or presence of compounds, functional groups or elements using changes in a physical or chemical parameter which cannot be measured. These changes include color, smell, physical state or appearance.  Examples of qualitative wet chemistry include flame tests and other chemical tests such as:  Hoffman's test etc. Quantitative methods determine the amount or concentration of a target by calculating the physical or chemical changes observed in qualitative methods.  These methods often use simple probes such as pH meters or measured titration to calculate a value.Hosted by Patricia Atkins, Senior Applications Scientist from SpexStay connected with Spex! Certified Reference Materials: https://www.spexcertiprep.com/Sample Preparation Equipment: https://www.spexsampleprep.com/Twitter: https://twitter.com/SpexScienceYouTube: https://www.youtube.com/user/SPEXCertiPrepYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Blog: https://www.spexsampleprep.com/blogs.aspxInstagram: https://www.instagram.com/spexscienceLinkedIn: https://www.linkedin.com/company/spexscience Support the show (http://www.spexcertiprep.com)

Accuracy in analytical testing starts at the very beginning with sampling and sample preparation prior to testing. If sample collection processes are flawed, then the final answers will be biased. The basis of accuracy of sampling and testing often rests on two inter-related and fundamental concepts: representative samples and homogeneity. Representative samples are selected to accurately reflect the larger group and should represent the characteristics of the group. Ideally representative samples are homogeneous or similar in nature but when that is not possible the best attempts must be made to achieve samples which represent most of the characteristics of the larger grouping.In the approaches to sampling agricultural crops such as cannabis, there are many factors which can influence and create bias in sampling. The type and area of sampling can dramatically change the results. Environmental factors, climate, sunlight, exposure to chemicals both intentionally and unintentionally can alter results for a host of target compounds from mycotoxins to cannabinoids. In this podcast, we will look at the traditional methods of agricultural sampling and how different target compounds found in cannabis products can be influence by growing practices, environmental factors and choice & timing of sampling.Hosted by Patricia Atkins from SPEX CertiPrepStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexcompaniesStay connected with SPEX SamplePrep!Website: https://www.spexsampleprep.com/Facebook: https://www.facebook.com/SPEXSamplePrep/Twitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexcompaniesSupport the show (http://www.spexcertiprep.com)

Speciation is defined as: ‘the distribution of an element amongst defined chemical species in a system’ (IUPAC). Chemical species include isotopic composition, electronic or oxidation states and molecular structures. Speciation analysis is the analytical process of identifying and/or measuring the amounts of one or more individual chemical species in a sample.Chemical and elemental species are important in many fields of science and health. Human health and nutrition can be influenced by the presence or absence of certain chemical species such as iron, selenium, arsenic, and mercury. Some chemical species are potentially toxic and are targets of concern. In this presentation, learn about the importance and role of chemical species.Hosted by Patricia Atkins from SPEX CertiPrep.Stay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexcertiprep/Stay connected with SPEX SamplePrep!Website: https://www.spexsampleprep.com/Facebook: https://www.facebook.com/SPEXSamplePrep/Twitter: https://twitter.com/SPEXCompaniesYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcompanies/LinkedIn: https://www.linkedin.com/company/spexsampleprep/Support the show (http://www.spexcertiprep.com)

In this episode of SPEX Speaks Science we discuss Terpenes and Flavonoids. Terpenes are the common term for a large group of compounds that contribute to flavor and smell of botanical products.

When Laboratories receive material for testing, it is often not in a state where it can be directly tested. It requires sample preparation techniques to expose or make possible the extraction of the desired analytes. For many samples, this can be a difficult process as their composition and physical properties make it hard to grind/mill/crush or otherwise reduce particle size and expose surface area. In this podcast, Patti and Tristan introduce the equipment and techniques for cryogenic grinding applications and discuss the fundamentals, methodology and versatility of the SPEX SamplePrep Freezer/Mill.Hosted by Patricia Atkins of SPEX CertiPrep and Tristan DeBona of SPEX SamplePrep.View SPEX SamplePrep's Freezer/MillStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCertiPrepYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcertiprep/LinkedIn: https://www.linkedin.com/company/spexcertiprep/Stay connected with SPEX SamplePrep!Website: https://www.spexsampleprep.com/Facebook: https://www.facebook.com/SPEXSamplePrep/Twitter: https://twitter.com/spexsampleprepYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexsampleprep/LinkedIn: https://www.linkedin.com/company/spexsampleprep/Support the show (http://www.spexcertiprep.com)

As businesses begin to return to operation, laboratories which may have been forced to shut down during the pandemic, are now being asked to reopen with a new level of concern for not only chemical contamination but viral contamination. During this time of heightened anxiety, it is good to know most common laboratory procedures used to keep scientists safe from chemical exposures also work well for limiting biological exposures. It is important to keep in mind all of the advice given by governmental agencies for our protection, but also develop a plan and set of resources to return to business in the office and in the laboratory.Hosted by Patricia Atkins and Rebekah Biermann of SPEX CertiPrep.View Back to the Bench: A Chemist's Guide to Returning to the LaboratoryStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCertiPrepYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcertiprep/LinkedIn: https://www.linkedin.com/company/spexcertiprep/Stay connected with SPEX SamplePrep!Website: https://www.spexsampleprep.com/Facebook: https://www.facebook.com/SPEXSamplePrep/Twitter: https://twitter.com/spexsampleprepYouTube: https://www.youtube.com/user/sampleprepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexsampleprep/LinkedIn: https://www.linkedin.com/company/spexsampleprep/Support the show (http://www.spexcertiprep.com)

Heavy metal exposure in the environment has led to toxic elements transitioning into our food and water supplies increasing human exposure. Agricultural products can be highly prone to heavy metal deposition and accumulation through repeated exposure to natural and contaminated environmental sources. In some cases, heavy metals are intentionally introduced to products as adulterants or to counterfeit high value commodities. The value of these commodities make them prone to adulteration and duplication. The consumption of botanical products has increased over the past two decades as consumers trend to what are perceived to be natural and high quality botanical products. The primary regions of spice and tea production around the world have often been cited as having less stringent safety and quality standards in regards to consumer products. Products from these regions have been noted to contain a variety of adulterants and contaminants including wear metals and toxic elements. This study will show examples of several types of products which may accumulate heavy metals including spices, hemp and other nutraceuticals.Hosted by Patricia Atkins, Senior Applications ScientistStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCertiPrepYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcertiprep/Support the show (http://www.spexcertiprep.com)

On a daily basis, the average person around the world is subjected to doses of heavy metals from a variety of sources. One of the most insidious sources of routes of exposure is through the food supply. The World Health Organization contends that food may be the source of the largest contribution to the intake of heavy metals (especially lead). Many foods may naturally contain heavy metal compounds, from either natural biochemical processes or from bio accumulation from the environment. Other foods and beverages become contaminated by natural, agricultural or industrial sources of heavy metals. Finally, there are food and beverage products which are intentionally adulterated or counterfeited with materials containing heavy metals. In this podcast, we will look at different sources of potential heavy metal exposure and their concentrations in a variety of food products including fish, and beverages. In addition to the original research presented, we will compare other historical studies and public health findings to showcase the sources and concentrations of various heavy metals found in the food and water supply in order to build a more complete picture of heavy metal exposure through food and beverages.Hosted by Patricia Atkins, Senior Applications ScientistStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCertiPrepYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcertiprep/Support the show (http://www.spexcertiprep.com)

It has only been in the last century that the contributions of women in science, engineering, technology and mathematics have been recognized. The first Nobel prize awarded to woman occurred in 1903. For hundreds of years women have contributed to science without the same accolades and laurels given their male counterparts. In this podcast, we will take a look at some of the historical women in science and take a closer look at their lives and discoveries.Hosted by Patricia Atkins, Senior Applications ScientistStay connected with SPEX CertiPrep!Website: https://www.spexcertiprep.com/Facebook: https://www.facebook.com/spexcertiprepTwitter: https://twitter.com/SPEXCertiPrepYouTube: https://www.youtube.com/user/SPEXCertiPrepBlog: https://spexcertiprepblog.wordpress.com/Instagram: https://www.instagram.com/spexcertiprep/Support the show (http://www.spexcertiprep.com)
