Speciation

Speciation

2020-10-1314:11

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. Flavonoids are botanical compounds, similar to terpenes, responsible for different processes for defense and metabolic processes in plants. These compounds are responsible for many colors observed in botanical materials and plants.Hosted by Patricia Atkins and Jeff Akers 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)
A normal part of laboratory operations is the use of personal protective equipment (PPE). Most laboratory personnel are familiar with common PPE such as gloves, safety glasses and lab coats. Now in the time of the pandemic laboratories are reassessing and adding to their PPE protocols with the addition of face masks, face shields and further protections. This podcast discusses the wide spectrum of disinfectants, sanitizers and additional PPE we are all adding to our laboratory operations.Hosted by Patricia Atkins of SPEX CertiPrep.View our PPE productsStay 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)
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)

Ten years ago, SPEX CertiPrep published a well-received study about the toxic elements in Pet Food. We found that some dog and cat foods were full of heavy metals. Since that study was done, the US government enacted the Food Safety Modernization Act (FSMA) which includes pet foods. Now, ten years later, we are getting ready to repeat our study to see what may have changed in pet foods over the last decade.Hosted by Patricia Atkins, Senior Applications ScientistOriginal Trace Metals Analysis in Commercial Foods Webinar: https://www.spexcertiprep.com/webinar/trace-metals-analysis-of-commercial-pet-foodStay 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)

The chemistry of color is actually a representation of the physical properties of chemicals that come through absorption of energy. The colors we see are a function of the light and energy absorbed and reflected by the materials and substances we observe. The chemistry of color is part organic chemistry, part physics known as spectroscopy. Join us as we look at the basics of the chemistry of color.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)
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)
