Spex Speaks Science

In this podcast, Spex is joined by Robert Thomas to discuss the cannabis testing industry and the challenges for inorganic testing of cannabis. Robert (Rob) Thomas is the principal of Scientific Solutions, an educational consulting company that serves the needs of the trace ele­ment user community. He has worked in the field of atomic and mass spectroscopy for almost 50 years, including 24 years for a manufacturer of atomic spectroscopic instrumentation. He has served on the American Chemical Society (ACS) Committee on Analytical Reagents (CAR) for the past 20 years as leader of the plasma spectrochemistry, heavy metals task force, where he has worked very closely with the United States Pharmacopeia (USP) to align ACS heavy metal testing procedures with pharmaceutical guidelines. Rob has written over 100 technical publications, including a 15-part tutorial series on ICP-MS. He is also the editor and frequent contributor of the Atomic Perspectives column in Spectroscopy magazine, as well as serving on the editorial advisory board of Analytical Cannabis. In addition, Rob has authored 5 textbooks on the fundamental principles and applications of ICP-MS. His most recent book is a new paperback version of Measuring Heavy Metal Contaminants in Cannabis and Hemp published in December, 2021. Rob has an advanced degree in analytical chemistry from the University of Wales, UK, and is also a Fellow of the Royal Society of Chemistry (FRSC) and a Chartered Chemist (CChem). Hosted by Patricia Atkins, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInLike this episode?

Mold and Fungi ubiquitous in the world and a persistent and dangerous contaminant for many agricultural products. Their size and spore mobility causes fungi to spread through agricultural products quickly when the environmental conditions are favorable.In this podcast, learn how significant crop losses and foodborne illness can be attributed mold and fungi when secondary metabolites called mycotoxins develop. Spex now offers the five most common mycotoxins in one easy to use standard for your analytical testing needs.Hosted by Patricia Atkins, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInLike this episode?

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 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.Hosted by Patricia Atkins, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInLike this episode?

Water is one of the most important chemicals and commodities in the world. Billions of people worldwide do not have access to clean drinking water traveling long distances to use substandard polluted water sources. Even in the United States, the majority of states have issues meeting water quality standards. In the rise of concerns of municipal water, bottle water has taken on an important role in hydration and the economy.In this podcast, we look at drinking water, bottled water and water sources in celebration of National Hydration Day!Our Spex drinking water standards are a part of safe water quality analysis worldwide. You can shop our drink water standards here.Hosted by Patricia Atkins, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInLike this episode?

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 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.Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInLike this episode?
