Wet Chemistry

Wet Chemistry

2021-07-1926:02

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 EquipmentYouTubeInstagramLinkedInSupport the show

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 EquipmentYouTubeInstagramLinkedInSupport the show

2020-06-1136:06

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.View Back to the Bench: A Chemist's Guide to Returning to the LaboratoryHosted by Patricia Atkins and Rebekah Biermann of SpexStay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInSupport the show

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.In this podcast we will explain several types of products which may accumulate heavy metals including spices, hemp and other nutraceuticals.Hosted by Patricia Atkins, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInSupport the show
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.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, Spex's Senior Applications Scientist Stay connected with Spex using the links below! Certified Reference MaterialsSample Preparation EquipmentYouTubeInstagramLinkedInSupport the show
