Spex Speaks Science

SPEX Speak Science dives into the world of vaping. In this episode we touch on the history and basics of vaping, the alarming news headlines, and most importantly the chemistry of vaping. Is vaping a safer alternative to smoking? Are the e-juices safe? Does the device itself effect the safety? Time will tell for this growing and changing industry.

Hosted by John Marotta, International Accounts Manager and Rebekah Biermann, Territory Manager

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.

This podcast provides insight and addresses the challenges in the testing and regulations surrounding hemp. With the recent passage of the Farm Bill, and subsequent federal acceptance of hemp as a legal crop, a new wave of agriculture, consumer and commercial products has sprouted virtually overnight. This new market has yet to see regulation at the federal level and this podcast will address some of the questions regarding testing, sample preparation and regulatory issues that we have observed from state to state. Stay tuned as we will continue to update you as the industry grows and matures.

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.

In this podcast, we look at the basics of the chemistry of color.

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.

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.

Human beings perceive the world through their five senses.  Two of the most important senses are taste and smell, both of which are based on chemical processes and reactions.

In this podcast, we will take a look at the chemistry of flavor and fragrance and how those chemical reactions equate to familiar tastes and scents.
