Analytical Cannabis 

Speaking at an Analytical Cannabis webinar in January 2022, Kim Ross, PhD, Chief Science Officer at Peak Compliance LLC, presented her talk on hemp regulation, testing and standardization.

Abstract: In the 21st century we've witnessed a rapid resurgence in popularity of hemp-derived products, from textiles to tinctures, gummies, skin creams, infused beverages, and much more. The hemp 'industry' is comprised of increasingly diverse and rapidly growing sectors of manufacturing and commerce, yet remains marred by questionable legality in many parts of the globe. The high demand for and popularity of hemp-derived CBD for infused products in the US continues despite the Federal Drug Administration (FDA) position stating CBD remains illegal as an ingredient in food, dietary supplements, animal feed, or for interstate commerce. In the absence of FDA oversight, the National Industrial Hemp Council of America (NIHC) plans to introduce guidelines for hemp product quality testing to support truth-in-labeling and screen for contaminants such as pesticides and heavy metals. The establishment and standardization of consumer safety benchmarks for hemp-derived products will be discussed in this webinar, including an overview of current state-mandated testing for cannabis in the US and suitability of this framework for hemp quality control testing.

In this 4-minute video, let Wayne highlight the most important features in a system for parallel evaporation if you are interested in reliable and reproducible results. Learn more about how:
-	A heated base and heated vacuum cover encourage vapor flow towards condenser
-	Rigids prevent backflow of sample and prevent sample contamination

❗ Analyst configuration for environmental and food quality control applications:
-	Cool appendix can help concentrate samples to defined residual volumes
-	Flushback module accessory improves analyte recovery by refluxing condensed solvent on glassware walls

❗ Polyvap configuration for simultaneous evaporation of up to 96 samples:
-	Intuitive vacuum control enables you to concentrate analytes
-	Racks for 4 to 96 samples enable unique versatility for high-throughput labs
-	With interface: fully automated solution for high analytical precision, reproducibility, safety
-	Vacuum vortex rotation that enables fast and gentle evaporation for volatile and heat-sensitive analytes
-	Sophisticated condenser that addresses safety and environmental concerns
-	Secondary condenser that can recover more than 95% of solvent

The Most Important Features of a Parallel Evaporator

Teach Me in 10

Have you ever wondered where a food’s flavor comes from? Most of us think it’s in food, but in reality, much of flavor has to do with our own personal perception of the food and how our brain interprets these signals when we’re eating. Yes, a significant part of flavor does include how certain molecules in a food either trigger our taste buds or receptors in our nasal cavity, but other aspects of flavor have much more to do with our own personal perception of the food such as our previous experiences with the food, memories, and emotions. So, what we know as “flavor” is actually a complex response to the physical and chemical “inputs” we experience when eating a food. This includes but is not limited to taste, aroma, color, texture, irritants, memories, emotions, and our personal experiences with the food. This week's Teach Me in 10 features Dr. Abbey Thiel, or "Abbey the Food Scientist", a postdoctoral researcher at Wageningen University with a focus in dairy foods and processing technologies. Dr. Thiel obtained her PhD in Food Science from the University of Wisconsin-Madison where she studied the microstructure of ice cream and whipped toppings. In her free time, Dr. Thiel runs a YouTube channel named [url][link]https://www.youtube.com/watch?v=y1kL90xqBuc&t=4s&ab_channel=AbbeytheFoodScientist[/link][name]“Abbey the Food Scientist”[/name][/url] where she breaks down everything related to Food Science.
