The GERSTEL Spring Open featured strategies on how to improve your LC or GC analyses efficiency. It also provided a great opportunity to explore cost saving functionality, view live product demonstrations and meet industry experts.
GERSTEL, Inc. and Tufts University Sensory and Science Center (TUSSC) announce an upcoming Sensory-directed Chemical Analysis workshop tentatively scheduled for May 30th – 31st, 2018, at the Tufts University Sensory and Science Center in Medford Massachusetts.
This year at Pittcon 2018 GERSTEL will unveil a series of new products and initiatives to help you succeed, including: • The latest sample introduction and sample preparation technology using the MPS Robotic platform. • Advancements in analytical thermal desorption sampling and analysis. • An exciting new extraction device from the inventor of SPME. • Live demonstration of the SIFT-MS technique. We will also be presenting posters on a wide variety of topics. Visit us at Booth 3001 to learn more.
In 2017 alone there have been 12 separate news reports of Americans in cities around the United States complaining about the smell and taste of their drinking water due to the compounds MIB and Geosmin.
Automated SIFT-MS is the result of the recent collaboration between GERSTEL and Syft Technologies to provide turnkey automated platforms for SIFT-MS solutions in routine and R&D laboratories.
The flavor of a food or beverage engages far more sensory input than taste alone. From a biological perspective, flavor may be defined as the sum of taste, aroma (smell sensation), texture (touch sensation), and other physical features (e.g., temperature) that create mouth feel. The contributions of taste and aroma to flavor are made through chemoreception: the physiological response of sensory nerves to the volatile organic chemicals (VOC) released by foods and beverages. Although these VOCs are present at very low concentrations, they activate a highly specialized set of sensory connections in the brain, activating psychological responses that range from instinctual perception of food safety, to recognition of a previously eaten food, to even higher-order associations of a food with a memory or emotion.
The coveted “new car smell” is now known to result from chemicals emitted from plastic and leather parts that make up the interior of automobiles. These parts emit volatile organic compounds (VOCs; e.g., benzene, formaldehyde), semi-volatile organic compounds (SVOCs; e.g., phthalates, trichlorophenyl phosphate [TCPP]), and other chemicals. For example, TCPP is a flame retardant often found in polyurethane foams. Although TCPP provides safety by reducing the risk of these foams igniting in a fire or accident, its semi-volatile nature causes it to release into the car’s interior, where passengers can be exposed to its vapor.
As of February 2017, 29 states in the US (plus the District of Columbia; DC) have legislation, either in place or in progress, permitting the use of medical marijuana. Another 16 states have decriminalized possession, and 8 states (plus DC) have legalized marijuana for recreational use. With such changes in legislation, it is no surprise that North America’s cannabis sales increased by 30% between 2015 and 2016. Furthermore, they are projected to post an impressive 25% compound annual growth over the next 5 years, or by 2021. Tom Adams, editor-in-chief for ArcView Market Research said, “The only consumer industry categories I’ve seen reach $5 billion in annual spending and then post anything like 25% compound annual growth in the next five years are cable television (19%) in the 1990s and the broadband internet (29%) in the 2000s.”1
Strong interest at the state level for legalization of both medical and recreational marijuana use has created a marijuana production industry in the US that is growing rapidly. In fact, half of the states have already legalized marijuana for one or both of these uses. The number of states allowing use of marijuana could also continue to grow after the fall election cycle, adding more impetus to the growth of the marijuana industry.
Currently, 26 US states have approved medical marijuana in their legislature, while another 16 have decriminalized possession and 4 states (plus DC) have legalized marijuana use. Marijuana per se driving laws for driving under the influence of drugs (DUID) were enacted in 17 states, making it illegal for someone to operate a vehicle with detectable THC (Δ9-tetrahydrocannabinol) or its major metabolite, THCOOH (11-nor-9-carboxy-THC), in blood and/or urine. A majority of those states have zero tolerance laws while some of them enforce specific THC driving cutoffs (1-5 ng/mL THC). However, low THC levels can be detected in frequent cannabis smokers’ blood up to 30 days after last use during sustained abstinence, making cannabinoid data interpretation difficult.
