FlowMate Adaptors
FlowMate adapters for tool-free connections to threaded fittings. Tool tightened connections can be frustrating, time consuming, and they can increase the likelihood of damaging threads and rendering valuable hardware unusable. Entech is introducing two new adapters based on ultra-reliable face sealing technology. Watch the video or scroll down to learn more. For a limited time, […]
Applet: Beyond THC and CBD: Solvent Free Headspace Extraction and GC-MS Profiling of Terpenes and Cannabinoids in Cannabis Flower and Products
Authors: Sage J. B. Dunham, Victoria L. Noad, Bailey S. Arakelian & Daniel B. Cardin Introduction Compositional analysis of products, including any contaminants present, from raw materials to finished products is crucial to ensure quality and safety. Headspace Sorbent Pens (HSPs) are used with the technique, Vacuum Assisted Sorbent Extraction (VASE), to extract volatile organic […]

Vacuum-Assisted Sorbent Extraction: An Analytical Methodology for the Determination of Ultraviolet Filters in Environmental Samples
Authors: María J. Trujillo-Rodríguez, Jared L. Anderson, Sage J. B. Dunham, Victoria L. Noad & Daniel B. Cardin Abstract Vacuum-assisted sorbent extraction (VASE) has been applied in combination with gas chromatography-mass spectrometry for the determination of UV filters in water samples. VASE is a variant of headspace extractionwhich was developed in conjunction with the sorbent […]
POSTER: Chemical Profiling of Cannabis Infused Products using Solvent-Free Headspace Extraction and Thermal Desorption GC-MS
Authors: Sage J. B. Dunham, Victoria L. Noad, Bailey S. Arakelian & Daniel B. Cardin Overview A solvent free headspace extraction approach – vacuum assisted sorbent extraction (VASE) – is applied in combination with thermal desorption (TD)-gas chromatography-mass spectrometry (GC-MS) to examine the chemical composition of cannabis and cannabis infused consumer products. Application of VASE […]
POSTER: Cannabinoid & Terpene Profiling of Cannabis by Solvent-Free Headspace Extraction and Thermal Desorption-GC-MS
Authors: Sage J. B. Dunham, Victoria L. Noad, Bailey S. Arakelian & Daniel B. Cardin Overview The specific chemical composition of cannabis is responsible for the fragrance and flavor of the product, the experience of a recreational high, and the medicinal benefit. In a phenomenon known as the “entourage effect”, evidence further suggests that compounds […]
A New Cryogenless TO15 Canister Preconcentrator with Reduced System Carry-Over When Exposed to Higher Concentration Samples
OVERVIEW A new preconcentrator design is presented which eliminates the need for liquid nitrogen or complicated electronic cooling while performing US EPA Method TO15 analysis1. A new technology called Multi-Capillary Column Trapping System (patent pending), or MCCTS, is used to concentrate all TO15 compounds at 35°C, which is achieved simply by using cooling fans. Two […]
POSTER: Trace-Level Quantification of SVOCs in Water via Vacuum Assisted Sorbent Extraction (VASE) Thermal Desorption-GC-MS
Authors: Sage J. B. Dunham, Victoria L. Noad, Bailey S. Arakelian & Daniel B. Cardin Overview Current analytical methods for evaluating volatile and semi volatile organic compounds (VOCs & SVOCs) in water often require large sample volumes (1 L or more), are labor intensive, and rely upon liquid-liquid extraction into organic solvents. Here we present a sensitive, […]
POSTER: Vacuum Assisted Sorbent Extraction (VASE) Thermal Desorption-GC-MS: A Robust, Solvent-Free Technique for Chemical Residue Analysis
Authors: Sage J. B. Dunham, Victoria L. Noad, Bailey S. Arakelian & Daniel B. Cardin Overview In the 30 years since the invention of solid phase microextraction (Belardi & Pawliszyn, 1989), headspace (HS) extraction has developed into a powerful family of techniques for both targeted and untargeted chemical analysis of volatile and semi volatile compounds. We recently developed […]
