Entech's recently introduced technology, VASE (Vacuum Assisted Sorbent Extraction), aims to revolutionize the GC-MS research and testing industry by enabling solvent-free exhaustive extractions of volatile and semi-volatile compounds in a rapidly growing number of sample types and matrices while improving sensitivity and reproducibility. Entech Instruments Inc., a California-based analytical instrumentation company, is seeking an individual experienced with developing GC-MS applications with a particular history of using sample preparation and introduction techniques such as SPME, SBSE, SPE, or dynamic headspace for a variety of matrices, including water, soil, pharmaceuticals, packaging, and food & beverage.
