App Note 6/1996 The combination of a new thermal desorption module with a cooled injection system (TDS-2,CIS-3, GERSTEL) now provides a powerful thermal desorption system for direct analysis of volatile […]
LEARN MOREApp Note 2/1997 The novel GERSTEL Online TDS G was developed to allow fast, reliable and continuous analysis of airborne compounds. For the described application the total analysis time, including […]
LEARN MOREApp Note 2/2014 This note presents a fully automated analysis system for the determination of THC and its metabolites in blood serum. Automation is based on the GERSTEL MultiPurpose Sampler […]
LEARN MOREApp Note 7/2013 Analyzing blood serum for opioids, cocaine and metabolites is a routine task in forensic laboratories. The most commonly used methods involve several manual or partly-automated sample preparation […]
LEARN MOREApp Note 6/2005 This study demonstrates the feasibility of extracting THC from an aqueous matrix using Stir Bar Sorptive Extraction (SBSE) followed by thermal desorption into the injection port of […]
LEARN MOREApp Note 12/2012 16 phenolic compounds along with typical drinking water off-flavor compounds like geosmin, 2-methylisoborneol(MIB), and 2,4,6-trichloroanisole (TCA) were determined using two different approaches: 1) In-situ derivatization with acetic […]
LEARN MOREApp Note 5/2005 This paper applies SBSE coupled to thermal desorption (TD)-GC/MS to determine ultra-trace levels (sub-ng/L to ng/L) of compounds in aqueous samples.
LEARN MOREA MultiPurpose sampler (GERSTEL MPS), designed for liquid large volume, gaseous and headspace samples was tested for its suitability in the GC/MS analysis of organic volatiles in human urine. Headspace […]
LEARN MOREThis paper describes a novel ethylene glycol (EG) and silicone based combined sorbent phase developed for stir bar sorptive extraction (SBSE) using the GERSTEL Twister™. EG-Silicone, polyacrylate (PA), and polydimethylsiloxane […]
