App Note 10/2008 When analytes from a sample injection into an LC system are not completely flushed from the sample introduction hardware, valve and connections following the injection, a carryover […]
LEARN MOREApp Note 2/2008 Direct thermal extraction is a sensitive technique for the analysis of residual compounds in solid matrices such as polymers, films, powders, and fibers. This approach can be […]
LEARN MOREApp Note 5/2008 A robotic X-Y-Z coordinate autosampler commonly used for sample introduction in GC or HPLC can be used to perform a wide variety of sample preparation techniques using […]
LEARN MOREApp Note 8/2008 A novel purge tool for the GERSTEL MultiPurpose autosampler (MPS) under MAESTRO software control allows the headspace of a sample vial to be purged with inert gas […]
LEARN MOREApp Note 12/2008 A novel stir bar sorptive extraction (SBSE) procedure – “Sequential SBSE” was developed. Compared to conventional SBSE, sequential SBSE provides more uniform enrichment over the entire polarity/volatility […]
LEARN MOREApp Note 7/2008 In this study we describe the use of an automated dynamic headspace sampler for determination of volatiles in aqueous samples. This sampler uses a two-needle design to […]
LEARN MOREApp Note 6/2008 A fast SPE-GC-ECD method for the analysis of PCBs in waste oil was developed. A complete profile was obtained following SPE with a 12 minute GC run-time […]
LEARN MOREApp Note 4/2008 Static (equilibrium) headspace sampling is commonly used for GC determination of volatiles in solid and liquid samples. Since this technique relies on the analyte partitioning between the […]
LEARN MOREApp Note 3/2008 In this paper we report on the use of a novel dynamic headspace system (DHS) to determine several aldehydes, ketones and other fatty acid degradation markers in […]
