App Note 4/2001 The elucidation of the “hoppy aroma note” in beer has always been a challenging task. The main reason without any doubt is the lack of sensitive and […]
LEARN MOREApp Note 9/2001 The analysis of contaminated soil and sludge samples for semi-volatile organic compounds (SVOC) has traditionally been performed using gas chromatography/mass spectrometry (GC/MS) (EPA SW-846, Method 8270). This […]
LEARN MOREApp Note 8/2001 Two extraction techniques that avoid solvent consumption and cut down the sample preparation to a minimum – Solid Phase MicroExtraction (SPME) and Stir Bar Sorptive Extraction (SBSE) […]
LEARN MOREApp Note 1/2001 Examples of optimized conditions for quantitation of residual hydrocarbons in polymeric packaging film and residual flavor components in recycled PET are shown. Techniques and equipment necessary for […]
LEARN MOREApp Note 3/2001 Analysis of samples containing polar matrix components such as water, glycols, sugars or surfactants by gas chromatography has usually required extensive cleanup such as liquid/liquid extraction, solid […]
LEARN MOREApp Note 7/2001 The benefits of using a Programmed Temperature Vaporizer (PTV) type inlets instead of hot split/splitless (S/SL) inlets for the liquid and headspace (HS) measurements of volatile compounds […]
LEARN MOREApp Note 2/2001 Strategies are shown that provide additional control of the partitioning of analytes into the PDMS phase during SBSE. Parameters such as sample pH, salt content and the […]
LEARN MOREApp Note 5/2001 A new sample preparation technique – Stir Bar Sorptive Extraction (SBSE) was evaluated for the enrichment of hop-derived solutes in wort and beer. SBSE offers an effective, […]
