App Note 1/1994 Thermal desorption is a well known technique for the analysis of volatile organic contaminants in air normally adsorbed on porous polymers and has been previously discussed [1]. […]
LEARN MOREApp Note 2/1994 Off-flavors in solid samples often cause analytical problems due to the necessity of sample pretreatment steps such as time consuming extractions followed by re-concentration of the resulting […]
LEARN MOREApp Note 5/2002 The use of stir bar sorptive extraction (SBSE) as a technique to extract volatiles and semi-volatiles from polar, especially aqueous matrices, has gained more and more acceptance […]
LEARN MOREApp Note 4/1996 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 3/2002 PTV inlets are often used for cryo-focussing and trapping of analytes for large volume, headspace, and thermal desorption applications. Selecting and optimizing trapping conditions for thermal desorption […]
LEARN MORETech Note 1/2000 System performance of the GERSTEL TDS in conjunction with an Agilent GC/MSD system was tested using a 43 component gas calibration mixture which was developed for the […]
LEARN MOREApp Note 7/2007 A method for characterization of airborne particles including the nanoparticles fraction with a diameter of 29-58 nm in roadside atmosphere is described. The method consists of thermal […]
LEARN MOREApp Note 4/2006 In this study we describe direct liquid injection techniques compatible with “dirty” samples containing non-volatile components. Using a glass liner that can be removed and replaced after […]
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 […]
