Characterization of gas desorption from solid samples with small size by TDS.

Performance evaluation of thermal desorption system (TDS) for detection of basic drugs in forensic samples by GC-MS.

Stir bar sorptive extraction is an innovative sample extraction technique that can be used to process blood, urine, and tissue samples for routine drug screening in the forensic toxicology laboratory. The Gerstel Twister desorption unit (TDU) system is a multifunctional desorption unit capable of determining the presence of analytes from liquid samples after extraction using the Twister stir ba...

Simultaneous Determination of Disinfection By-products in Water Samples from Advanced Membrane Treatments by Headspace Solid Phase Microextraction and Gas Chromatography-Mass Spectrometry

A headspace-solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) method has been developed for the simultaneously determination of 20 disinfection by-products (DBPs) in water samples from reverse osmosis (RO) membranes. Selected compounds belong to different families including: trihalomethanes (THMs), halogenated acetonitriles (HANs), halogenated nitromethanes ...

Thermal Desorption Mass Spectrometry (tds) Application on Mass Metrology

A new device has been developed for the study of physisorbed elements on polished and large surface used in mass metrology. This technique, based on the analysis by mass spectrometry of desorbed molecules caused by heating under vacuum from the analyzed surface, is presented. The first application of this device is the study of the current and future mass standards to understand the reactivity ...
