The only reference to provide both current and thorough coverage of this important analytical technique Static headspace-gas chromatography (HS-GC) is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the costly and time-consuming preparation involved with traditional GC.

Our gas chromatography (GC) solutions are designed to be customized so that they can fit any laboratory workflow. From Thermo Scientific Instant Connect injector and detector modules, to our performance-leading Thermo Scientific mass spectrometers, we offer the largest portfolio of GC solutions that enable you to innovate as well as customize your gas chromatography applications.

Chromatography dates to 1903 in the work of the Russian scientist, Mikhail Semenovich Tswett, who separated plant pigments via liquid column chromatography. German physical chemist Erika Cremer in 1947 together with Austrian graduate student Fritz Prior developed the theoretical foundations of GC and built the first liquid-gas chromatograph, but her work was deemed irrelevant and was ignored

in favor of the gas phase, such as the temperature of the vial and the matrix composition,1 allow for the maximization of the concentration of the target analytes in the headspace, increasing the efficiency of the extraction and the sensitivity of the method. Procedure A Plunger stoppers (2 stoppers/vial) were put into 20 mL HS vials.

The term chromatography describes a variety of techniques that are used to separate a substance or mixture into its components. Many products are used during different stages of chromatography workflows, including solvents, standards, columns, vials and closures, and chromatography paper.

Mar 07, 2020 · Sample/ standard preparation: N/A; Calibration procedure: Switch on the instrument as per the instrument SOP. The analyst shall open the carrier gas like Nitrogen or Helium from the cylinders or use a gas generator for respected carrier gas. Ensure that Hydrogen and zero air shall be off, whenever checking carrier gas flow.

The GC-MS is composed of two major building blocks: the gas chromatograph and the mass spectrometer.The gas chromatograph utilizes a capillary column whose properties regarding molecule separation depend on the column's dimensions (length, diameter, film thickness) as well as the phase properties (e.g. 5% phenyl polysiloxane).

When it comes to flexibility, ease of use and sensitivity, one family of gas chromatography (GC) systems stands apart: Clarus. Our family of GC instruments delivers the performance you need, day after day, and is compatible with virtually all sample introduction systems, including our world-class TurboMatrix, Headspace, and Thermal Desorption.

Apr 16, 2021 · Nitrosamine impurities in angiotensin II receptor antagonists (sartans) containing a tetrazole group represent an urgent concern for active pharmaceutical ingredient (API) manufacturers and global regulators. Regarding safety, API manufacturers must develop methods to monitor the levels of each nitrosamine impurity before individual batch release. In this study, we developed and validated a
