A gas chromatograph mass spectrometer combines gas chromatography and mass spectrometry to identify and quantify substances. The device separates the substance into components which are detected ...

The Gas Chromatograph Mass Spectrometer (GCMS) experiment was carried aboard each of the Viking spacecraft landers that reached the red planet in 1976. It was intended to detect evidence of bological ...

In gas chromatography (GC ... It is here the sample is broken into its component chemicals. A mass spectrometer (MS) is then analyses these chemical components. The individual molecules are ...

The gas chromatography system heats and volatilizes liquid ... After exiting the stationary phase column the sample enters the mass spectrometer. The mass spectrometer detector identifies analytes ...

The Shimadzu single quadrupole GCMS-QP2020 NX gas chromatograph-mass spectrometer (GC-MS) not only boasts the best performance in its class, but also the highest efficiency. This high-end single-quad ...

Coupled to the mass spectrometer, a 1200 series rapid resolution LC system offers a unique combination of flexibility, resolution and speed. Benefits include the ability to run both rapid resolution ...

Scientists from the China University of Sciences combined magnetic solid-phase extraction (MSPE) with gas chromatography–mass ...

One of the experiments used a gas chromatograph-mass spectrometer (GCMS), which detected chlorinated organic compounds. Initially, these were considered contaminants, but it is now understood that ...
