In cases where very low limits of detection are needed, halogenated species are frequently analyzed using an electron capture detector coupled to a gas chromatograph.

For the space version, Ferrando uses special forms of two amino acids that he can detect on an instrument known as a gas chromatograph mass spectrometer.
25.
These compounds, which have gothic names like cadaverine and putrescine, are collected in a vial and from there fed into a gas chromatograph that identifies them.

Investigators in Calverton are using tools such as a gas chromatograph, which separates organic components, and a mass spectrometer, which identifies each component by its molecular weight.
28.
Samples that come up positive are double checked by a gas chromatograph mass spectrometer, the " gold standard " test that identifies a substance's exact molecular structure.
