WebIn the FT spectrometer, an interferometer is used instead of a diffraction grating. All frequencies (or wavelengths, ν ~ 1/λ) reach the detector at the same time. The spectrum is obtained by a mathematical calculation (a Fourier Transform). The FT spectrometer is more responsive, accurate and precise than a dispersive spectrometer. WebSingle quadrupole GC-MS. When gas chromatography is combined with a mass spectrometer that includes just one quadrupole, it is often referred to simply as GC-MS. GC-MS is well suited to the everyday analysis of samples where either targeted or untargeted analysis is required as these systems can be operated using either targeted selected ion …
