Abstract

We report on a novel gas spectrometry technique using pyroelectric thin-him arrays. The 1 x 50 element arrays of PZT are integrated onto silicon using a membrane structure. The experimental characterization of the pyroelectric elements shows both high voltage and current responses in defined frequency ranges. Mounting the array as a detector in a commercial spectrometer, we demonstrate its capability of detecting the infrared absorption curves of gases by the example of CO2. (C) 1998 Elsevier Science S.A.

Mass spectrometry

Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio.

Gas chromatography–mass spectrometry

Gas chromatography–mass spectrometry (GC–MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC–MS include drug detection, fire investigation, environmental analysis, explosives investigation, food and flavor analysis, and identification of unknown samples, including that of material samples obtained from planet Mars during probe missions as early as the 1970s.

Ion-mobility spectrometry–mass spectrometry

Ion mobility spectrometry–mass spectrometry (IMS-MS) is an analytical chemistry method that separates gas phase ions based on their interaction with a collision gas and their masses. In the first step, the ions are separated according to their mobility through a buffer gas on a millisecond timescale using an ion mobility spectrometer. The separated ions are then introduced into a mass analyzer in a second step where their mass-to-charge ratios can be determined on a microsecond timescale.
