By concentrating a 2-liter air sample onto the absorbent-filled microtrap, detection limits of < 0.2 ppt have been achieved with the ADS GC-MS. The calibration and air analysis are alternated every two hours to provide six calibrated measurements per day. In 1997, two new identical ADS GC_MS instruments incorporating Hewlett Packard 5973.

Mass Spectrometry Data Center. The NIST Mass Spectrometry Data Center, a Group in the Biomolecular Measurement Division (BMD), develops evaluated mass spectral libraries and provides related software tools.These products are intended to assist compound identification by providing reference mass spectra for GC/MS (by electron ionization) and LC-MS/MS (by tandem mass spectrometry) as well as gas. Gas chromatography-mass spectrometry (GC-MS) is a nonoptical-based indirect method, in which the separation of the compounds is based on the flow of inert helium or nitrogen gas. It involves the profiling and signature of released specific volatile organic compounds (VOCs) in the stressed plant indicative during the infection 
Relatively cheap and reliable GC-MS systems are now a feature of many clinical biochemistry laboratories and are indispensable in several areas where the analysis of complex mixtures and unambiguous identification is required e.g. screening urine samples for inborn errors of metabolism or drugs.

With limits of detection (LODs) in the low-ppt range, these methods are sufficiently sensitive to measure background levels of chloroform in the general population as well as chloroform levels at which health effects might occur after short-term or long-term exposure. However, many studies do not report the method detection limit and/or th LC-MS-MS used Cliquid®2.0 software for data processing and acquisition in MRM mode.
