Gas chromatography-mass spectrometry (GC-MS) is the fastest-growing GC method. Mass detection, which can take a variety of forms based on the MS component, provides a dimension that conventional thermal conductivity or flame ionization detectors cannot.

Quality control is a key factor in making sure green tea dietary supplement products pack the same antioxidant punch as green tea leaves used for brewing beverages.

Routine monitoring of soil and groundwater are used to detect contamination from toxic chemicals. This contamination may be due to industrial runoff or wastewater effluent. Monitoring provides protection of local tributaries and surrounding property.

Gas chromatography-mass spectrometry (GC-MS) is the fastest-growing GC method.

Among the hyphenated mass spectrometry (MS) techniques, gas chromatography-MS (GC-MS) and high-performance liquid chromatography- MS (LC-MS) are the most notable. These methods combine the resolving power of high-resolution chromatography with the specificity and sensitivity of MS.
