How does a Hapsite work?
To accomplish this, HAPSITE ER employs a probe distance indicator that delivers visual feedback for the probe’s optimal placement relative to the spill, drum, or other point source. It’s simple. When using Survey mode (MS only), the bar turns green when the user is drawing sample at the proper distance.
What is Hapsite?
HAPSITE ER is the only person-portable Gas Chromatograph/Mass Spectrometer (GC/MS) that requires minimal training to deliver qualitative and quantitative lab-quality results-in the field, in less than 10 minutes.

Which detector is used in GCMS?
General-Purpose Detectors. The FID is the most common detector used in gas chromatography. The FID is sensitive to, and capable of detecting, compounds that contain carbon atoms (C), which accounts for almost all organic compounds.
Why is methanol used in GCMS?
Generally low boiling solvents, such as hexane or methanol, are used as they move rapidly through the column. In many analyses, the MS detector is turned off for some time after the injection to allow the solvent to move through the column.
Can DCM be used in GCMS?
Abstract. The injection of analytes into a gas chromatography-mass spectrometry (GC-MS) system using dichloromethane (DCM) as solvent led to gradual deterioration of chromatographic signals, with significant tailing and loss of sensitivity for C17+ hydrocarbons.
What is the GC detecting?
GC is routinely used in air monitoring to detect volatile organic compounds, or VOCs, which may arise from environmental pollution, pesticides and explosives. GC can be used to track and identify VOCs both indoors for headspace analysis and outdoors, for health, safety, and security.
Which is mobile phase is used in GC?
The mobile phase used in GC is an inert gas, such as nitrogen, helium, or hydrogen. The mobile phase is usually referred to as a carrier gas; when a mixture of substances is injected at the column inlet, each component is carried toward the detector by the mobile carrier gas.
What solvent is used in GCMS?
Various solvents including ethyl acetate, hexane, methanol, dichloromethane and acetone have been used for the extraction of 1,4-dioxane, among them the ethyl acetate was found to be the most efficient extracting solvent.
How do you choose a solvent for GCMS?
The solvent used in GCMS are mostly a-polar solvents since polar solvents can cause disturb the chromatography, like fronting, tailing and peak splitting. Generally, a solvent is chosen with a much lower boiling than the compounds. If the boiling points are to close distortion of the chromatography will happen.
