Novel sample introduction units
MSA has designed and built a range of filter desorber units for the collection, trapping, and rapid desorption of vapour samples. Filters of various diameters and thicknesses are available for a range of vapour (and airborne particulate) detection applications.
Filters are available in a range of support media (paper, fabric, metal, glass, etc.) and can be coated to enhance trapping efficiency. Filter pellets are available containing a variety of sorbent types (tenax, carbotrap, molecular sieves, etc.). Maximum signal to noise is achieved by delivering the trapped analytes into the analytical device (mass spectrometer) as rapidly as possible. In MSA’s patented filter desorber, air or nitrogen is pre-heated and passed rapidly through the filter or pellet to effect efficient desorption.
Contact MSA to discuss the filters and desorber unit to suit your application. Desorber units can be fabricated to interface with a range of mass spectrometers.
