Automatic GC-FID solution for monitoring SVOCs, VOCs and PAHs in ambient air

Feb 23 2021 Read 241 Times

The fully automatic airmoVOC C6-C20+ auto-GC-FID analyser is specifically designed to carry out the measurement of hydrocarbons from C6 to higher than C25 (linear alcanes) with a sensitivity in the range of low ppt (ng/m3).

This highly regarded instrument from Chromatotec measures naphthalene, 2-methyl-naphtalene, 1-methyl-naphtalene, acenaphthene, acenaphthylene, fluorene, phenanthrene and anthracene as standard.  The aimoVOC C6-C20+ was also recently used for benzo(a)pyrene analysis. It has already been deployed in various French reference institutes and universities to monitor PAHs at industrial sites, tropical forests and sites under decontamination.

When coupled with Quadrupole MS, any unexpected or unknown compounds are automatically identified thanks to the internal NIST library embedded in the system’s internal computer. With detection limit as low as 1 ppt for benzene or naphthalene the system can measure gaseous PAHs in ambient air in continue up to fluorene and linear alcanes up to N-Hexadecane. The instrument is designed to avoid the risk of contamination caused by other molecules that may be present in the sample. An integrated, internal calibration system is used to validate the data and to ensure analytical system is operating with stability. This cylinder free solution includes embedded gas generators and calibration controlled by GC in rack or wall mounted box.

Chromatotec’s  Vistachrom Software is used to pilot the instrument as well as the peripherals (e.g. gas generators) which can be provided with the instrument system.
