Airborne Chromatograph for Hydrocarbons

TACOH

Principle of the Measurement:
1. Sampling of VOCs in a cryostat
2. Injection onto a chromatographic column
3. Detection with either a flame-ionization detector (FID) or a mass spectrometer (MS)

Species Measured:
1. Alkanes
2. Alkenes
3. Alkynes
4. Aromatics
5. Biogenic VOCs (isoprene, monoterpenes)
6. Alcohols
7. Ketones
8. Aldehydes
9. Nitriles
10. Dimethyl sulfide
11. Halocarbons
12. Alkyl nitrates

Time response:
5 minute sample time
1 sample per 30 min

Detection limit:
0.1-10 pptv

Manufacturer:
Home-built
