Instrument: Real-Time/on-board gaschromatography

Name Real-Time/on-board gaschromatography
Acronym Airmotec-VOC-GC
Manufacturer Airmotec
Operated by METAIR
Operated onboard

Instrument type

Name Gas Chromatograph (GC)
Acronym Gas Chromatograph

Principle of operation

Measured parameter Trace gas concentrations especially VOC
Operating principle

Onboard gas chromatography with quasi-continuous sampling in 10-minute intervals (rotating sampling tubes and cryo-trap)

Measurement(s) Gas Phase

Dimension and weight

External dimension 19"/4HU, about 55 cm deep, plus externals
Weight 22.0

Performance

Operating mode In situ
Range

Resolution

Sensitivity

Accuracy

Bandwidth

Modifications

diverse, especially operational considerations

Operational restriction

several, both in terms of accuracy (e.g. the necessity to avoid diffusion of high ambient VOC concentrations), and in terms of safety (FID with H2). The use in the ventilated underwing pods of MetAir's DIMO is well tested since 1994, but, a use in a cabin might need a box with protective gas, and might be a challenge for certification

Operational requirements

240 VAC, 70 Watts, RS-232 with different non-standard handshake (best with original DOS-based program)

Certification approvals

only for the well-ventilated underwing-pods of the DIMO, permanently watched by the operator (real-time display in the cockpit).

Additional information

Needs a preparation phase of at least 2 weeks before any campaign.

Access, host and processing

Access

on request to info@metair.ch

Could also fit on any aircraft having the following characteristics
