| Name | Real-Time/on-board gaschromatography |
| Acronym | Airmotec-VOC-GC |
| Manufacturer | Airmotec |
| Operated by | METAIR |
| Operated onboard |
| Name | Gas Chromatograph (GC) |
| Acronym | Gas Chromatograph |
| 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 |
| External dimension | 19"/4HU, about 55 cm deep, plus externals |
| Weight | 22.0 |
| 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 | on request to info@metair.ch |
| Could also fit on any aircraft having the following characteristics | |
