Airborne Measurements
Multiple Enclosure Device for Unfractionated Sampling of Air - automated sampler collects cryogenically dried air into 16 1.5 L glass flasks under actively controlled flow and pressure conditions. Designed for sampling for laboratory measurements of O2/N2, Ar/N2, 13CO2, and C18OO2, but suitable for other species.
