The document introduces the UNITY™-Air Server of Airtech, which is a new technology for online monitoring of volatile organic compounds (VOCs) in air. This technology can be coupled with a gas chromatograph (GC) or a gas chromatograph/mass spectrometer (GC/MS) and is suitable for unattended operation in remote field.
This document provides a technical overview of the UNITY-Air Server, a thermal desorber system designed for the round-the-clock, unattended monitoring of volatile organic compounds (VOCs) in ambient air. The system utilizes cryogen-free concentration technology, combining automated controlled-flow sampling with an electrically-cooled sorbent-packed focusing trap to eliminate the need for liquid cryogens.
| Sampling rate | 10 mL/min |
|---|---|
| Sampling time | Various |
| Cold trap low temperature | -15°C |
| Cold trap high temperature | 300 °C |
| Cold trap hold time | 5 min |
| Transfer line temperature | 100 °C |
No, the system combines automated, controlled-flow sampling with cryogen-free concentration technology and does not require liquid cryogen.
The sampling rate used for determining breakthrough volumes is 10 mL/min.
Yes, the system is designed for unattended operation in remote field locations and requires no user intervention during trials.
