The Unity 2 Air Server Series 2 Operators Manual introduces the Air Server accessory for Unity 2. The manual provides steps on how to set up the Air Server, create methods, run analyses, and stop sequences.
The Air Server Series 2 is an accessory for the UNITY 2 Thermal Desorber that extends the compatible sample range to include whole air and gas samples, such as those from canisters or Tedlar bags. It connects to the UNITY 2 via inert switching valves and link tubing, allowing for the quantitative sampling and retention of volatiles ranging from acetylene to n-C4.
| Compatible Volatiles | acetylene to n-C4 |
|---|---|
| Pressure Range | sub-atmospheric to 50 psig |
| Inlet Ports | three (or eight) |
| Split Flow Range | 5-100 ml/min |
The system supports Helium (He), Hydrogen (H2), and Nitrogen (N2) as carrier gases.
Yes, if the sample pressure is low (below 10 psi), atmospheric, or just below atmospheric, a pump is required to pull the gas-phase sample through the system.
Yes, the leak test is optional in on-line mode, but it is recommended to run an initial leak test to check system integrity before initiating a series of runs if the test is deselected.
