6. Is this a new requirement or a follow-on to an expiring award?

☒ New requirement ☐ Follow-on to an expiring award

7. Describe the requirement. Please note that the requirement is the minimum acceptable specification or capability, and is not necessarily the best in the industry. Please note whether any additional follow-on work is anticipated in response to the current proposed effort.

The system features the analysis of trace nitrogen in balance helium and oxygen via Pulsed Discharge Helium Ionization Detector (PDHID).

The system also features the analysis of trace nitrous oxide (N2O) in balance helium and oxygen via Electron Capture Detector (ECD).

The sample is delivered directly from the incubation vessel as shown in Figure 2 of K. Butterbach-Bahl, G. Willibald, and H. Papen, “Soil core method for direct simultaneous determination of N2 and N2O emissions from forest soils.”

The sample must be at positive pressure to deliver a valid sample to the GC.

Multiple incubation vessels can be automated via Valco stream selector valve.
