This document describes the performance of the Agilent Model 255 NCD for analyzing 2-pyrrolidone and 1-vinyl-2-pyrrolidinone, and shows that it can replace the nitrogen-phosphorus detector (NPD).
This document introduces the Agilent Model 255 Nitrogen Chemiluminescence Detector (NCD), highlighting its capability to replace Nitrogen-Phosphorus Detectors (NPD) for analyzing 2-pyrrolidone and 1-vinyl-2-pyrrolidinone in adhesive samples. The text demonstrates that the NCD offers superior selectivity, sensitivity, and ease of use compared to NPDs.
| Selectivity | > 10^7 gN/gC |
|---|---|
| Sensitivity | <5 pg/sec |
| Burner Temperature | 800°C |
| Hydrogen Flow Rate | 25 mL/min |
| Oxygen Flow Rate | 10 mL/min |
Yes, the evaluation demonstrated the Model 255 NCD could easily replace a NPD to monitor 2-pyrrolidone and 1-vinyl-2-pyrrolidinone.
No, the NCD is straightforward to use and requires less day-to-day maintenance than an NPD.
