IonSense DART mass spectrometers can now use nitrogen

IonSense has announced that its Direct Analysis in Real Time (DART) mass spectrometry systems can now utilise nitrogen gas and avoid the challenge of an unreliable helium supply. IonSense worked with Peak Scientific to validate Peak’s NG-3000A nitrogen generator for use throughout the IonSense product line. The NG-3000A system can deliver a supply of ultra-high purity nitrogen from ambient air for DART operation in both laboratory and mobile lab facilities.

The ionisation efficiency of excited nitrogen is high enough that almost all but the very smallest organic compounds can be easily ionised. Further, fragmentation is often reduced due to the lower energy of nitrogen metastables.
