Un sistema specialistico di analisi dei gas per lo studio degli eventi transienti veloci
Misura la concentrazione di gas e vapori da pochi PPM fino ad alti livelli percentuali in meno di 0,2 secondi.
Lo spettrometro di massa HPR-20 QIC TMS è configurato per l'analisi di gas e vapori a pressione quasi atmosferica. È ideale per esperimenti in cui cambia rapidamente il gas e ha l'interfaccia di campionamento ricoperta di quarzo QIC da 0,9m.
Overview
The inlet, operating at 200 °C, provides response times of less than 150 ms to changes in gas composition with a 5 decade response time in < 200 ms.
The QIC inlet is coupled directly to Hiden’s Pulse Ion Counting (PIC) digital MS which is capable of measurement speeds of up to 500 data points/s over the entire 7 decade dynamic range.
Features
- 0.9 m fast response QIC capillary - 150 ms response time
- Open ion source and optimised pumping configuration for fast response
- Digital PIC detector - 7 decades continuous log scale
- Detection of low ppm to high % levels in < 200 ms
