E.3.2. Gas Analyzer
Sensor head
2 to 9 channel NDIR type gas analyzer measuring at 4 to 10 µm. Data
acquisition rate 10 kHz(sample rate 20 Hz/channel)
Compensations
ISA OR+:
Automatic compensation for pressure and temperature.
Manual compensation for broadening effects on CO

Calibration
No span calibration is required for the IR bench. An automatic Zeroing is
performed typically 1 to 3 times per day.
Warm-up time
ISA OR+:
<20 seconds (Concentrations reported, automatic agent
identification enabled and full accuracy)

Primary agent threshold
(ISA OR+)
0.15 vol% When an agent is identified, concentrations will be reported even
below 0.15 vol% as long as apnea is not detected
Secondary agent threshold
(ISA OR+)
0.2 vol% + 10% of total agent concentration
Agent identification time
(ISA OR+)
< 20 seconds (typically < 10 seconds)
Total system response time
ISA OR+ < 4 seconds
