7.3 4100D analyser performance
Sample requirements
For best performance the flow, or pressure, supplied to the analyser should be kept at a
constant value for both normal sampling and for calibration gas input.
Temperature: 5 to 40
°C / 41 to 104°F
Dew point 5
°C / 9°F below minimum ambient
Condition: Oil free, non - condensing, filtered to 2
m
Vent: Each sensor outlet should be connected to a separate
atmospheric vent, free from any back-pressure.
(Consideration should be given to the toxicity and
asphyxiant nature of the sample gas when selecting a
vent location).
a) Flow driven options:
IR : 100 (min) - 250 (max) ml/min
Pm Purity: 100 (min) - 250 (max) ml/min
Pm Control: 100 (min) - 250 (max) ml/min
Pm Basic: 10 (min) - 100 (max) ml/min
Zr: 200 (min) - 400 (max) ml/min
Gfx: 500 (min) - 2500 (max) ml/min
b) Pressure driven options:
nominal 5psig / 35kPa
min. 2psig /14kPa, max. 8psig /56kPa
WARNING
This analyser (4102D and 4104D) is not suitable for use with flammable or corrosive
samples.
Internal autocal is unsuitable for use with toxic samples.
If toxic samples are present, the maximum pressure to the analyser must be limited
to 8psig by means of a suitable pressure release system.
CAUTION
Do not exceed the rated flow or pressure as sensor damage may result.
