Effective sampling fl ow rate
0.5 mL ± 0.15 mL/min
Sample inlet (INLET) / sample outlet (OUTLET)
2 mm × 4 mm dia. fl ared tube joint
PURGE Purge air port, one-touch type joint for dia. 6 mm tube
In the cases listed below, the interior of the unit should be cleaned with purge
gas to prevent adverse effects on the optical system and electrical circuitry.
- If the cleanliness of usage environment is lower than
classifi cation of air cleanliness class 6 defi ned by
ISO 14644-1
- If the temperature of the sample fl uid is lower than
the environmental temperature, so that moisture
condensation may occur on the fl ow cell
- If there is the possibility that corrosive gases in the
vicinity may intrude into the unit
- If there is the possibility that corrosive gases in the
sample fl uid may permeate through the internal tube
Purge gas requirements
Clean dry air: CDA
- Tempe15°C to +35°C
- Relative humidity not causing condensation
- Flow rate 3 L/min to 10 L/min
- Other: Under special conditions, nitrogen gas or other
gases may also be used
