WARNING:
i) Quartz reaction tube located in total sulfur furnace
ii) Dual Seal maximum working pressure is 2 PSI
iii) Leaks are indicated by monitoring the ball in the H2/Sample Flow meter during a pressure
test.
(a) Lack of flow can indicate the possibility that a failed primary seal condition could
exist in the Quartz Tube/heater assembly.
2.3 Hydrogen
CAUTION: Hydrogen is extremely flammable. Use Caution when handling.
The total sulfur analyzer requires ultra-high purity (UHP) hydrogen at a flow of 200-300 cm³/min.
UHP Hydrogen has a minimum specified purity of 99.9999%. Lower grades of hydrogen may
contain sulfur compounds or other impurities which will cause inaccurate results. Consult the
factory calibration sheet for the flow rates for your application.
