f.Corrosive Gases
In applications where the sample stream contains corrosive gases, a complete drying of the sample is desirable, as most of these gases are practically inert when totally dry.
For corrosive applications, consult the factory.
WARNING
RADIOACTIVE SAMPLE GASES
Radioactive sample gases require the stainless steel tubing option.
Leaks must be corrected before introduction of flammable sample and/or application of electrical power. Liberally cover all fittings, seals, and other possible sources of leakage with a suitable leak test liquid such as SNOOP (PN 837801). Bubbling or foaming indicates leakage. Checking for bubbles will locate most leaks but could miss some because some are inaccessible to application of SNOOP. For positive assurance that system is
WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is of the type capable of analysis of sample gases which may be flammable. If used for analysis of such gases, the instrument must be either in an
If explosive gases are introduced into this analyzer, the sample containment system must be carefully
Internal leaks resulting from failure to observe these precautions could result in an explosion causing death, personal injury and/or property damage.
Supply air or inert gas, such as nitrogen, at 10 psig (69 kPa) to analyzer via a flow indicator with range of 0 to 250 cc/min. Set flow at 125 cc/min. Plug sample outlet. Flow reading should drop to zero. If not, system is leaking.
