Description The Servomex SERVOPRO HFID analyzer is an exceptionally accurate Flame Ionization Detection (FID) gas analyzer designed for measuring hydrocarbons concentrations in gaseous samples. The analyzer utilizes a highly sensitive flame ionization detector for measuring volatile hydrocarbon concentrations in industrial stationary source or mobile source (such as vehicle or engine certification) emission applications. The SERVOPRO HFID family of heated analyzers includes the standard unit reporting only total hydrocarbon (THC) or it can be equipped with a non-methane hydrocarbon “cutter”...

ensure that the moisture content does not fluctuate more than a few % and that the O 2 levels in the sample are always maintained at 10% or above in order for the FID to remain lit. If these conditions are not met then the analyzer performance will be adversely affected and/or it may damage the cutter material. If using 100% H2 fuel and running the CH4 mode in the NMHC version, make sure the moisture content does not fluctuate more than a few % or lower and that the O2 levels are always maintained at 10% or CAUTION above, if not then the analyzer performance will be adversely affected...

processing the data according to the requirements as prescribed by the regulatory body. In many cases this is not a simple subtraction process, so please consult your regulatory agency to determine how you are required to obtain the final NMHC value. A heated oven (191°C) contains a burner and an optional heated pump. The small flame of the burner is elevated and sustained by the regulated flows of air and either pure hydrogen or a 40/60 mixture of hydrogen and helium (a hydrogen / nitrogen option is available but is not offered as a standard product – consult Servomex if this option is...

Heated Oven The heated sample gas is maintained above its dew point by a self-contained internal oven. The oven temperature is adjusted at the factory to be controlled at 191°C. The sample gas is maintained at this elevated temperature until it exits the analyzer’s bypass outlet, preventing any loss of hydrocarbon concentration in the sample due to condensation. Because the sample gas is analyzed HOT/WET you must make sure to keep the vent tubing on the bypass outlet short and pointed downwards to avoid plugging the vent line with condensed moisture. Flow System Combustion air and fuel used...

Fuel Requirements The SERVOMEX factory configures the SERVOPRO HFID analyzer for either 100% Hydrogen or 40%/60% Hydrogen/Helium fuel. Please make sure to use the correct fuel as specified on the fuel label affixed to the back panel of the analyzer. WARNING: Use of incorrect fuel will damage the instrument and could cause an explosion. Before initial startup, carefully check the fuel supply system to the analyzer for leaks. The operating technician should be properly trained for working with hazardous materials. Potential Sample Pump Damage The analyzer can be calibrated using the optional...

2. Always use a second wrench on the body of the filter housing when attempting to inspect or replace the filter. 3. Always allow the filter housing to cool to room temperature before attempting any maintenance. WARNING: Never attempt to disassemble or reassemble the filter housing while it is hot. 4. The sealing of the filter housing is accomplished with the o-ring. Do not over tighten. Re-assembly of the filter housing should be sealed just past finger-tight and only when the filter housing is at room temperature.
