Ambient RAC 5-Gas Sampler

The Distributor Ambient RAC 5-Gas Sampler tests for sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), ammonia (NH3), aliphatic aldehydes (R-CHO) and other pollutant for which there is a suitable chemical reagent (absorbing solution). This versatile instrument can be used to accurately sample a single gas or up to five different gases simultaneously. Simplified design, ease of assembly and modular components permit easy changes in sampling train configurations to meet variable sampling requirements.
The 5-Gas system can be used virtually anywhere that line power is available and is used for area surveillance, plant perimeter surveys and interior air quality monitoring or evaluation.
5-GAS SAMPLER COMPONENTS
The RAC 5-Gas Sampler is furnished complete in a portable all-weather shelter and is ready-to-operate (reagents not included). This self-contained design includes a heavy-gauge steel cabinet with a hinged lockable lid, two separate compartments and a weather-resistant baked enamel finish that is suitable for use under most climatic conditions. The preassembled complete sampling train and a thermostatically-controlled heater assembly are installed in an insulated compartment; the systems vacuum pump, vacuum gauge and electrical junction box are installed in the second compartment, which has louvers on three sides for heat dissipation. A 3-wire power cord is supplied as standard.


OPERATION
In operation, the vacuum pump draws ambient air in through the conical rain shield and inlet tube (the rain shield is inverted to prevent precipitation from entering the sampling device). Particulate matter entrained in the air sample is trapped in a membrane-type filter beofre air enters the inlet manifold. The inlet manifold then divides the air stream into five equal volumes that flow through Teflon tubing to the bubblers. Each bubbler has a 2-hole cap with a standard glass bubbler tube, either constricted or fritted, on the inlet port. The sample air passes through these tubes into 50ml of reagent (absorbing solution) contained in each bubbler.

Features:

Critical orifices provide 200 ml/min flow rate (nominal) through system
All orifices protected by in-line filters & moisture traps to prevent clogging & flow reduction
Sampling cabinet equipped with thermostatically-controlled heater to
prevent reagent freezing
All-weather shelter is lightweight, portable and easy-to-operate
Polypropylene bubblers with threaded interchangeable caps (2-hole cap for sampling & solid cap for transport)
Optional timing mechanisms available
