Typical applications for Ansel products include:
Air and dust sampling determines the level and types of viable fungal propagules within building trouble spots, and suggests the presence of significant indoor mold growth sites ("amplifiers").
This type of instrumentation is required to check hydrocarbons that are present in emissions that escape into the atmosphere through industrial smokestacks. The EPA regulates how much of certain chemicals, such as CO 2 , CO, SOx, NOx etc., can be present in the gases that are emitted to the atmosphere.
A portable flame ionisation detector is used to measure concentrations of hydrocarbons within a sampled gas. The presence of hydrocarbons is detectable by burning the sampled gas in an air-hydrogen flame. The presence of hydrocarbons in the sampled gas, when burnt with an air-hydrocarbon mix, causes high level of ionisation. The level of ionisation is proportional to the number of carbon atoms within the sample which is taken by the diaphragm pump.
In many countries, safety devices are required for the monitoring and protection of fuel oil in buried tanks. To prevent the leakage of fuel, double-walled tanks or plastic covers (for older, single-walled tanks) are used. In between the double-wall a vacuum is built up and monitored by a pressure detector. Pressure variations and very small leakage on tube fittings and threaded joints are constantly leveled by the pump integrated in the monitoring device. The pressure detector switches on the pump when a minimum pressure is reached and switches it off when a maximum pressure is reached.
For manufacturers of semiconductors, pharmaceuticals and biotechnology products, indoor air quality is critical. In these environments, "cleanrooms" monitor the air for particle and dust contamination. Unlike gas analysis, a particle counter measures the size and quantity of the contamination - it makes no identification. Measurement is made through observing the scattering of a laser beam as the sample passes through it. Essential for this application is a constant and pulsation free flow, in addition to the ability to control the flow easily.
