Fine Particle Sampler FPS-4000

The Fine Particle Sampler FPS-4000 is the most comprehensive dilution and sample conditioning system commercially available in the world. Applications range from automotive exhaust and combustion flue gas measurements to laboratory and nucleation studies. The FPS-4000Fine Particle Sampler has the capability of changing the dilution ratio and dilution temperature, and it enables sampling from high or low temperatures and pressures.

This makes it suitable for sampling from pre- and post after treatment or flue gas cleaning devices, with the ability to always produce a high quality sample to the measurement instruments. In addition, the option to use cooled dilution makes it possible to run high accuracy nucleation studies with the FPS-4000.

The operation principle of the FPS-4000 is based on combining perforated tube dilution with ejector dilution, where the perforated tube dilution can be operated heated or cooled. Both dilution stages have an adjustable dilution ratio, and the dilution ratio of the whole system is calculated in real-time and automatically corrected for temperature and pressure effects. In addition, all measured temperatures, pressure and calculated dilution ratios and sample flows are saved to a data file for easy access after the measurements.
