Metrohm is offering the Particle-Into-Liquid-Sampler (PILS), which can measure particulate pollutants several times an hour.
When used in combination with a Metrohm ion chromatography system, it can detect and quantify inorganic ions such as ammonium, nitrate, sulphate and chloride, with a cycle time of between five and 20 minutes depending upon the application.
The PILS system uses small quantities of steam to form water droplets on individual aerosol particles.
The water droplets containing the dissolved aerosols can then be captured and analysed by ion chromatography.
The instrument can be operated unattended for up to 20 days depending upon the volume of reagents and size of denuder and can take samples every five minutes.
The current method used for analysing airborne particulates is filter sampling.
The filters collect the aerosol particles usually over a 24-hour period and the results are reported as daily averages.
The PILS system from Metrohm UK is an effective method of producing real-time measurements for assessing air quality.
High-time resolution means more information can be gathered and trends and cycles can be observed.
Applications where the PILS system can be used include: indoor air-quality monitoring, ambient air-quality monitoring, tunnel monitoring, waste transfer and landfill-site monitoring, stack-emissions monitoring, and for protecting employees from emissions.
Metrohm UK offers a direct online on-site analysis using well-established techniques and without the need for manual sample preparation.
In combination with an ion chromatograph it is possible to determine the following species: cations (Na+, NH4+, K+, Ca2+ and Mg2+) anions (Cl-, NO3-, NO2- and SO42-) organic acids (acetate, formate and oxalate) and LOD: depending on ion ~ 5-100ng/m3 (250ml loop).
The price of the system includes full installation and training by a Metrohm applications chemist.
The PILS and IC systems are fully supported by a team of UK-based engineers.
