TSP Monitoring
Total suspended particulates (TSP) is the measurement of particles in the air from as low as 0.1um up to as high as 50um. It is an older method of monitoring when compared to measurements of PM1, PM2.5 and PM10 which are adopted by many health authorities, regulatory bodies and organizations these days. The 50um upper TSP limit is defined by the Australian EPA and is listed on their web site.
NO LIGHT SCATTERING DEVICES CAN MEASURE TSP
This type of monitoring can only be achieved by using a high volume sampler. Such samplers have flow rates of hundreds of litres per minute and have a much better ability to properly sample larger sized particles. Companies cannot use any light scattering devices for the measurement of TSP. The Australian EPA has not approved the use of any light scattering devices for TSP measurements, however does support the use of high volume samplers.
