Did you know Particle Technology Labs began as a testing service for companies needing to meet EPA environmental safety standards? While we are most known today for our testing for the pharmaceutical industry and our commitment to cGMP quality assurance regulations, some will be surprised to learn that the company’s early services were in testing environmental emission and water filtration samples. Now, almost 30 years later, we still assist companies in these industries including some of those first clients who are still with us today!
Testing for PM10 and PM2.5
The founder of Particle Technology Labs, Richard Karuhn Sr., started the company by providing analysis of stack emission samples for PM10 and PM2.5 in 1992. He not only tested them – he spent time collecting them as well!
What do PM10 and PM2.5 stand for? Glad you asked. PM is an abbreviation for “particulate matter.” PM10 or PM2.5 is the particulate matter in an emission sample that is less than 10 or 2.5 micrometers respectively by mass. These sizes are of interest to the USA Environmental Protection Agency (EPA) as particles in this size range are not easily filtered out by the nasal passages nor impact the back of the throat for removal when we breathe. Particles less than 10 micrometers will enter the lungs and can cause both acute and chronic respiratory issues. Factories, power plants, and similar types of companies are required to monitor and control their emissions for these particles or risk expensive fines and/or production shutdowns.
