volatile organic compounds (VOCs) OSB SERVICES/OSB LAB      

   -Indoor Air Quality
   -Emission Sources


OSB Lab started testing for volatile organic compounds (VOCs) in 1995. Based on previous experience, the partner chemists of the firm determined that the potential of VOC analysis as an indicator of air quality had not been developed adequately. Other laboratories were reporting target lists founded in water and soil pollution characterization. OSB Lab decided that air quality assessments required a custom approach defining each individual situation with its own parameter list. Methods were established to suit real air quality issues. The OSB team includes chemists, environmental scientists, air quality consultants, industrial hygiene and building science professionals.
