Professional VOC testing involves strategic air sampling throughout your building using advanced analytical equipment to measure specific compounds and concentration levels. Testing typically takes several hours for proper sample collection, with laboratory analysis using gas chromatography and mass spectrometry for accurate compound identification. Results are usually available within 5-7 business days and include detailed reporting that explains findings and provides actionable recommendations. The process is non-disruptive to normal operations and includes source identification to pinpoint contamination origins. Professional analysis distinguishes between different VOC types and evaluates health risks for building occupants.
