AIR EMISSIONS & COMPLIANCE MONITORING SERVICES

VOLATILE ORGANIC COMPOUNDS (VOC’s) are organic chemicals that have a high vapour pressure at ordinary room temperature. Their high vapour pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air. Unergy implements US EPA method 18 in conjunction with Apex instruments specifically designed for VOC sampling. 

ISOKINETIC AND NON -ISOKINETIC SAMPLING

The use of US -EPA methods are used to measure and determine particulate matter (PMs dust), metals, semi -volatile organic compounds, dioxins (PCDD), furans (PCDF) and gas emissions measurements of CO, CO2, SO2, SO3, NOX (N02), NH3, HF, HCI (HCL), H2S

ENVIRONMENTAL SAMPLING

Unergy can sample for a variety of pollutants from chemical holding tanks and or various industrial processes implementing various NIOSH and OSHA methods. Samples are drawn through sorbent tubes and filter configurations and sent to an ISO 17025 accredited laboratory for analysis.
