Solvents and Other Organic Chemicals
We provide analysis by gas chromatography (GC) for VOCs in workplace samples, other air samples, soil, fluids and in headspace. We undertake quantitative analysis for total VOC levels and a wide range of specific substances provided we can obtain calibration standards such as white spirit or resin acids. We use high performance liquid chromatography (HPLC) to analyse for isocyanates, hydrazine, formaldehyde and other aldehydes.
Where there is uncertainty about the compounds present, we can use gas chromatography in combination with mass spectrometry (GC-MS) to identify the major substances and follow this up with quantitative analysis, where appropriate. This is particularly helpful where there is an indoor air quality issue such as an “unknown smell” that is giving rise to anxiety about possible health effects.
We also use the GC-MS to analyse for Freons (refrigerant gases), polyaromatic hydrocarbons (tars), polychlorinated biphenyls (PCBs), acetic anhydride, organic lead, some pesticides and other specific substances such as some lubricants.
We have UKAS accreditation for frequently requested analytes: benzene, toluene, ethyl benzene, xylene, chlorinated solvents, formaldehyde, resin acids and isocyanates.
Our chemistry team will be pleased to discuss your particular sampling and analytical requirements and help you to find the most cost effective approach to investigating workplace exposures or air quality issues. We can provide appropriate sampling media and pumps for hire, if required.
