Soil and water pollution can come from many areas, including acid rain, pesticides, landfill, raw sewage, and industrial waste. Analytical procedures include LC/MS and GC/MS.
HiQ instrument purge and carrier gases will be required along with environmental compliance mixtures including VOC and BTEX calibration standards.
Environmental measurement can be achieved in many ways. Air samples can be collected using sample bags or containers and analysed using gas chromatography. Continuous Emission Monitoring systems (CEM) is used by many facilities to measure specific pollutant emissions.
In all areas, a wide variety of pure gases and calibration gas mixtures are required. In addition, many of these gas mixtures must be certified accordingto international standards. Linde is able to meet your requirements for such pure gases and calibration gas mixtures.
