Dear all list users, We are looking an application to measuse VCM in PPM/PPB level in water i.e. hot water (50 to 70 C) passing through the PVC pipes. The pipes will be stored with water fort some duration at specified temperature and will be analyzed for any residual VCM present. We have the following querries : 1) Which type of Analyser is best suitable for measuring the same ? We are interested to know which principle of analytic measurement e.g. UV Photometric or IR analyser, Gas or Liquid Chromatography can be applied & which is the best suitable from principle point of view ? 2) Is anyone having this application in use ? Which type of analyser is used & how much reliable it is ?
