Inquiry (采购产品): kirk.farrell@conocophillips.com Sir/Madam, We currently use a Buck HC-404 total hydrocarbon analyser for analysis of produced & re-injection waters on an offshore gas platform in the Timor Sea. We are trying to set up the analyser utilising a 100mm cell for analysis of oil in water to a level of <5ppm. The solvent we are currently using is Horiba S-316 (chlorotrifluoroethylene telomer/polychlorotrifluoroethylene). The problem we are facing is that we are unable to zero our instrument with the 100mm cell & S-316 solvent, and as such am unable to produce a working calibration curve for low range concentration of oil in water. The lowest blank reading we are able to obtain is 0.850 ABS / 18.5% T (ABS 0-2 range setting). I have tried reverting to tetrachloroethylene solvent, (once again with a 100mm cell), and have encountered the same difficulties. My question to you is - would replacing the lamp within the analyser solve our problem, or is the HC-404 only suited for use with Freon as the solvent? Could you please respond as a matter of urgency, as this issue is impacting on our continued operations.
