Savant Instruments - RVT405DDA-120
RE: Savant Instruments - RVT405DDA-120
5 Answers ECD/FID - I have a flame, I have flow through the column. (Bubbles at the detector end of the column.) Although I am not sure of the flow rate, Chemstation indicates that part is OK. I can "short" the detector with a piece of metal and the signal goes to 830,000. The base signal is only between 1 and 2. With my set up, I normally see at least 50. According to the software, the detector achieves temperature. I have changed columns. The last one installed is a brand new column. My syringe is injecting sample. I get no peaks. I get noise and some elevation of the signal (up to 8 or 10) right after injection but no peaks. Prior to having this issue, I replaced the inlet weldment. I had some issues getting the flow through the column reestablished after that replacement. But, by replacing an o-ring, I was able to obtain the proper pressure and flow as indicated on the Chemstation. Any guidance would be greatly appreciated.
