| FMA RMT-200 05-0010 | 2012-01-25 | Twitchell Rice | Calibration | Twitchell Rice | With the new external filter I calibrated the LGR. The cal tank has <200psi of 3.276ppm CH4. Last calibration was Dec 20, 2011.
Pre Cal: 8:49PST, 29.61C, 156.07Torr, 13.871usec, 3.282ppm, 1Hz The first try at calibration failed somehow ending in a value (3.317ppm) farther from the span gas. A second calibration seemed to work fine and ended up right on. When I left the LGR read 9:56PST, 23.93C, 153.81Torr, 13.060usec, 10Hz, 2.311ppm |
| FMA RMT-200 05-0010 | 2011-12-18 | Twitchell Rice | Calibration | Twitchell Rice | All was running. The LGR read:
9:04PST, 31.36C, 97.41Torr, 13.973usec, 10Hz, 2.964ppm I calibrated the LGR with secondary tank with 3.276ppm CH4 at 250psi. Last cal was 2011-11-22 Pre cal: 9:12PST, 30.18C, 124.54Torr, 13.972usec, 1Hz, 3.200ppm Pressure was a little low but okay. After cal the LGR read 3.271ppm. I adjusted the bypass valve to bring the pressure to 146Torr in high flow mode. I returned the LGR to 10Hz before leaving. |
| FMA RMT-200 05-0010 | 2011-11-22 | Twitchell Rice | Calibration | Twitchell Rice | We calibrated the LGR with a 3.276ppm tank with 400psi. Last cal was Oct 10, 2011.
9:56PST, 9.53C, 156.07Torr, 14.341usec, 1Hz, 3.357ppm After cal it was right on. When we left it was back in high flow at 10Hz and pressure was about 141Torr, I did not adjust the bypass valve. |
| FMA RMT-200 05-0010 | 2011-10-27 | Lab none | Installed | Twitchell Rice | Installed to replace sn 08-0114 since in slow flow mode there was zero flow. |
| FMA RMT-200 08-0114 | 2011-08-12 | Twitchell Rice | Calibration | Twitchell Rice | The LGR pressure was really low 89.28 and in slow flow it was even lower. I checked the external 2um filter and it seemed clean. I checked the internal 2um filter and it was completely stopped up. I replaced it with a cleaned one. I blew the replacement filter clear with the cal tank but it still brought the ring time down after I got it all back together. The pressure was better and I had to close down the bypass valve to bring it in range.
9:00PST, 24.16C, 144.56Torr, 13.300usec, 10Hz, 1.831ppm The low flow pressure was still a bit low during calibration: 9:06PST, 24.05C, 125.31Torr, 13.302usec, 1Hz, 3.270ppm The calibration was almost right on with the 3.267ppm tank at 650psi. Last cal was July 1, 2011. The pressure fell to 111.7 by the end of the calibration. I also replace the 40um filter strainer. It was very dirty and had some spider parts in it. Before leaving the LGR read: 9:34PST, 24.55C, 144.81Torr, 13.291usec, 10Hz, 1.827ppm |
| FMA RMT-200 05-0010 | 2010-05-13 | Twitchell Rice | Calibration | Twitchell Rice | The LGR was reporting:
8:27PDT, 22.89C, 120.58Torr, 16.781usec, 10Hz, 1.858ppm I adjusted the bypass valve to correct the pressure. I calibrated the LGR with 3.276ppm tank with 700psi. Last cal was March 22, 2011 Precal: 8:47PDT. 24.11C, 156.50Torr, 16.776usec, 1Hz, 3.290ppm After cal 3.276ppm Before I left the LGR read: 8:52PDT, 24.49C, 150.77Torr, 16.774usec, 10Hz, 1.883ppm |
| FMA RMT-200 05-0010 | 2011-03-22 | Twitchell Rice | Calibration | Twitchell Rice | Pre cal: 8:42PST, 17.16C, 156.57Torr, 17.042usec, 1Hz, 3.347ppm � about 70ppb off.
Post cal: 3.277ppm Before we left the LGR read: 8:55PST, 17.42C, 149.22Torr, 17.068usec, 10Hz, 2.176ppm |
| FMA RMT-200 08-0114 | 2010-12-02 | Twitchell Rice | Calibration | Twitchell Rice | Pre cal:
7:43PST, 24.90C, 142.80Torr, 16.064usec, 1Hz, 2.660ppm - off by 616ppb a lot. Post cal CH4 was 3.263ppm And back in operation after adjusting the bypass valve because pressure was too high: 7:53PST, 23.33C, 143.96Torr, 16.089usec, 10Hz, 3.266ppm |
| FMA RMT-200 08-0114 | 2010-09-08 | Twitchell Rice | Calibration | Twitchell Rice | I adjusted the bypass valve. When Frank arrived we did a calibration. Last cal was done on Aug 6, 2010. The field tank is 3.276ppm CH4
Precal: 9:52PST, 25.54C, 111.2Torr, 16.112usec, 1Hz, 3.377ppm Low flow pressure seems low here too but I did not check the filters. Being 100ppb off seems a lot, last cal uses a standard closer to 1.8ppm though. Post cal CH4 read 3.276ppm. When we left the LGR read: 10:02PST, 25.49C, 144.34Torr, 16.080usec, 10Hz, 1.840ppm |
| FGGA 09-0010 | 2010-06-22 | Twitchell Rice | Calibration | Twitchell Rice | Initial readings from the LGR were:
9:57, 29.18C, 129.50Torr, 13.902usec, 10Hz, 1.865ppm, 14819ppm, 385.91ppm I tried calibrating and notice very low pressure in low flow mode � 74.89Torr. I completed the calibration, but did not like it. I checked the exterior 2um filter and it seemed okay. I also checked the internal 2um filter and it seemed good as well. In checking the interior I noticed a loose connection. The connector that has to be disconnected to clean the mirror was left disconnected last time I cleaned the mirrors. I�m asking LGR what this connection does. It doesn�t look significant but after connecting it the pressure improved somewhat. And I did a second calibration. Precal: last cal June 3, 3.276ppm CH4, 433.0ppm CO2, 1800psi 10:54, 134.32Torr, 3.217+-0.003ppm CH4, 416+-2ppm CO2 Post cal: 10:57, 130.0Torr, 3.276+-0.002ppm CH4, 433+-1ppm CO2 Last readings from LGR: 11:02, 28.57C, 144.47Torr, 13.86usec, 10Hz, 1.888ppm, 15195ppm, 400.44ppm |

| FGGA 09-0010 | 2010-04-22 | Twitchell Rice | Calibration | Twitchell Rice | The LGR would not line lock CH4/H2O when power was restored. Initially the cell temperature was about 10C and I let it warm up to 18C with no lock and many restarts. Finally I called LGR and got their maintenance password to change line lock settings from 0.165 to 0.185 and this did the trick.

Cell Pressure=39.54kPa, Cell Temperature=27.98C, Ring Time=17.17usec 2nd standard at 0psi: CH4: 3.276ppm, CO2: 433ppm, H2O: 0ppm CH4 = 3.5032ppm -> 3.316ppm Offset: -0.227ppb CO2 = 448.8ppm -> 441ppm Offset: -15.8ppm Notes: External filter seemed plugged up, swapped it with cleaned filter before calibration. Values improved, but I still don't agree with cal tank. I think the very low pressure is a problem. Maybe the internal filter is plugged up. I will do some check in the lab and then possibly swap out the LGR. |
