| LI-800 AKC-0479 | 2011-10-17 | Lab none | Maintenance | Lab none | I cleaned the bench. There was one black spec inside the bench and another on the source end. After cleaning, I was able to calibrate the IRGA.
Press = 1003mBar, Temp = 52.6C, Heater = ON, Filter = 0sec, span = 1000ppm. Several cycles of zero air and span CO2 410.49 seemed to bring it back into range. |

Flowing zero air in both sample and reference CO2 = 0.55umol/mol adjusted to zero. H2O = 0.0003 Flowing zero air in reference and god bottel in sample CO2 = 371.25ppm adjusted to 370.91ppm. Flowing zero air in reference and new secondary standard in sample, I wrote down 90 reading and made an average. The new CO2 secondary standard has 410.49ppm CO2. |
| FMA RMT-200 05-0010 | 2011-10-10 | Lab none | Calibration | Lab none | I calibrated the LRG with the god bottle and then used it to check two secondary standards. God bottel is 1.8978ppm CH4 and 350psi. Last calibration was 2011-08-23 using 3.276ppm CH4.
Precal: 9:32PST, 23.79C, 156.56Torr, 14.715usec, 1Hz, 1.855ppm Postcal the CH4 read 1.897ppm. The older secondary standard with 405.85ppm CO2 read 4.675ppm CH4 The newer secondary standard with 410.49ppm CO2 read 3.228ppm CH4 |
| FMA RMT-200 05-0010 | 2011-10-10 | Lab none | Maintenance | Lab none | No flow in low flow mode. The internal 2um after the pressure controller seemed okay. I disassembled the inlet tubing and fittings to get a 10um filter out from infront of the pressure controller. This was completely plugged. I rinsed it with degreaser and DI water and dried it by blowing air through it. Flow was better but still seemed low. I reinstalled the filter and reassembled the inlet tubing. Now is slow flow the internal pressure is 156Torr. |

| FMA RMT-200 05-0010 | 2011-08-16 | Lab none | Calibration | Lab none | See calibration log. I also set the time to local standard time and changed the serial settings to 115200. I left it in high flow and shutdown so it should boot correctly next time. |
| FMA RMT-200 05-0010 | 2011-08-12 | Lab none | Repair | Lab none | This analyzer was removed from the field because it would not boot. Connecting the hard drive to a computer running Knopix Linux I could see that the drive was full and deleted some of the data files. Then it would boot but the analyzer software would crash and kick out into the service shell. There I could see that a bunch of the *.ini files in the icos folder were zero length. LGR was able to email me a copy of these files and replacing them seemed to fix the problems. |
| LI-6262 IRG3-1079 | 2011-07-08 | Lab none | Calibration | Lab none | I calibrated the Li6262 in differential mode. I flowed zero air through a T into both the reference and sample cells at a flow just detectable on wetted lips. CO2 was low by about a 0.1 ppm CO2. I adjusted both CO2 zero and H2O zero. I then flowed 370.91ppm CO2 in air (god bottle) through the sample while leaving the zero air in the reference. The 6262 read 369.20+-0.05ppm. I adjusted the CO2 span to match the tank value. I tested the nearly empty 597.4ppm tank and it was true. I then test the new 400ppm CO2 in air tank and came up with a value of 405.85ppm and labeled the tank with this value. |
