| FMA RMT-200 05-0010 | 2014-05-20 | Lab none | Damaged | Lab none | After being moved, but not treated roughly, the analyzer stopped reporting CH4. The ring time is variable from 2 to 20usec and the spectrum looks odd. Cleaning the mirrors made no difference. LGR thinks there is something wrong with the laser. At this time there is an 8 week wait for repairs and a minimum cost of 00 for cleaning and calibration - any repairs would be an additional cost. We don't need this analyzer right now and will wait to repair it. |

| LI-6400 PSC-0785 | 2007-02-20 | Factory | Calibration | Factory | Sent to Licor to check for flow restriction in chemical tubes, test PAR IN stability and calibrate light source. Findings: No CO2 source cover sent. In checking for blockages in the chemical tubes, initially there were none, so I had them rebuilt. In that process we discovered that the small tubes in the bypass valve had been pinched flat. Most likely, they had been left in either the scrub or bypass position for an extended period of time, causing them to be flattened-shut. We replaced them. It is a good idea to out the valve in the center, most relaxed, position for storage. The light source is stable and I could not get it to do anything unusual, even with lots of cable stressing/wiggling. |

| LI-6262 IRG3-1079 | 2016-09-09 | Lab none | Calibration | Lab none | Calibrated in differential mode for double check of secondary standard. Ambient temperature was 24.37C, pressure was 100.54kPa. Using Zero air (400psi) and god bottle 421.22ppm CO2 (400psi). Flowing zero air in both sample and reference CO2 0.22ppm - adjusted to 0.06 H2O 0.25 - could not adjust - railed Flowing zero air in reference and god bottle in sample CO2 = 420.54ppm adjusted to 421.26ppm. Flowing zero air in reference and secondary standard in sample, I recorded serial data with Hyperterm and took an average of 100 points. The new tank is 405.83ppm I accidentally changed the H2O span. I reset to approximately the same value but did not check it with the dew point generator. |
