Stopped measurement and closed software. Edited Table 1 of the SS sequence to reverse the order. Previous order was an hourly cycle of 6 SS, 10 min each 0.2, 0.3, 0.4, 0.5, 0.6, 1.0 New order is the reverse (10 min at each still): 1.0, 0.6, 0.5, 0.4, 0.3, 0.2. I have done this to try to improve the OPC temperature adherence – during the previous cycle, the transition from 1.0 to 0.2% doesn’t provide enough time for the OPC temperature to reach setpoint, creating a condition where the droplets may be evaporating in the OPC before detection. I have been advised that this may be improved by reversing the sequence (or doing a pyramid sequence, which is not ideal). | |

Main repairs were: - to remove the contaminated tubing between the column solenoid pump, cold trap solenoid pump, and drain bottle. I also changed the column solenoid pump but in hindsight I don& 39;t think that was actually faulty. - The nafion humidifier tube was dry and coiled up inside the humidifier chamber. I had to really soak and stretch it to get it long enough to reinstall - The sheath flow filter and frit filter were saturated. I replaced the sheath flow filter and dried out the frit filter in the oven - on reassembly I had a leak or leaks. I tried almost all fittings as I had had most off. the final, and probably original leak i had was the connection to the tee at the upper side of the frit filter that goes to the sheath flow differential pressure sensor. The tubing had split slightly. I trimmed the end of the tube and remade the connection. All zeros!!!! | |

This will have affected the SMPS, and CPCs. It is possible that it will have affected the.nephelometer and CCNC. It is possible, but I think unlikely, that it also affected the ozone and greenhouse gas system, depending on the interactions in the manifold and sample lines. | |

Checked DFU on the CPC and it quickly went to zero where it remained steady. Desiccant tube checked OK. Removed valve from above DFU and discovered it was in the wrong way (flow in the wrong direction compared to the DFU). Need to check. Decided to delay the OPC clean the bisque disinfecting for next time and practice and document on the CSC CCN which is about to go back to DMT anyway. Removed the capillary, sampling inlet manifolds (x2), and flow valve for cleaning in the ultrasonic. Exchanged the nafion for a new one. Checking pressure transducer against the one on the port side rack (after disconnecting from the manifold). CCN: 1015.7 hPa Barometer: 1016.4 hPa OK! Leak check - passed! Approx 0.1 mbar increase per second. ===================== Flow cal: Check before doing anything - 502.1 ccm (n=11) FlowCal tab values before doing anything: Sample flow y-int = -117.218 Sample flow Slope = 58.6627 Sheath flow y-int = -1557.34 Sheath flow slope = 689.24 Abs pressure y-int = 107 Abs pressure slope = 222.53 Set sample flow y-int and slope to 0 and 1, respectively and blocked the sheath flow path. Tried to do the sample cal and there was no flow. Checked capillary for condensation but it was OK. Checking flow directly into the top of the column, and still nothing. Suspect some issue with the nafion (as suggested in manual). Removing the nafion - I possibly kinked it when pushing it through accidentally. Removed the whole thing for inspection - compared to a new one, its lost a lot of colour, and it does indeed have a kink. Replacing with a new one. The new one was soaked in milliQ water in a clean ice-cream container for 10 minutes prior to insertion. Seems to have come good again. Flow calibration results: Sample flow y-int = -118.03 Sample flow slope = 59.102 Sheath flow y-int = -1435.37 Sheath flow slope = 646.72 Turned manual override off to verify flows. Sheath flow software read and gilibrator read within about 2 ccm (455 ccm) - OK Sample flow software read and gilibrator read within about 2 ccm (43 ccm) - OK Flow ratio 10.5 - OK | |
