LTAR202507170724S18S19BGC sequence had a vial order issue. There were vials submitted out of order for Series 18 such that I ran them in sequence 31, 32, 36, 33, 34, 35, 37, 39, 38, 40, 41 for Round “A,” but then forgot to make the same change for Round “B.” So Round B was entered in the sequence as running in consecutive order (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, etc.). Please refer to data sheets for clarification on this. I will change the Round “B” labels in the Excel results file to properly match Round “A.” |

GC run LTAR202507030710S16S17BGC (and version “B”) notes: Analysis setup and computer froze overnight, prior to completing first set of standards - i.e. system ran through all methane analyses, but only recorded results through standard vial 13 or so. Therefore, the system was rebooted and rerun at that point. At rerun, initial few standards looked to be contaminated - may use initial run for 1st standard set and “B” run for sample and final standard results. Sampling notes - series 17 vials submitted with note that vials 141 and 117 were swapped. These were run in swapped order on the GC (i.e. 116, 141, 118.. then 140, 117, 142… etc.) Additionally, sample vial 93 from series 17 was dropped and broke. The vial was replaced in the run, but just contained lab air. |
