Noticed an issue with inconsistent check standards on LTAR202504100417S4S5BGC run. Some checks made before, some after, a nitrogen tank change-out. (N2 used in making up standards.) High standards, with no N2 addition, appear to be fairly consistent across the last 3 sample runs. A separate standard/check std run was completed after the LTAR run to test for this issue. This standard run would likely be better to use with the LTAR run. Standard run was STD_TEST20250424BGC.

Prepared 1M KCL.

LTAR202504100417S4S5BGC sample run on GC had vials submitted out of order on trays. All samples were run on GC in numerical order. Samples submitted out of order as follows: …4, 5, 9, 7, 8, 6, 10, 11, 12… and …135, 136, 140, 137, 138, 139, 141, 142….

BCSE202503310416S2S3BGC sample run on GC had a small set of samples submitted out of order on the trays. All vials were run on the GC in numerical order. Vials out of order on trays as follows: ….56, 57, 59, 58, 60, 61, 62, 63…..
