Highlights from this day

adelaide_assay — i was wrong about tailing factor. it is usually the injection or the pH, not the column, still working it out 18:52
adelaide_assay — coming back after 18 months, what changed in how you read these 18:56
VialBot — Channel stats, last 30 days: 128 messages from 25 members. 18:57
