WebDec 15, 2005 · By changing the inlet configurations of one of the monitors (adding a denuder, a Teflon filter, or both), the influences of positive and negative sampling artifacts were investigated. The positive artifact was found to be relatively large (7.59 μg/m 3 on average), more than 50% of measured OC, but it was practically eliminated with a denuder ... WebMay 29, 2024 · 3. Artifacts are variations introduced by non-biological processes. Sequencing involves a lot of chemical reactions, and changes in nucleotides that can seem like mutations are really introduced somewhere in the processing of the sample. That's what we call "sequencing artifacts".
