Tips & Tricks: GPC/SEC How to Get a Stable Baseline
Author(s)Daniela Held
A stable baseline is a prerequisite for precise, accurate and reproducible GPC/SEC analysis, especially for samples with a broad molar mass distribution. Baseline problems can include drift, wander (long-term noise), noise/spikes (short-term noise), as well as positive or negative system peaks.
