Internal quality control, method monitoring and quality control charts
Internal quality control (QC) – what’s that? You routinely perform laboratory analyses, but do you know whether your method also generates permanently reliable results? Yes of course, the method was validated once a long time ago, but since then...? Can you make a statement about the stability of the method? If such questions don't sound entirely unfamiliar, we’d like to introduce a tool today that precisely addresses this issue.
