Non-client sample

A non-client sample is a type of quality control (QC) sample that is different than other QC sample types in that it is, simply, a regular sample. Many programs require that certain data be reported from the analysis of non-client samples that were prepared or analyzed with project-specific samples. This is often done to verify run sequences and to ensure that certain QC samples were analyzed at an appropriate frequency. The actual analytical results would seldom be reported.
