Assay
Quantification of an analyte against a material of known content. Distinct from area percent, which compares peaks within one chromatogram.
Related terms
- Area percent
- Purity expressed as the main peak's integrated area divided by the total integrated area of all peaks, times 100. A relative quantity. It is not a concentration and not a content.
- Reference standard
- A material of known content used to quantify an analyte. Absent for most research peptides, which is why content is rarely measured.
