CHNS Mass Report (Standalone Test)

The CHNS Mass Report is a standalone elemental analysis designed to determine carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) content in a sample. For peptide samples, CHNS analysis can be used as an independent approach to assess net peptide content.

Unlike HPLC-based amount determination, CHNS analysis is based on combustion of the sample rather than dissolution. This can help avoid solubility-related limitations that may affect some chromatographic measurements.

About CHNS Analysis

CHNS elemental analysis determines the proportions of carbon, hydrogen, nitrogen, and sulfur present in a sample. During analysis, the sample is combusted and the resulting elemental composition is measured.

For peptides with a known elemental composition, these data can be used to evaluate the actual peptide content of the sample independently of chromatographic purity measurements.
