It emphasizes HPLC's precision and reliability in testing vitamin content in supplements. The piece explains why HPLC is considered the gold standard for ensuring the quality and potency of Vitamin D3 products. https://www.123articleonline.com/articles/1444651/why-is-any-viable-amino-acid-technically-ninhydrin-positive-substances Ninhydrin reacts with primary and secondary amino groups in amino acids to form a colored complex, typically purple or blue ("Ruhemann's Purple"). This reaction helps detect and quantify amino acids in various samples, making Ninhydrin essential in methods like chromatography. The color intensity correlates with amino acid concentration, aiding both qualitative and quantitative analysis in analytical labs.
