Fast and Accurate Peptide Quantitation using the Direct Detect® Spectrometer

The Direct Detect® spectrometer, an infrared (IR)-based spectrometry system working in combination with a novel membrane technology, quantifies amide bonds, which are intrinsic to all proteins and peptides. Application of peptides in solution onto the membrane enables fast drying and rapid and inexpensive quantitation by the Direct Detect® system, eliminating the need for time-consuming amino acid analysis (AAA).
