Agilent, 5190-0583, 10-peptide standard, 71 µg, lyophilized, in a 2 mL vial

The Agilent 10-peptide standard is a lyophilized mixture containing a total of 71 µg of ten peptides in a 2 mL vial. It supports system suitability evaluation for reversed-phase liquid chromatography and peptide-separation workflows. A multi-peptide mixture produces a series of chromatographic responses that can reveal changes in column selectivity, retention, peak shape or overall system performance. The reagent is particularly useful when checking a reversed-phase peptide method before analysis of complex samples or when comparing performance after replacing a column. Each constituent has a distinct molecular structure and retention behavior; the mixture is therefore more informative than a single-analyte injection for examining separation quality. Reconstitute the lyophilized material in an appropriate solvent and volume for the validated method, using the corresponding certificate of analysis for lot-specific reference information. It is a chromatography standard, not a clinical test kit or standalone calibration instrument.
