The presence of polyphenolic micronutrients in food is shown to be beneficial to humans health due to their powerful anti-oxidation properties. MetaSci’s Flavonoids Mix contains 40 flavonoids including flavonols, flavonones and chalcones that are commonly found in plants, foods and health supplements. The standard mixtures come as 0.2mM - 1.0 mM methanolic solution and are suitable to use with HPLC methods utilizing a standard C18 column and MS, UV or ELSD detector. Each mixture is designed to have 10 compounds highly resolved on a C18 column with no isobaric interference which makes it to work even on a low resolution MS. The standard mixtures can be used for peak identification, making calibration curves for quantification and making an in-house digital library of spectra.

Why digital libraries (NIST, METLIN, etc.) are not enough?
Every instrument yields an analysis result specific to its brand, build, methods and other parameters. Digital libraries only contain spectra resulted from the instrument of its producer and lose quality as it is used for other machines. To produce the most accurate result for each instrument, a lab should run physical standards on every instrument and on each when the methods or conditions (column, solvent, pH, etc) is changed.
