Scientific Instrument Services introduces a new calibration mixture for electrospray ion sources. This mixture covers a wide mass range from 195 to 1922. It is already in the proper concentration to run directly in an electrospray source without dilution. The mixture consists of caffeine, MRFA (met-arg-phe-ala) peptide, and per-fluoroalkylphosphazine.
