Both the Pierce FlexMix Calibration Solution and Pierce FlexMix Calibration Solution for Auto-Ready Mass Spectrometers have the same 16 components and produce the same spectra. However, the Pierce FlexMix Calibration Solution for Auto-Ready Mass Spectrometers has a different storage solution: LC-MS grade acetonitrilie 87% (v/v) and LC-MS grade water 13% (v/v). The FlexMix Calibration for Auto-Ready Mass Spectrometers is designed to be used only in mass spectrometer instruments with autocalibration feature, such as Orbitrap IQ-X Mass Spectrometer using Orbitrap Tribrid Series 3.5 Instrument Control Software (or later).
