SpheriCal MALDI: Neat Peptide Low (PFS-0001)

SpheriCal® is a dendrimer-based MALDI-TOF MS calibration standard providing multiple monodisperse mass signals per kit for efficient, highly accurate calibration. By combining excellent long-term stability with evenly-spaced calibration points, SpheriCal® helps users increase the frequency and quality of their calibrations.  With a shelf life of years and each vial offering at least 100 calibrations, SpheriCal® offers a reliable and accurate calibration across a large mass range, without the shelf-life and storage issues associated with protein or peptide-based systems.

SpheriCal® Peptide Low covers a calibration range of 250 – 1,600 m/z with 6 calibration signals, expanding the calibration range for the detection of lower mass species.

SpheriCal® Neat is provided without any matrix or cation source.  Due to SpheriCal®’s unusually broad solvent and matrix compatibility, this product can be used with a wide range of sample preparation conditions, though ionization is preferred with alkali cations. The freedom of this product line will enable you to explore your own calibration protocols for optimization purposes.
