Product Description:

SpheriCal® is a dendrimer-based MALDI-TOF MS calibration standard providing 4 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 kit 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.


The SpheriCal® Ultimate Kit covers a calibration range of 500 – 30,000 m/z and contains, 


- 1 x vial of SpheriCal® Peptide Low

- 1 x vial of SpheriCal® Peptide Medium

- 1 x vial of SpheriCal® Peptide High

- 1 x vial of SpheriCal® Protein Low

- 1 x vial of SpheriCal® Protein Medium


The standards are available as SpheriCal® Neat or SpheriCal® Mix. SpheriCal® Neat is provided without any matrix or cation source and, because the SpheriCal® calibration standards exhibit 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.
