General description

SpheriCal is a dendrimer-based MALDI calibration kit 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 MALDI-MS 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.

Mass ranges available:

i.SpheriCal Aqua peptide low (m/z 500 - 1,000)
ii.SpheriCal Aqua peptide medium (m/z 1,000 - 2,500)
iii.SpheriCal Aqua peptide high (m/z 2,500 - 5,200)
iv.SpheriCal Aqua protein low (m/z 5,200 - 11,000)

SpheriCal Aqua Neat: ideal for water-based systems.

SpheriCal Aqua is ideal for calibration with aqueous systems commonly used in life sciences, e.g., matrices DHB, HCCA and SA or solvents such as water and acetonitrile, although ionization is preferred with alkali cations. Each vial of SpheriCal Neat contains sufficient calibration standard for over 100 calibration spots.
