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 Medium covers a calibration range of 500 - 3,500 m/z with 6 calibration signals, expanding the calibration range for the detection of lower mass species.
SpheriCal® Mix is provided with matrix and counter-ion in optimized ratios to enable quick and time-efficient calibration with DHB as matrix.
The DHB Mix is not in stock but can quickly be re-stocked upon request. The shown spectra were collected with DHB as matrix. Upon order, the intesities of the lower molecules will be adapted.
