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 Mix Peptide Low (m/z 500 - 1,000)
ii.SpheriCal Aqua Mix Peptide Medium (m/z 1,000 - 2,500)
iii.SpheriCal Aqua Mix Peptide High (m/z 2,500 - 5,200)
iv.SpheriCal Mix Protein Low (m/z 5,200 - 11,000)

SpheriCal Aqua Neat: ideal for water-based systems.

SpheriCal Aqua Mix is ideal for calibration with aqueous systems commonly used in life sciences. As calibration standard, matrix and counter ion are pre-mixed in optimized ratios, SpheriCal Aqua Mix dramatically expedites sample preparation for calibration in minutes. SpheriCal Mix is pre-formulated with DHB, a commonly used matrix in the analysis of peptides, proteins, phospholipids, nucleotides and polar synthetic polymers. Each vial of SpheriCal Aqua Mix contains sufficient calibration standard for over 100 calibration spots.
