Description

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 Neat Peptide Low (m/z 500 - 1,600)
ii. SpheriCal Neat Peptide Medium (m/z 1,600 - 3,500)
iii. SpheriCal Neat Peptide High (m/z 3,500 - 7,500)
iv. SpheriCal Neat Protein Low (m/z 7,500 - 15,000)
v. SpheriCal Neat Protein Medium (m/z 15,000 - 30,000).

SpheriCal Neat: unprecedented freedom for the user.

SpheriCal Neat is provided without any matrix or added cation 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. The freedom of this product line will enable you to explore your own calibration protocols for optimization purposes. Each vial of SpheriCal Neat contains sufficient calibration standard for over 100 calibration spots.
