Reagents for Mass Spectrometry


Positive and negative ionization calibration standards and matrices for matrix-assisted laser desorption ionization (MALDI), electrospray ionization (ESI) and other forms of proteomics analysis with mass spectrometers.


Peptide standard from HeLa cell tryptic digest for mass spectrometry quality control and method calibration, rigorously tested and highly characterized for quality and lot-to-lot consistency. 

15 synthetic heavy peptides mixed in equimolar ratio to test and calibrate reverse-phase liquid chromatography (LC) and mass spectrometry (LC-MS) equipment. 

Evaluate mass spectrometer performance using this exact solution of reserpine (MW 608.68g/mol; CAS 50-55-5), supplied at a concentration of 100pg/uL in 50 percent isopropyl alcohol and packaged in convenient screw-cap vials. 

A mixture of highly purified ionizable molecules designed for negative mode calibration of LTQ mass spectrometer instruments. 

A mixture of highly purified ionizable molecules designed for positive mode calibration of LTQ, LTQ Orbitrap, LXQ and LCQ FLEET mass spectrometers. 

A mixture of highly purified ionizable molecules designed for positive mode calibration of LTQ Velos, LTQ Orbitrap and other mass spectrometers. 

A mixture of high purity, ionizable components specifically designed for positive mode calibration of Triple Stage Quadrupole (TSQ) mass spectrometers. 

Highly purified, recrystallized CHCA, DHB and SA reagents in single-use tubes for mass spectrometry by matrix-assisted laser desorption ionization (MALDI).
