Routine calibration of mass spectrometers is required for optimal performance. Our new calibration solutions for Thermo Scientific Mass Spectrometers are ready-to-use liquid formulations for quick and easy instrument calibration.
Calibration of Thermo Scientific Ion Trap and Orbitrap Mass Spectrometers is required for proper instrument performance. These high-quality calibration solutions are for regulated environments and busy laboratories and avoid time-consuming reagent preparation. Reagents are provided in high-purity Teflon*-coated containers tested rigorously to provide the highest batch-to-batch reproducibility (Figures 1 and 2).
Figure 1. Representative mass spectrum for the Thermo Scientific Pierce LTQ Velos ESI Positive Ion Calibration Solution. N-butylamine, caffeine, Met-Arg-Phe-Ala (MRFA) and Ultramark 1621 are used to calibrate Thermo Scientific LTQ Velos Ion Trap and Orbitrap Mass Spectrometers in the ESI positive ionization mode. The N-butylamine is included to extend to low mass calibration range.
Thermo Scientific TSQ Mass Spectrometers are calibrated with multimers of tyrosine (Tyr1, Tyr3, Tyr6). All of the components of this mixture are prepared from the highest purity raw materials and are stored in inert Teflon-coated containers (Figure 3).
The Thermo Scientific Pierce LTQ ESI Positive Ion Calibration Solution is a mixture of highly purified ionizable molecules specifically designed for positive mode calibration of Thermo Scientific ion trap and orbitrap instruments.
