The Thermo Scientific Pierce ESI Negative Ion Calibration Solution is a mixture of highly purified ionizable molecules designed for negative mode calibration of Thermo Scientific LTQ series mass spectrometer instruments.
The Pierce ESI Negative Ion Calibration Solution is a ready-to-use liquid formulation ideal for quickly performing the routine calibration required to maintain the robust performance of Thermo Scientific Mass Spectrometers. The ESI Negative Ion Calibration Solution is manufactured at an ISO 9001 facility and each lot is quality controlled with strict specifications. The stable solution is provided in a leak-proof, high-purity PTFE bottle.
- Strong peaks – mixture of SDS, sodium taurocholate and Ultramark 1621 in a acetonitrile/methanol/acetic solution.
- Ready-to-use – load the mass reference standard into a syringe and inject into the instrument
- High-purity – mass spectrometry grade reagents in a non-leachable container
- Stable – store at room temperature for more than one year
The ESI Negative Ion Calibration Solution can be used to calibrate the LTQ series, LTQ Velos series, the LTQ Orbitrap series and Exactive Mass Spectrometer instruments.
