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.

Features of LTQ ESI Positive Ion Calibration Solution:

Strong peaks—mixture of caffeine, MRFA and Ultramark 1621 in a solution of acetonitrile, methanol, and acetic acid
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

The Pierce LTQ ESI Positive 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 LTQ ESI Positive 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.

The LTQ ESI Positive Ion Calibration Solution can be used to calibrate the LTQ series, the LTQ Orbitrap series, the LXQ, LCQ FLEET and the Exactive Mass Spectrometer instruments.
