Positive ion calibration solutions are mixtures of highly purified ionisable molecules specifically designed for positive mode calibration of ion trap and orbitrap instruments.

• Mass spectrometry grade reagents in a non-leachable container
• Load the mass reference standard into a syringe and inject into the instrument

It 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.
