Answer:It is used for positive-mode mass spectrometer calibration.
Answer:The mixture contains caffeine, MRFA, Ultramark 1621 and n-butylamine in an acetonitrile/methanol/acetic-acid solution.
Answer:Compatible systems include LTQ Velos and Velos Pro, LTQ Orbitrap Velos and Orbitrap Velos Pro, Orbitrap Elite and Q Exactive instruments.
Pierce™ LTQ Velos ESI Positive Ion Calibration Solution is designed for positive-mode calibration of compatible Thermo Scientific electrospray mass spectrometers. The ready-to-use 10 mL liquid contains a mixture of highly purified ionizable molecules that produces strong reference peaks during calibration. Its components include caffeine, MRFA, Ultramark 1621 and n-butylamine in an acetonitrile/methanol/acetic-acid solution. The liquid can be loaded into a syringe and introduced directly into the instrument for routine calibration. It is compatible with LTQ Velos and Velos Pro, LTQ Orbitrap Velos and Orbitrap Velos Pro, Orbitrap Elite and Q Exactive mass spectrometers. The solution is prepared with mass-spectrometry-grade reagents and supplied in a non-leachable container to reduce contamination from the packaging. This format is intended for routine instrument calibration when a defined positive-ion mixture is required to verify mass-axis performance and maintain consistent MS operation.
