MS Calibration Solution, Atmospheric Pressure Ionization
Calibration compounds are used by scientists to adjust the mass calibration scales, as well as the relative intensities of ions to match with those of the known entities. This operation is carried out on all mass spectrometers because even the most subtle of changes in electronics, cleanliness of the surfaces, and a lab's ambient condition can affect the instrument's ability to reproduce a meaningful result and measurement.
For the least demanding analysis on nominal-mass instruments, the need for calibration can be infrequent and a check of its response more frequent. To ensure that lab results are of the highest accuracy, very close monitoring is required for even the minute of changes in how the equipment is performing.
Waters has a range of different MS Calibration solutions available that you can choose from depending on the conditions of your experiment. The MS Calibration Solution, Atmospheric Pressure Ionization, is a standard based on Sodium Iodide. The equipment is shipped containing 15 mL of volume of the standard within a Nalgene Bottle and has a shelf life of 18 months. Nalgene Bottles are known for being durable, leak-proof, easy to carry, high capacity, wide-mouthed, and graduated. It is recommended to keep and store the standard at room temperature and standard pressure.
The Atmospheric Pressure Ionization MS Calibration Solution contains NaCsI: Sodium Iodide 2ug/ul, +1%, -0% Cesium Iodide 50 ng/ul, +1%, -0% in 50/50 IPA/Water with a volume of 15 mL within a Nalgene Bottle.
