Waters Corp Waters MS Calibration Solution, Atmospheric Pressure Ionization, 15 mL, 18 Months Shelf Life
This standard is used for Mass Spec calibration assessment, adjusting mass calibration scales and relative ion intensities to known entities. Essential for all mass spectrometers, it addresses how subtle changes in electronics, surface cleanliness, and lab conditions affect instrument performance. While calibration is infrequent for nominal-mass instruments, response checks are vital, with close monitoring required for high accuracy.
