Matrix Assisted Laser Desorption Ionization Mass Spectrometry (MALDI MS) has been an invaluable technique to increase the mass limit of samples being analyzed.  On our rebuilt MALDI RTOF-MS, calibration experiments were performed in the750-3500 Da mass range using the following samples: Bradykinin fragment 1-7, Angiotensin II, P14R, ACTH fragment 18-39, and Insulin B chain (Sigma Aldrich).  The experimentally obtained mass spectra of all analytes were compared to literature spectra to ensure the spectrometer produced accurate and reproducible data.  The results of the calibration experiments will be presented.
