| 摘要 |
<p>The invention relates to the field of molecular mass measurement by time-of-flight mass spectrometers where the ionization of analyte substances is produced by matrix-assisted laser absorption (MALDI). Methods for the correction of flight time values based on the use of external standards are provided, and in particular methods for determining, given a MALDI target, the optimal positions of mass calibration standards are described.</p> |
