Mass spectrometry matrix assisted laser desorption

Mass spectrometry (matrix assisted laser desorption) of the cleavage products was done by dissolving the samples in 0.1% TFA then mixing 1 pi of sample solution with 1 pi internal standard solution (bovine insulin at 0.5 pmole/pl) and 1 pi saturated matrix solution (100 mM sinapinic acid). The mixture was loaded on the probe tip, air dried, and placed in the mass spectrometer. [Pg.194]

Mass Spectrometry. An alternative to using GPC with viscometry and li t scattering detection for the determination of low molecular wei t polymer distributions is mass spectrometry. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDITOFMS) can give fast, accurate information about the degree of polymerization (molecular weight stribution).

Mass spectrometry. Matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectroscopy has been used to determine fetd/fetc in S and MMA polymerization. Chains formed by disproportionation and chains formed by combination form two distinct distributions. [Pg.95]
