Apparatus for determining molecular weight of polymers |
摘要 |
The invention is directed to an apparatus and a method for direct mass analysis of molecules and macromolecules, including polymers, using charge reduced gas phase analyte ions generated from analyte electrosprays coupled to a time of flight mass spectrometer (TOF-MS). Molecules and macromolecules, including polymers, analyzed in accordance with the invention include both water soluble and water insoluble polymers having weight average molecular weights between 1 kilodaltons (kD) and 500,000 kD.
