Short Description: MALDI TOF/TOF Mass Spectrometer for automated MS and MS/MS identification of polymers and proteins Reflectron resolution broadband mode ≥ 13,000 for Somatostatin (m/z 3,147) FWHM Reflectron sensitivity 500 amol [Glu1]-Fibrinopeptide B (m/z 1,570.7) at S/N > 20:1 Reflectron mass accuracy≤ 20 ppm with external calibration		Picture of the Equipment
Available Experiments/Techniques: Mass spectrometry measurements of polymers in -linear-mode, high resolution reflectron mode and TOF/TOF (LIFT) mode.
Special Equipment: Polymerix Software Module for Analysis of Homo- and Copolymers
Measurements on the equipment are currently done by:		Trained scientific service personal
Recent Publications, where this instrument was important (citation):		Macromolecular Rapid Communications (2009), Volume 30, Issue 15, Pages 1323-1327
Typical problems that may be solved with this instrument:		-determination of molar masses and molar mass distributions of polymers in a molar mass range between 100 and 100000 daltons -analysis of end groups, composition of copolymers, structure of repeating units after polymeranalogous reactions, side reactions
