flight profile
2.Methods Sera of 16 healthy volunteers,27 type 2 diabetic patients without DR and 21 type 2 diabetic retinopathy patients were analyzed by using surface enhanced laser desorption/ionization time-of-flight mass spectrometry(SELDI-TOF-MS) and Biomarker Wizard Software to identify potential differences in protein or polypeptide profile.
3.A CCD big screen image displaying system with the resolution of 1 micron and the observing field of 160 μm×160 μm is developed successfully on a sputter initiated resonance ionization time of flight mass spectrometer. The size and distribution of gold grains in pyrite samples are analyzed by means of this system and the depth profile of gold is also studied.
