Application of NMR and MS to Structural Analysis of Saccharide;

The initiation systems,relative molecular mass,etc of two foreign polymeric flocculants were analyzed by IR,NMR,X-ray energy spectrum etc.

Two novel chiral macrocyclic dioxopolyamines,which can be used as NMR chiral solvating agents(CSAs) for chiral carboxylic acids,were synthesized from L-proline through esterification,bridging and ring-closing reaction.

We applied nuclear magnetic resonance spectroscopy(NMR)to study pancreatic juice(PJ) taken from patients with chronic pancreatitis(CP) and pancreatic cancer.

Thin layer chromatography (TLC) was applied to separate phenyldibenzophosphole (PDBP) sulfonated products, and the structure of PDBP oxides in PDBP sulfonated products was determined by electrospray ionization mass spectrometry (ESI MS), 13 C nuclear magnetic resonance (NMR), 1H NMR and infrared spectroscopy (IR).

The phase of aluminum citrate in an aqueous solution was investigated by using ()~(27)Al nuclear magnetic resonance, spin-lattice relaxation time, digital matching, atomic absorption spectrography and dialysis methods.
