Optimization of Isothiocyanates in Human Urine by High Performance Liquid Chromatography;

Attractive activity of some human urine chemicals toward the yellow-spined bamboo locust,Ceracris kiangsu

Tap water and human urine samples were determined by this method,and satisfying data were gained.

Determination of Tyrosine in Urine Spectrophotometric Method;

For chemical pre-extraction, MSTFA/TMSL derivatization reaction, GC/MS analysis, it is confirmed that two main metabolites (19-no-randrosterone and 19-noretiocholanolone) were found in nandrolone urine.

Based on the behavior of Ceracris kiangsu attracted by salt taste and urine,experiments indicated that with the trap of urine mixed with DDVP(1∶100),489 C.

The results show that the sanitation has a good degradation efficiency for treating human excrements,and it could reach the target of non-water,"zero pollution,zero infection, zero emission" and "quantitative reduction,innocuity,resource utilization".

It can be used to determine the concentration of chloride ions in the diluted urines and the artificial urine.

It was successfully applied to the determination of beverage、tap water and artificial urine and satisfying results were attained.

Purified monoclonal antibodies against human urokinase by Protein A-Sepharose CL 48 are coupled to CNBr-Sepharose 4B.

HPLC determination of oxalate in human urine;

Based on this complex had characteristic fluorescence of europium (Ⅲ), a europium-sensitized fluorescence method was established for determination of pefloxacin mesylate capsules and its concentration in human urine.

A high performance liquid chromatography-electrospray ionization mass spectrometry(LC-ESI/MS) was developed to screen and determine trenbolone,tetrahydrogestrinone and gestrinone in human urine.
