With the method of the thin-layer chromatography technology, the components in secretion of the ear-side gland and skin gland of toad are compared in respect of Bufotoxin and peptide.
This work applied the new type capillary column modified by barium sulfate. It has completed the solubilty of high boiling ester in para-methyl-toluate with the method of chromatography.
To establish a method of the opposition highly effective liquid phase chromatography (RP-HPLC) to examine pamabrom content in the pamabrom raw material and acetaminophen and pamabrom tablets.
Anion in inhalable particulate matter can be completely dissolved in water by using ultrasonator and then measured by ion chromatography.Good accuracy and precision can be obtained.
Tigogenin was separated completely from the crude sapogenins by macroporous resin column chromatography,only simple solvent Ilelute was used in the column of the separate process.
A better method was presented by adopting an external standard method of high performance liquid chromatography for the determination of Anilazine pesticides residue in foods.
A method for the simultaneous determination of captan and folpet pesticide residues in apples was developed by solid-phase extraction and high performance liquid chromatography.
In this paper,two methods for analyzing air sulphation rate were studied and compared.One was ion chromatography and the other was barium sulfate spectrophotometry.
The urine xanthopterin levels were determined in 29 healthy men(normal group),11 patients and 34 patients with cancer by fluorescence combined with paper chromatography.
Quantitative determination of jasminal by gas chromatography was studied.A quick,convenient,accurate method was obtained in the analysis of jasminal by GC16A gas chromatograph.
The soybean phosphatidylethanolamine and phosphatidylinositol were prepared by combining methods of solvents extraction and silica gel column chromatography from soybean oil sediment.
METHOD Qualitative test with thin-layer chromatography was performed on Yunkeping Granule, with Spica Prunellae Vulgaris, Herba Plantaginis and urson as the control.
The controls were homeochronous inpatients with affective disorder and normal individuals.lsoprene breath levels were measured by gas chromatography combined with mass spectroscopy(GC-MS).
Intrigued by that discovery, the team put the crude sample they were working on through two rounds of chromatography, to split it into its constituents, and repeated the tests on these.
He used gas chromatography, coupled with human sniffing, to identify about three dozen aromatic compounds contributing to the whiskey's flavor profile.
The results showed that the relative deviation of this method was less than 5% when compared with that of high-performance liquid chromatography, implying high accuracy of the presented biosensor in glucose detection in plants.
Improved laboratory techniques such as chromatography and electrophoresis led to rapid advances in physiological chemistry, which—as biochemistry—began to achieve independence from its medical origins.
