Studies on bile acids: The microquantitative separation of cellular bile acids by gas-liquid chromatography. [PDF]
1. A method is described for the quantitative isolation of bile acids from cellular material. Homogenates of rat liver are freeze-dried and extracted exhaustively with 95% (v/v) ethanol containing 0.1% (v/v) of aq. ammonia (sp.gr.

Bis(trimethylsilyl)acetamide in the silylation of lipolysis products for gas-liquid chromatography
When bis(trimethylsilyl)acetamide is used to silylate lipolysates for gas-liquid chromatography, the pyridine solution containing the sample and silylating agent can be injected directly onto the column.

Singular Shocks in a Chromatography Model [PDF]
We consider a system of two equations that can be used to describe nonlinear chromatography and produce a coherent explanation and description of the unbounded solutions (singular shocks) that appear in M. Mazzotti's model. We use the methods of Geometric Singular Perturbation Theory, to show existence of a viscous solution to Dafermos-DiPerna ...

Detection of Urethane in Non-alcoholic Fermented Food [PDF]
Among fermented foods, urethane often appears, which is a “2A” grade carcinogen. There are many types of fermented foods in my country, and the detection methods are not uniform enough, and no specific urethane detection standards have been formed.
