Computer treatment of gas-liquid chromatographic data, with special reference to fatty acid methyl esters.
A computer program is described which analyzes output punched directly onto paper tape from a gas-liquid chromatograph. Although this program was written specifically for samples of fatty acid methyl esters derived from adipose tissue triglycerides which are eluted within 1 hr, modification of the dimension statements in the program would enable it to deal with samples which require a longer ti...

متن کاملGas-chromatographic detection of phthalic acid esters.
Each second, the rivers of the world add 109 kg of fresh water to the oceans, and with this water comes tremendous quantities of salts, clay minerals, and other suspended solids. Although the Amazon River makes the largest contribution of fresh water to the sea, its waters are relatively uncontaminated. On the other hand, the Mississippi River, the third largest river, which delivers only about...
متن کاملGas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...
