Acidic–basic gas chromatography

Journal of Microcolumn Separations, 1999
A new variant of gas chromatography: acidic–basic gas chromatography (ABGC) has been proposed. In ABGC gases or vapors used as a mobile phase influenced the apparent degree of dissociation of the analyte compounds in the stationary liquid phase. The method is desirable for the selective separation of acidic or basic volatile compounds. The retention of

Gas phase acidity of water clusters

Physical Chemistry Chemical Physics, 2022
In the present work, we have estimated the gas-phase acidity of different water clusters, i.e., (H2O)n, n = 1–20, 30, 35, 42, 54, 80, and 100.

Acidizing Gas Storage Wells

SPE Eastern Regional Meeting, 1997
Abstract Acidizing has typically been one of the most popular techniques used for the removal of damage in gas storage wells. Acidizing is often useful for carbonates, but surveys have indicated that as many as 30% of the sandstone wells were adversely affected by the use of acids.

Gas chromatographic analysis of dialkylbarbituric acids

Journal of Chromatography A, 1976
A variety of procedures for the derivatization of barbituric acids for gas-liquid chromatography (GLC) are described and a convenient procedure for n-alkylation of barbiturates is reported. The gas chromatographic behavior of derivatives(methyl, ethyl, propyl, butyl, pentyl and hexyl) is discussed on the basis of the retention index.

Gas Chromatographic Determination of Hydrazoic Acid

Journal of Chromatographic Science, 1976
A gas chromatographic procedure was developed for the determination of hydrazoic acid. Two possible columns were evaluated. The limits of detectability were 1.5 ng, or approximately 0.05%, in aqueous solution (w/v) and 2 mg per liter in air.

Gas chromatography of urinary aromatic acids

Analytical Biochemistry, 1962
Abstract A method is described for the separation and identification of 29 aromatic acids by gas chromatography. Aromatic acids without phenolic groups are converted to their methyl esters by reaction with ethereal diazomethane and chromatographed on an 8% ethylene glycol adipate column at 170°C.

Gas Chromatography of Amino Acid Derivatives

1970
Extensive studies have been made in attempts to adapt the gas-liquid chromatography technique to amino acids analysis. Since the discovery of the gas-liquid chromatograph, the idea of using it for amino acids analysis has been enthusiastically expounded because of its great potential in providing a means by which qualitative and quantitative analysis ...
