Improved methodology for amino acid analysis coupled with semi-micro isolation techniques
make feasible the measurement of individual amino acids from marine waters where sample …

A conventional amino acid analyzer was modified to allow detection of dissolved free amino
acids in a direct injection of 0.5 to 2.0 ml of seawater. The amino acids were monitored …

A new gas-chromatographic method was used to determine amino acids. It gave complete
separation of small samples quickly and quantitatively. A one-step reaction …

A novel reaction buffer for the derivatization of amino acids in seawater with the o-
phthaldialdehyde/2-mercaptoethanol reagent is introduced. This buffer involves citric …

In the past, the determination of dissolved free amino acids in seawater has proven to be
analytically challenging mainly because these compounds are present in low concentrations …

Achieving low and consistent levels of contamination in sampling and analysis is crucial
because of the low concentrations of amino acids and carbohydrates in marine samples. In …

A method is described for the detection of free α-amino acids in the picomole range in
seawater samples of less than 100 ml volume. The modifications made to a standard amino …

We examined a vapor-phase hydrolysis method for estimating dissolved combined amino
acid (DCAA) concentrations in seawater. The DCAA concentrations determined by this …

Dissolved free amino acids (DFAAs) are a significant source of carbon and nitrogen for
marine bacteria. The various organisms present in coastal surface seawater contain …

A detailed method for the analysis of dissolved free amino acids (DFAA) and ammonium by
reverse phase high performance chromatography of fluorescent derivatives using …
