Perez, F.F. and Fraga, F., 1987. A precise and rapid analytical procedure for alkalinity determination. Mar. Chem., 21: 169-182. A potentiometric analytical method is proposed for the determination of the alkalinity of seawater. The precision is 0.1% and each determination takes 3 min. The technique is very easy to use, even on board ship since it is carried out in open flasks. A polynomial equ...

This paper reviews the speciation and determination of mercury by various analytical techniques such as atomic absorption spectrometry, voltammetry, inductively coupled plasma techniques, spectrophotometry, spectrofluorometry, high performance liquid chromatography, and gas chromatography. Approximately 126 research papers on the speciation and determination of mercury by various analytical tec...

synthetic antibacterial agents, which are active against Gram positive and Gram negative bacteria. They are receiving a significant attention due to their broad spectrum of activity, potency, variable indications and excellent pharmacokinetic profiles. Because of their therapeutic importance, numerous analytical methods have been developed for their determinations in pharmaceutical formulations...

Rapid determination of the absorptivity for a recombinant IgG monoclonal antibody using the Beckman equipped with both Raleigh interference and UV absorbance optical systems. The analytical ultracentrifuge data for determining spectrophotometric absorptivities is compared to experimental data from quantitative amino acid analysis and an enzymatic digestion method.

Furosemide (FUR) is an anthranilic acid derivative which is a potent diuretic widely used in the treatment of congestive heart failure and edema. FUR works by blocking the absorption of salt and fluid in the kidney tubules, causing a profound increase in urine output (diuresis). Due to the considerable use of FUR, analytical determination is frequent. In this manuscript, a review of the methods...

There have been very many methods suggested from time to time for the determination of reducing sugars, and considerable difficulty has been experienced in obtaining one which is sufficiently foolqxoof to give satisfactory results in the hands of all operators. In 1936 von Stieglitz and Home 11) reviewed several methods and recommended the electro* metric determmat~on of the end point with the ...

Oseltamivir phosphate is an antiviral drug used in the treatment and prophylaxis of both influenza virus A and influenza virus B. Oseltamivir phosphate is an ethyl ester pro-drug that is rapidly and extensively metabolized by esterases in the gastrointestinal tract and liver to its active form, oseltamivir carboxylate. There are some analytical methods in the literature for the analysis of both...

polarographic method is considered as an alternative laboratory technique for analytical method in determination of dissolved oxygen and n-n03. analytical method is a time consuming technique and is subject to several interferences due to some of constituents in sewage. in this laboratory research, the polar graphic technique with, mercury drop electrodes and titrometric method were applied in ...
