Simultaneous titrimetric determination of bicarbonate and titratable acid of urine.
An acid-titration method for the determination of bicarljonate and titratable acid in the one sample of urine is described. The method needs only one manipulation of the sample of urine, and was devised to simplify routine laboratory methodology. The accuracy and precision of the urinary bicarbonate method during routine laboratory use is comparable to that obtained by using the Van Slyke manom...
متن کاملThe Titrimetric Determination of “lactobacillus Case1 Factor” and “folic Acid”*
Microbiological tests have aided greatly in the isolation work on “L&o!x~ciZZus casei factor,” demonstrated by Snell and Peterson in 1940 (l), and “folic acid,” the nutrient required by Streptococcus lactis R as defined by Mitchell et al. (2). It seems likely that bacterial assays will continue to play an important role in the study of these compounds, since development of chemical methods has ...
متن کاملValidation of a HPLC Method for the Determination of Benzoic Acid and Sorbic Acid in Noodles
A simple, sensitive and specific HPLC method was validated for the simultaneous determination of benzoic acid and sorbic acid in noodles. Sample preparation involved the extraction with methanol and water (60:40, v/v). The separation was achieved on a GerminiC18 modified silica column (50 mm x 4.6 mm i.d., 5 μm particle diameter). The mobile phase consisted of 0.05 M ammonium acetate (pH 4.4) a...
متن کاملTitrimetric and Spectrophotometric Determination of Tinidazole Tablets
A simple, sensitive, rapid, reproducible, economical and easily accessible method for the determination of tinidazole tablets is described. From the experiment carried out there is the need for recrystallisation of tinidazole tablet before it is analysized. Ultraviolet (UV) absorption analysis corresponds to the result obtained with non-aqueous titration. And the best solvent to be use for non-...
متن کاملPreparation and purity determination of radiolabeled taxol and evaluation of its absorption in murine melanoma
Aim and Background:Taxol is a known substrate for P-glycoprotein, which induces drug resistance to cancerous cells. Therefore radiolabeled taxol can be a suitable probe for imaging of the P-glycoprotein transport ability to determine drug resistance. The aim of this study was to provide labeled taxol and to determine the rate of uptake in the tumor to evaluate the location of the tumor and the ...
