Four precise, accurate, selective, and sensitive UV-spectrophotometric methods were developed and validated for the simultaneous determination of a binary mixture of Oxytetracycline HCl (OXY) and Flunixin Meglumine (FLU). The first method, dual wavelength (DW), depends on measuring the difference in absorbance (ΔA 273.4-327 nm) for the determination of OXY where FLU is zero while FLU is determi...

Micrococcus luteus was employed for the assay of rifampicin in fixed-dose combinations (FDCs) of anti-tubercular drugs containing rifampicin, isoniazid, pyrazinamide and ethambutal. The microbiological assay was compared with spectrophotometric assay for estimation of rifampicin in the FDCs as well as in dissolution studies of the FDCs. The microbiological method was found to be more sensitive ...

Metronidazole in METRONIDAZOLE I.V. Infusion 500mg/100ml was determined by Spectrophotometric method. Being a very simple, reliable and sensitive method was developed and adopted to perform the analysis of METRONIDAZOLE I.V. Infusion 500mg/100ml. The Spectrophotometric method described was found to be simple, sensitive and accurate. Therefore this could be applied for the determination of METRO...

A highly selective methacrylic based molecularly imprinted polymer (MIP) was synthesized and applied for the separation and the pre-concentration of salbutamol in urine samples. Spectrophotometric determination of salbutamol was achieved using 2,6-dichloroquinone chlorimide as colorimetric reagent. The detection limit of the method was ca. 13 ng mL in urine after pre-concentration of the sample...

Simple and accurate spectrophotometric and HPLC method was developed for determination of Fexofenadine in tablets dosage form. The spectrophotometric method was developed by dissolving tablets in 1:1 Methanol to make solution of 10ppm giving absorbance at 220nm. The experimental conditions were optimized and Beers law was obeyed over the applicable concentration range. The application of HPLC p...

Several methods for determining urea in blood and urine are in use in clinical laboratories, but none is ideal in mass routine analysis. The spectrophotometric method based on a modified Ehrlich reagent proposed by Watt and Chrisp (1954) for pure solutions is therefore of interest because it can be modified for use in mass clinical analyses of blood and urine. Brown (1959) has modified the meth...

A method comparison study for estimation of serum Calcium and Phosphorus levels and their alterations in CKD (Chronic Kidney Disease) patients was done. Serum Calcium was estimated by O-cresolphthalein complexone spectrophotometric method and NM BAPTA autoanalyzer method. Serum Phosphorus was estimated by the Gomorri’s spectrophotometric method and Phosphomolybdate UV autoanalyzer method. The n...
