Simultaneous Determination of Barbiturates and Salicylates by Ultraviolet Spectrophotometry.
A rapid method based on UV spectrophotometry is described for simultaneous determination of salicylates and barbiturates in serum. While barbiturates have no absorbance above 280 m and extracted normal serum has insignificant absorbance, salicylate has a maximal absorbance peak at 296 mjh, which is proportional to concentration. The barbiturate concentration can be calculated from absorbance di...
متن کاملSimultaneous determination of moxifloxacin and cefixime by first and ratio first derivative ultraviolet spectrophotometry
UNLABELLED BACKGROUND The new combination of moxifloxacin HCl and cefixime trihydrate is approved for the treatment of lower respiratory tract infections in adults. At initial formulation development and screening stage a fast and reliable method for the dissolution and release testing of moxifloxacin and cefixime were highly desirable. The zero order overlaid UV spectra of moxifloxacin and ...
متن کاملSimultaneous Determination of Montelukast Sodium and Bambuterol Hydrochloride in Tablet Dosage Form by Ultraviolet Spectrophotometry
A simple, accurate, and precise dual wavelength spectrophotometric method was developed for simultaneous determination of Montelukast Sodium (MTKT) and Bambuterol Hydrochloride (BAM) in combined pharmaceutical dosage forms. The method based on determination of MTKT at 322.0 nm using its absorptivity value and BAM at 266.0 nm after deduction of absorbance due to MTKT. The two drugs follow Beer-L...
متن کاملSimultaneous Estimation of Metformin and Pioglitazone by Ultraviolet Spectrophotometry
This work deals with the simultaneous estimation of metformin hydrochloride and pioglitazone hydrochloride in a bilayered tablet dosage form, without prior separation by two techniques. The methods employed are derivative spectrophotometery and Q analysis. The absorption maxima at 231 nm and 269 nm were used for the estimation of metformin and pioglitazone, respectively. Both the drugs and thei...
متن کاملDetermination of DNA Concentration and Purity by Ultraviolet Spectrophotometry
Typically, the first thing one wants to know about a DNA preparation is its concentration and purity. Both can be determined by measuring the absorption of ultraviolet light. DNA absorbs UV more or less strongly depending upon the wavelength. We will be using a NanoDrop spectrophotometer, which takes measurements at wavelengths of 260 and 280 nm, and in addition determines an absorption spectru...
