RP-UPLC method development and validation for the simultaneous estimation of ibuprofen and famotidine in pharmaceutical dosage form.

Aim And Background: A stability-indicating LC method was developed for the simultaneous determination of Ibuprofen and Famotidine in pharmaceutical dosage forms.

Materials And Methods: The chromatographic separation was achieved on Acquity UPLC BEH C-18,50 mm × 2.1 mm and 1.

Determination of trace concentrations of elements in high purity tellurium by radio frequency glow discharge optical emission spectrometer (RF-GDOES).

A method was established for the determination of trace impurities in high purity tellurium (Te) 99.9999 (6N) by radio frequency glow discharge optical emission spectrometry (RF-GDOES). The optimized parameters are power, argon pressure, pre-integration time, analysis time and selection of wavelength.
