FLAME PHOTOMETRY AS TOOL FOR PHARMACEUTICAL QUALITY ASSURANCE
Nishat Chowdhury*, Shingo Ueno and Md. Saiful Hoque
ABSTRACT
The need for a rapid, accurate method to determine quantitatively Na and K present together in biological fluids
has been met by the procedures to be described. Commercial intra and extra cellular fluid supplements were
obtained and assayed for quality measurements. Calibration graphs in the range of 0.00–20 ppm were obtained.
The pharmaceutical preparations should have been diluted. They were too much concentrated and accurate result
was not found. Only presence or absence of an alkali metal could be found using the traditional calibration curve
established by Dhaka University Centre for Scientific Research (CARS).
