Chen, Yong-kang published the artcileStudy of methodology validation of detection sodium content in esomeprazole sodium, Related Products of imidazoles-derivatives, the publication is Huaxue Gongchengshi (2016), 30(4), 67-70, database is CAplus.
In this paper, the at. absorption spectrometry (AAS) method for the determination of sodium in esomeprazole sodium was established. Using the standard curve method, the detection wavelength was 589.0 nm. Exptl. results show that at 589.0 nm the blank solution has no interference with the determination of sodium, linear study shows that the concentration of sodium within 0.5∼4.0 mg·L-1 range, the absorbance A has a good linear relationship with the concentration of C, and R2 is greater than 0.999. By method validation: accuracy, solution stability, repeatability and accuracy are good, at the same time this method has good durability and can be used as the determination method of sodium content in esomeprazole sodium.
