Problems solved by technology

Therefore, secondary pollution may occur during actual use
[0004] In the Chinese Pharmacopoeia, the content determination of potassium chloride in the compound sodium chloride injection adopts the sodium tetraphenylborate method. This method is complicated and time-consuming. The sudden jump phenomenon is not obvious and causes errors

Abstract

The invention relates to a method for measuring the content of potassium chloride and sodium chloride in a potassium chloride and sodium chloride injection solution, and a method for determining whether the content of potassium chloride and sodium chloride in the potassium chloride and sodium chloride injection solution meets quality standards. The measuring method is carried out through an atomic absorption spectrometry method by an atomic absorption spectrophotometer.

Description

technical field [0001] The invention relates to a method for determining the content of potassium chloride and sodium chloride in potassium chloride and sodium chloride injection, and a method for determining whether the content of potassium chloride and sodium chloride in potassium chloride and sodium chloride injection meets the quality standard method. Background technique [0002] Potassium chloride (KCl) is one of the most basic clinical medicines. It is a product in the national basic medical drug catalog and a national social insurance catalogue. It is mainly used to treat various hypokalemia and has been widely used in various hospitals for a long time. According to the Merck Manual, Seventeenth Edition, p. 157: For KCl supplementation, glucose solution is not an ideal choice, because the subsequent increase in the patient's plasma insulin level can lead to aggravation of transient hypokalemia and exacerbation of symptoms, especially digitalis patient. Finally, whe...
