Abstract

The invention belongs to the field of medical technologies and relates to a detecting method for 5-hydroxymethylfurfural in a peritoneal dialysis solution. A 5-hydroxymethylfurfural comparison product is precisely weighed and dissolved with water, a comparison product solution is prepared, an appropriate quantity of peritoneal dialysis solution is taken to be put into a measuring bottle and diluted with water to a scale, a solution for a testing product is prepared, 20 microliters of comparison fluid and 20 microliters of fluid for testing are precisely taken and injected into a chromatographic instrument, a chromatogram map is recorded, and the labeled amount of 5-hydroxymethylfurfural in the peritoneal dialysis solution is obtained according to an external standard method through peak area calculation; through efficient liquid chromatography, the content of 5-hydroxymethylfurfural in the peritoneal dialysis solution is accurately detected, accurate control over the quality of the peritoneal dialysis solution is achieved, the technology is easily optimized, and product quality and safety are improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to a method for detecting 5-hydroxymethylfurfural in peritoneal dialysis fluid. Background technique [0002] Peritoneal dialysis solution is a clear, sterile, pyrogen-free and endotoxin-free solution with a suitable pH value prepared by sodium, potassium, calcium, magnesium, chlorine, buffer substances and glucose. Clinically, it can be used to treat acute or chronic renal failure, drug poisoning, refractory heart failure, severe electrolyte disturbance, such as hyperkalemia, etc. The amount of glucose degradation product 5-hydroxymethylfurfural in the finished product is one of the reasons to investigate the stability of the dialysate. 5-Hydroxymethylfurfural is an aldehyde compound produced by the dehydration of monosaccharide compounds such as glucose under high temperature or weak acid conditions. This compound is harmful to human striated muscles and internal organs. 5-Hydr...
