ABSTRACT

Objective:

To establish an analytical method for measuring the concentration of glucose in saliva by ion chromatography.

Methods:

The proteins in saliva were removed by thermal denaturation method, CarboPac PA20 (3×30 mm) was used as a protective column and CarboPac PA20 (3×150 mm) was used as an analytical column for ion chromatography analysis. Gradient elution was carried out with A ultra-pure water, B 250 mmol/L NaOH solution and C 500 mmol/L NaAc solution. Pulsed ampere detector was used for detection.

Results:

This method had a good linear relationship in the range of 0.04 to 0.12 mg/L, with a linear relation coefficient of 0.9967. The detection limit of glucose was 2 μg/L, the mean value of the relative standard deviation (RSD) of the repeatability measurement was 0.75%, and the average spike recovery was 103.07%.

Conclusion:

This method is simple, sensitive, accurate and stable, and can be used for the determination of glucose concentration in saliva.
