- Abstract
A quantitative analysis method was established by ion chromatography with pulsed amperometric detection for the determination of D-mannitol in candies.D-mannitol in the sample was separated on Dionex CarboPacTM MA1 BioLCTM column (4×250 mm) by isocratic elution with 500 mmol/L NaOH solution at the flow rate of 0.45 mL/min. Within the range of 1.0~ 10 μg/mL mass concentration of D-mannitol,its peak area shows good linear relation with the correlation coefficient of 0.999 5. The limit of detection is 0.000 33%,and the limit of quantification is 0.001%.The recoveries were in the range of 77.8%~117.9% with relative standard deviations falling in the range of 1.77%~9.41% at three spiked levels of 0.001%,0.002% and 0.005%. The method features simple operation,high sensitivity and good stability,thus it is suitable for determination of D-mannitol in candies, it can provide technical support for risk assessment and batch rapid detection of D-mannitol in candies.
