Determination of Myo-Inositol in Infant, Pediatric, and Adult Formulas by Ion Chromatography-Pulsed Amperometric Detection and Column Switching: Collaborative Study, Final Action 2011.18

Abstract A collaborative study of an ion chromatographic tech’ nique of high-performance anion-exchange with pulsed amperometric detection has been completed. The procedure was used to determine sucrose, glucose, and fructose in 8 cane molasses samples and sucrose in 5 beet molasses samples. Eleven laboratories took part in the study. Repeatability and reproducibility values for sucrose, glucose, and fructose were excellent for both types of samples. All criteria for accepting the method for sugars in both beet and cane molasses were met. The ion chromatographic method for determination of sugars in beet and cane final molasses has been adopted first action by AOAC INTERNATIONAL.

Relative Standard

A practical method for the determination of cyanide in bamboo shoots has been developed using microdiffusion preparation integrated with ion chromatography–pulsed amperometric detection (IC-PAD). Cyanide was released from bamboo shoots after Conway cell microdiffusion, and then analysed by IC-PAD. In comparison with the previously reported methods, derivatization and ion-pairing agent addition were not required in this proposed microdiffusion combined with IC-PAD method. The microdiffusion parameters were optimized including hydrolysis systems, temperature, time, and so on. Under the optimum conditions, the linear range of the calibration curve for cyanide was 0.2–200.0 µg kg −1 with satisfactory correlation coefficients of 0.9996 and the limit of detection was 0.2 µg kg −1 ( S/N = 3). The spiked recovery range was from 92.8 to 98.6%. The intra-day and inter-day relative standard deviations of cyanide were 2.7–14.9% and 3.0–18.3%, respectively. This method was proved to be convenient in operation with high sensitivity, precision and accuracy, and was successfully applied in the determination of cyanide in bamboo shoot samples.

Optimized Conditions

A simple and accurate ion chromatography (IC) method with pulsed amperometric detection (PAD) was proposed for the determination of cyanide ion in urine, sweat, and saliva samples. The sample pretreatment relies on alkaline digestion and application of Dionex OnGuard II H cartridge. Under the optimized conditions, the method showed good linearity in the range of 1–100 μg/L for urine, 5–100 μg/L for saliva, and 3–100 μg/L for sweat samples with determination coefficients (R)>0.992. Low detection limits (LODs) in the range of 1.8 μg/L, 5.1 μg/L, and 5.8 μg/L for urine, saliva, and sweat samples, respectively, and good repeatability (CV < 3%, n=3) were obtained. The proposed method has been successfully applied to the analysis of human biological samples.
