Method Abstract

The High Performance Ion Chromatographic (HPIC) method is used for the determination of sucrose, glucose and fructose in cane juices, syrups and molasses and sucrose in beet molasses.

If a choice is available to the user for the Determination of Glucose, Fructose and Sucrose in Cane Juices, Syrups and Molasses then ICUMSA recommends that Method G7/4/3-22 (GC) is used preferentially.

For (30 to 35) g/100g sucrose in cane molasses, the absolute difference between two results obtained under repeatability conditions should not be greater than 0.73 g/100g.

The absolute difference between two results on such samples obtained under reproducibility conditions should not be greater than 1.24 g/100 g.

For (50 to 55) g/100 g sucrose in beet molasses, the absolute difference between two results obtained under repeatability conditions should not be greater than 0.82 g/100 g.

The absolute difference between two results on such samples obtained under reproducibility conditions should not be greater than 2.40 g/100 g.

For (1 to 6) g/100 g glucose in cane molasses, the absolute difference between two results obtained under repeatability conditions should not be greater than 0.17 g/100 g.

The absolute difference between two results on such samples obtained under reproducibility conditions should not be greater than 0.37 g/100 g.

For (5 to 10) g/100 g fructose in cane molasses, the absolute difference between two results obtained under repeatability conditions should not be greater than 0.23 g/100 g.

The absolute difference between two results on such samples obtained under reproducibility conditions should not be greater than 0.38 g/100 g.
