ICUMSA Method GS7-24 (2011)
Material: Molasses, Technical Sugar Syrups, Cane Juice
Analytes: Glucose, Fructose, Sucrose
Method Technique: Chromatography
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.
