Appendix A
Inspection method
A.1 General provisions
Unless other requirements specified, reagents and water used in this Standard all refer to analytical reagents and Grade 3 water stipulated in GB/T 6682-2008.
Unless other requirements specified, the standard solution, impurity standard solution, preparations and products used for test shall be prepared based on the provisions of GB/T 601, GB/T 602 and GB/T 603. The solution shall refer to aqueous solution if it is not indicated.
A.2 Identification test
In the test of measuring sorbitol content, the peak retention time in sample solution chromatogram shall be consistent with that in standard solution chromatogram.
A.3 Determination of sorbitol (in dry basis)
A.3.1 Method summary
Use high performance liquid chromatography. Under the selected operating conditions, take water as mobile phase, use high-pressure infusion pump to pump mobile phase into chromatographic column which is filled with Ca type strong acid cation exchange resin filler, so as to separate each component in the sample solution. Use refractive index detector to detect. Record and process chromatographic signals by data processing system.
A.3.2 Reagents and material
A.3.2.1 Water. Grade 1 water that complies with GB/T 6682-2008.
A.3.2.2 Sorbitol standard sample. purity >=98%.
A.3.3 Apparatus
High performance liquid chromatography equipped with refractive index detector
A.3.4 Reference chromatographic conditions
A.3.4.1 Mobile phrase. water (A.3.2.1)
