According to the United States Pharmacopeia and the National Formulary Pharmacopeial Forum (PF 45(5)*), sucrose assay and analysis of impurities (related substances) should be carried out with a HPLC method and a column filled with L19 packing material, and meets following requirements.
The use of a sugar analysis column, EP SC1011-7F, confirmed the requirements were met.

System suitability requirements:
   Peak valley ratio of raffinose and sucrose: ≥ 2.5
   Resolution of sucrose and dextrose: ≥ 1.5
   Relative standard deviation (RSD) of sucrose peak area: ≤ 0.73%
