Determination of 5-hydroxymethylfurfural in exported wine
Liquid chromatography
1 Scope
This part of SN/T 4675 specifies the method for the determination of 5-hydroxymethylfurfural in wine by high performance liquid chromatography.
This section applies to the qualitative detection and quantitative detection of 5-hydroxymethyl furfural in wine.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 6682 analytical laboratory water specifications and test methods
3 method principle
After 5-hydroxymethylfurfural in wine was separated by reversed-phase liquid chromatography, it was detected by UV detector at 284nm,
Time for qualitative, standard curve of external standard method.
4 Reagents and materials
Reagents were of analytical grade unless otherwise stated. Water using GB/T 6682 provisions of a water.
4.1 Methanol (CH3OH). Chromatographic purity.
4.2 10% methanol in water (volume fraction). Accurately draw 100mL of methanol (4.1), water to volume 1L, mix.
4.3 Standard Substance 5-hydroxymethylfurfural (C6H6O3, CAS No. 67-47-0), purity
≥98%.
4.4 Standard stock solution Accurately weigh the appropriate amount of 5-hydroxymethyl furfural standard substance, with 10% aqueous methanol solution (4.2) formulated at a concentration of
200mg/L standard stock solution. The solution can be stored in a sealed brown bottle at 0 ° C to 4 ° C for 2 to 3 months.
4.5 standard intermediate solution. Accurately measure the standard stock solution (4.4) 10.0mL in 100mL volumetric flask with 10% aqueous methanol
(4.2) constant volume to the mark, dubbed the concentration of 20.0mg/L standard intermediate solution. The solution is in a sealed brown bottle at 0 ° C to 4 ° C
Can save 2 to 3 months.
4.6 standard working solution, respectively, accurately measure the standard intermediate solution (4.5) 0.05mL, 0.1mL, 0.25mL, 0.5mL, 1.0mL,
2.5mL in 10mL volumetric flask, dilute to volume with 10% aqueous methanol solution (4.2), respectively, dubbed 0.1mg/L, 0.2mg/L,
0.5mg/L, 1.0mg/L, 2.0mg/L, 5.0mg/L standard working solution, now with the current use.
4.7 Microporous membrane .0.45μm, water system.
5 instruments and equipment
5.1 High Performance Liquid Chromatograph with UV Detector.
