GB/T 18932.22-2003 stipulates the determination of fructose, glucose, sucrose and maltose in honey by liquid chromatograph differential refractive spectrometry. The standard clarifies the principle, separates saccharide by means of liquid chromatograph, and detects by differential refractive light. Put forward performance requirements for Liquid Chromatography (LC), differential refractive light Detector and other equipment. Specify the collection, processing and preparation of honey samples in detail. Describe the detection process, including chromatograph condition setting, sample injection and data processing. With this standard, the content of these saccharide in honey can be accurately determined, providing a powerful means for mass detection, authenticity identification and quality grading of honey.
