上海辉世GC-460气相色谱仪在执行GBT 25223-2024《动植物油脂 甾醇组成和甾醇总量的
测定 气相色谱法》标准中表现出良好适配性。通过配置高灵敏度检测系统与优化的柱温程序，
可实现对多种甾醇类物质的有效分离与准确定量。该方法适用于经皂化、水解及衍生处
理的动植物油脂样品，能对β-谷甾醇、豆甾醇等主要成分进行可靠分析。GC-460操作简便、
信号稳定，在油脂质量控制、掺假监测与营养评价等应用场景中具有良好的方法学基础支持。
The Shanghai Huishi GC-460 Gas Chromatograph demonstrates excellent compatibility
when implementing the GBT 25223-2024standard "Animal and Vegetable Fats and Oils -
\Determination of Sterol Composition and Total Sterol Content by Gas Chromatography
." Equipped with a high-sensitivity detection system and optimized column temperature
programming, it achieves effective separationand accurate quantification of various sterol
compounds. This method is suitable for analyzing saponified, hydrolyzed, and derivatized
animal and vegetable oil samples, enabling reliable analysis of major components such as
β-sitosterol and stigmasterol. The GC-460features simple operation and stable signal output
, providing solid methodological support for application scenarios including oil quality
control, adulteration monitoring, and nutritional evaluation.
