1引言啤酒花深加工产品异α-酸与四氢异α-酸近年来已被全国各大啤酒厂广泛使用，但并无统一检测手段。文献报道的方法用乙腈和水作为流动相，单独测定四氢异α-酸。乙腈价格较高，用此方法进行产品质量控制成本高，本法采用甲醇代替乙腈，大大降低成本。分离效果好，并可同时?
1 Introduction Hypereutectic acid and tetrahydroiso iso-α-hydroxy acid have been widely used by major breweries throughout the country in recent years, but there is no uniform test method. The method reported in the literature uses acetonitrile and water as the mobile phase, and tetrahydroiso iso-α-acid is measured separately. Acetonitrile higher prices, using this method of product quality control costs are high, the law of methanol instead of acetonitrile, greatly reducing costs. Separation effect is good, and at the same time?
