• intros：{"brand_intro":"月旭科技（Welch Materials）成立于2003年中国上海，是国内色谱耗材领域的领军企业。创始人赵岳星博士曾任职于美国色谱公司，回国后致力于色谱柱国产化。月旭的核心技术在于\"超纯硅胶合成\"与\"表面修饰工艺\"，其Welchrom系列性能接近进口品牌。品控上，月旭通过ISO 9001认证，每根柱子出厂前均进行HPLC测试。月旭以\"进口品质、国产价格\"为理念，在中国市场快速崛起。","product_intro":"Welchrom C18 是月旭科技面向通用分析推出的高性价比反相层析柱，定位入门至中级市场。核心卖点：碳载量16%提供良好分离度；pH范围2-8，适配常规HPLC；价格仅为进口品牌的1/3。适用于教学实验、中小企业质控及方法预试。与竞品相比，柱效与寿命接近岛津Shim-pack，但价格更低。是国产替代的热门选择，用户评价\"性价比之王\"。","key_specs":{"填料类型":"C18（超纯硅胶）","粒径":"5 µm","柱尺寸":"250 mm × 4.6 mm（内径）","pH范围":"2-8","最大压力":"350 bar","适用场景":"教学实验、常规质控、方法预试"}}
