• intros：{"brand_intro":"月旭科技（Welch Materials）成立于2003年，是中国本土色谱耗材领军企业。创始人方晓东博士曾任职于安捷伦，回国后创立月旭，致力于打破进口垄断。其品控理念强调\"对标国际标准\"，从硅胶合成到键合工艺均自主研发。月旭在中国市场以\"国产替代\"著称，尤其受高校和中小药企欢迎。","product_intro":"Welchrom C18是月旭的经典通用柱，定位国产高性价比。核心卖点：高纯度硅胶、双封端技术、价格仅为进口柱的1/2。适用于教学实验、常规质控、方法开发。相比安捷伦ZORBAX，其价格低60%以上；相比岛津GIST，其柱效接近但寿命略短。","key_specs":{"固定相":"C18（高纯硅胶）","粒径":"5 μm，标准HPLC","柱长":"150 mm，通用长度","内径":"4.6 mm，常规内径","pH范围":"2-8，标准范围","最高耐压":"400 bar，常规HPLC"}}
