• intros：{"brand_intro":"月旭科技（Welch Materials）是中国本土色谱耗材领军企业，成立于2003年，总部位于上海。创始人赵岳星博士曾在美国色谱行业工作多年，回国后立志打破进口垄断。月旭以'中国智造'为核心理念，拥有多项硅胶键合专利，其Xtimate系列色谱柱在生物制药领域逐渐崭露头角。品控上采用全自动生产线和100%出厂测试，价格仅为进口品牌的50%-60%。在中国市场，月旭是'国产替代'浪潮中的代表品牌，深受预算有限的实验室欢迎。","product_intro":"Xtimate Bio-300 C18是月旭针对生物大分子开发的宽孔径柱，孔径300Å，采用高纯硅胶（金属杂质<8ppm）和双封端技术。核心卖点：价格仅为进口一半、柱效媲美岛津、支持定制规格。适用于生物仿制药分析、疫苗纯化等。相比安捷伦，月旭在价格上优势明显，但品牌知名度和批次稳定性仍有差距。用户评价'国产之光，性价比无敌'。","key_specs":{"孔径":"300Å（大分子兼容）","粒径":"5μm（经典粒径）","pH范围":"2-8（标准范围）","最高耐压":"400 bar（适配常规HPLC）","碳载量":"11%（中等疏水性）","柱长规格":"150mm（通用规格）"}}
