• intros：{"brand_intro":"颇尔（Pall Corporation）成立于1946年，是过滤、分离和纯化技术的全球领导者，总部位于美国纽约。创始人David B. Pall博士发明了世界上第一张微孔滤膜，奠定了现代过滤工业基础。在实验室纯水领域，颇尔以\"高性价比的进口替代\"著称，其Cascada系列采用独特的双波长UV氧化技术，品控严格遵循ISO 9001及FDA cGMP标准。在中国，颇尔是生物制药和食品检测实验室的优选品牌。","product_intro":"PC-1预处理柱是Cascada纯水系统的核心组件，采用\"活性炭+反渗透膜+混床树脂\"三级复合结构，能有效去除余氯、胶体及溶解性离子。其最大亮点是内置的\"智能寿命指示器\"，通过电导率实时监测树脂饱和度，避免过早更换浪费。相比密理博，价格低约30%，但出水TOC略高（<10 ppb）。适合预算有限但要求稳定的高校教学实验室和第三方检测机构。","key_specs":{"材料":"椰壳活性炭+高交联度混床树脂","处理量":"3500L（进水TOC<1ppm时）","流速":"1.5L/min（最大）","适配机型":"Cascada I/III/IV","出水电阻率":"≥18.2 MΩ·cm（25°C）","TOC去除率":">95%"}}
