• intros：{"brand_intro":"密理博（Millipore，现属默克集团）是全球实验室纯水领域的绝对霸主，成立于1954年，总部位于美国马萨诸塞州。创始人Jack Bush博士以\"让每一滴水都纯净\"为使命，率先将离子交换与反渗透技术商业化。其品控理念近乎偏执：所有耗材均在Class 1000洁净车间生产，每批次出厂前需通过18.2 MΩ·cm电阻率测试。密理博在中国高端科研市场占有率超过60%，是Nature、Cell等顶刊实验室的标配品牌。","product_intro":"Q-Gard 1是专为Milli-Q IQ 7000系列设计的预处理柱，采用专利的Jetpore混合床树脂与活性炭复合技术，能高效去除进水中的余氯、有机物（TOC<5 ppb）及颗粒物。相比国产替代品，其树脂交换容量高出30%，且自带RFID芯片可自动记录使用量。适用于HPLC、ICP-MS、细胞培养等对水质要求极高的场景。用户反馈其寿命比普通柱长2-3个月，但价格也是国产的3倍。","key_specs":{"材料":"Jetpore混合床离子交换树脂+高碘值活性炭","处理量":"4000L（进水TOC<2ppm时）","流速":"2L/min（最大）","适配机型":"Milli-Q IQ 7000/7005","出水电阻率":"≥18.2 MΩ·cm（25°C）","TOC去除率":">99%"}}
