• intros：{"brand_intro":"阿拉丁（Aladdin）是上海阿拉丁生化科技股份有限公司旗下品牌，成立于2009年，专注于科研试剂与耗材的电商化销售。品牌以\"让科研更便捷\"为理念，通过自建电商平台和京东/天猫旗舰店，提供超过10万种产品。阿拉丁的品控采用\"小批量、多批次\"策略，每批次均附COA（分析证书）。虽然品牌历史较短，但凭借快速的物流（全国48小时达）和亲民的价格，迅速在高校和初创企业中获得口碑。其硝酸盐检测试纸是入门级市场的爆款产品。","product_intro":"阿拉丁硝酸盐检测试纸采用改良的格里斯法，将显色剂固定在纸基上，只需将试纸浸入水样1秒，10秒后即可通过比色卡读取结果。检测范围0-50 mg/L NO3-N，精度约±10 mg/L。核心卖点：极速检测（10秒出结果）、无需任何仪器、便携（可装进口袋）。适用于家庭饮用水自检、户外水质快速评估、农业灌溉水粗筛等场景。相比哈希和默克的产品，阿拉丁试纸精度低得多，但胜在零门槛和极低成本（单次不到0.5元）。","key_specs":{"检测范围":"0-50 mg/L NO3-N（半定量）","检测方法":"格里斯法（纸基显色）","反应时间":"10秒","精度":"±10 mg/L","保质期":"12个月（室温避光）","包装规格":"100条/盒"}}
