产品详情
简单介绍：
日本光明理化学工业株式会社中国代理商，汽油检测管110S GASOLINE，活性炭采集管251S/251S2，吸收管是用来吸附捕集有机溶剂的，通常活性炭管用于低极性的物质，使用时，切断管子，接上隔膜泵吸入气样。然后，用溶剂萃取（如二硫化碳），再用色谱法进行分析，100-500ml/min，100mg，100-500ml/min，150mg。

日本光明理化学工业株式会社中国代理商
日本光明理化学工业株式会社在气体分析领域开拓了六十年，形成了驰名于世的“北川”式气体快速分析法，“北川”的历史就是检测管的历史。
检测管的特长：无论何时：由于不用分析仪器和化学药剂，省略了测量前的准备工作，无论何时都可以进行测定
- 无论何地：极为小巧便于携带，只要有微量的空气就可以进行测定，*适合于现场测定
- 无论何人：测定的操作非常简单，无论专业人士或非专业人士
- 多种气体：可以检测多达400余种气体
- 快速：测定的结果几分钟就可得到，可以立即转入下一步操作
- **：不用电源、热源，即使有易燃易爆的气体存在也可以确保操作**
检测管的用途：作业环境的测定：日本劳动省颁布的《作业环境操作标准》中采用了本公司的13种测试管，用途以现场作业为主，另外在建筑、事务所等环境保护工作中也有着广泛的应用
- 防火、防爆：可以在现场快速的测定可燃性气体的浓度，广泛用于检测易燃易爆气体的泄漏、生产，以防止火灾、爆炸事故的发生
- 工程管理：在各种工业生产中，将气体作为工业原料或中间产品使用时，用于测定气体的不纯物，以提高产品质量，防止催化剂的污染提高生产效率
- 污染源的检测：在现场可以迅速测定烟道中的有害气体，如亚硫酸气、氮的氧化物等，适用于大气污染的污染源管理
- 燃烧效率的检查：适合测定燃烧排气中的一氧化碳、二氧化碳、氧气等，以检查燃烧设备的效率
