General description
众所周知，当采样空气羰基使用 DNPH 涂层硅胶设备，臭氧干扰它们的分析。为了消除这种臭氧干扰，在 DNPH 装置前使用含有 1.5g 碘化钾 (KI) 的传统臭氧擦洗装置来捕获臭氧，从而引起臭氧负干扰。在高湿度环境和阴雨条件下，碘化钾小柱（或同时含有碘化钾和 DNPH 的其他多床装置）由于湿气凝结和收集在装置内部而导致样本损失。
优点：
- 一体化臭氧洗涤器
- 无额外连接
- 检测盒无泄漏
- 高纯度吸附剂，提高痕量分析的准确性
- 低背景
- 单独包装在密封袋中，以最大限度地提高样本完整性
- 适用于 NIOSH 2016、EPA TO-11A、EPA IP-6A 和 ASTM D5197
