Features

  • GA-3系列包括三气体分析(O₂、CO₂和H₂O),可通过单通道、双通道或四通道配置
  • SableHD™技术确保达到0.0001%分辨率
  • 水汽补偿消除样品气体干燥,提高数据准确性

DESCRIPTION

Promethion GA-3代气体分析仪包括水汽、CO₂和O₂分析。每个分析仪通路都包含在一款Sable专门设计的独立单刀片中,放置在定制的电子外壳内。这不仅简化了系统配置,还缩短了分析仪之间的管道长度,以最小化复杂化数据分析的滞后效应。这些分析仪的核心是SableHD™高清晰度技术,实现了0.0001%的分辨率。GA-3从FR-8流量发生器选择的流量中采样空气。空气流经一个多路管道,流量控制器从中抽取主流量的一部分,通常为250-400 mL/分钟(可由用户设置)。

该部分样品然后通过水汽分析仪、CO₂分析仪和O₂分析仪进行测试。设备内部温度恒定在37°C,为分析仪提供稳定的环境,并防止冷凝。GA-3还包含一个准确、高分辨率的气压分析仪。通过其Sable Bus接口的命令,GA-3可以将化学洗涤剂柱切换到气流中。该洗涤剂柱会将通过它的气流中的水汽去除,并使用O2稀释技术校准水汽分析仪。*可选地,它还可以去除CO₂并将CO₂分析仪校零。这是样品气流干燥的唯一时刻。其他时间,使用水汽和气压分析仪的数据,在数学上对O₂和CO₂的水汽稀释进行补偿。Promethion GA-3气体分析仪是唯一具备此功能的系统。
