A Safer Solution to Scrub Agents from Campbell Scientific Gas Analyzers

If you have an eddy-covariance system, you understand the importance of performing routine maintenance tasks so you can continue to acquire high-quality, consistently reliable data. Some of these maintenance tasks are straightforward, such as making sure that the optics on your gas analyzer are clean and that the transducers on your sonic anemometer are clear of any debris. Unfortunately, there’s another common maintenance task that poses some safety challenges: ensuring that the air inside your gas analyzer is free of CO₂和H.₂o使用足够的擦洗剂。

过去，您可能使用含有化学品如高氯酸镁和脱氧铝等化学品的瓶子擦洗气体分析仪的内部空气^®。如果您曾经替换这些化学品，则可能面临其中一些挑战性问题：

• Concern, or even worry, about the health hazards from contact with the chemicals
• 改变化学瓶后，在内部空气擦洗内部空气的等待时间
• Short time intervals between when chemicals need to be replaced
• Shipping regulations and the proper disposal of used chemical bottles
• Damage to the gas analyzer from liquid water interacting with the chemical bottles

What is the safer solution for this maintenance task?

At Campbell Scientific, we strive to make top-of-the-line instruments that are easy to maintain and safe for both you and the environment. We are pleased to provide you with a safer scrubbing solution. You can now use our patent pending molecular sieve technology to scrub CO₂和H.₂o来自所有天然气分析仪的内部空域。新的分子筛是我们使用的旧化学瓶的替代品EC150,Irgason.， 和EC155气体分析仪。

How can you benefit from this new solution?

随着新的更安全的分子筛瓶，您可以期待几个好处。

创新技术和提高安全性

Recently, we replaced all the internal chemicals in the gas analyzers we manufacture with a 13X zeolite molecular sieve. This molecular sieve is a material with small pores that blocks the passage of large particles such as water vapor and CO₂。这种设计确保了气体分析仪内部外壳中的空气没有那些气体。通过这项专利技术，我们是NDIR（非分散中红外线）CO的唯一提供者₂和H.₂O gas analyzers that utilize scrubbing agents—without the use of restricted caustic chemicals.

Reliable scrubbing

分子筛的擦洗能力的试验显示出先前的高氯酸镁/脱氧剂的结果^®scrubber chemical bottles. The typical scrubbing time for CO₂is less than a few hours, whereas water vapor is typically removed within a day.

持久的解决方案

Under normal use, you should only have to replace the molecular sieve approximately once every two years. (If the zero-and-span readings have drifted excessively, you will need to replace the sieve sooner.) The replacement bottles are part number32897对于Irgason和EC150和部件号33384对于EC155。

Easy maintenance

It is a quick and easy process to replace the molecular sieve within your Campbell Scientific gas analyzer. The molecular sieve material for the gas analyzers comes pre-packaged in a ready-to-use bottle that can be transferred directly into your instrument. You don’t have to worry about pouring, measuring, or spilling the material. In addition, because of the discontinuation of restricted chemicals, you don’t have to worry about shipping regulations and not being able to acquire the needed chemical bottles for the task.

No risk to the gas analyzer

使用以前的化学品，用于擦洗CO₂和H.₂o如果液态水接触并与化学瓶子反应，则存在损坏分析仪外壳的风险。如果在外壳中形成的泄漏或者瓶盖未正确收紧，可能会发生这种情况。结果是 - 在最昂贵的修复中以及在处理仪器时暴露于腐蚀性化学物质的风险。随着分子筛的添加，已经消除了这些风险。
