Using ultra-high purity (UHP) gases simply reduces the number of variables in air-sensitive reactions. It boils down to peace of mind, and the last thing you want to do when troubleshooting an experiment is worry about a lackluster Schlenk line.

CRS ZPure^TM CO₂ traps contain sodium hydroxide (NaOH)—and lots of it. Here is how the chemistry works in CO2 scrubbing:

The removal of oxygen from a liquid gas stream is often the most crucial protection against the degradation of equipment or chemicals..

When a CRS ZPure™ gas purifier is installed in your gas line you’re assured of ultra-pure gas delivery, with low pressure drop and good protection against particulates. This is by design backed up with testing. For example...

Recently at CRS we have been working to apply our experience in manufacturing ultra-clean polymers to a variety of new applications. We find that it is possible to manufacture an ultra-low emission conductive silicone rubber tubing which retains the conductive, mechanical, and thermal properties of standard tubing – and virtually eliminates emissions.

The easiest and most obvious answer is to use a purifier with a built-in indicator: order a replacement when it starts turning color!

Whenever possible purifiers should be installed in a vertical position to prevent “channeling” of the gas stream, which can lead to premature contaminant breakthrough.

At CRS we normally examine ‘emissions and extractables’ with a couple of different GC methods. Read about our process...

This benefits our customers by saving money on cartridges and also helps save the planet by keeping heavy metal cartridges from entering our landfills.
