Protocols 101: Picking Your Gases

How to pick your EPA protocol gas—simply and successfully

Bargain hunters beware. Not all EPA protocol gases are created equal, and basing your EPA protocol gas purchase solely on price may cost you in the end. Here are some things to consider when choosing a protocol gas:


How important is it to you that your gases are on spec? Accuracy is mandatory when you are measuring emissions and out-of-spec gases can cost you both time and money.


Change is in the air, quite literally. Today’s industry cannot rely on old production methods and stay competitive, or in the case of regulations, even expect to remain within the law. When you pick your EPA protocol gas, choose a supplier with a history and reputation for producing consistent and high-quality products.

Production speed

Things worth having take time, including EPA protocol gases. Never wait until your supply of EPA protocols is exhausted or almost depleted before ordering more. Avoid a runout emergency by choosing a supplier who routinely blends and ships within the EPA assay requirements and who can also stock EPA protocol gases for you.
