As one of the largest industrial and specialty gases company worldwide, Linde works to consistently provide calibration gases that meet or exceed regulatory standards for your specialty gas needs. To meet this standard, each individually produced specialty gas and gas mixture is supplied with a certificate of analysis (COA) and is attached to each gas cylinder.

The COA contains all the important information regarding the gas mixture, including the actual analytical test results for the pure product or calibration mixture. It also includes the method of analysis, the accuracy of the analysis and the reference standards used. Other details may include the cylinder and valve specifications, the volume and pressure contained, expiration dating as appropriate and proper signatures of authorization. 

Going Electronic

Paper COAs can at times can be difficult to work with. How many times have your COAs gotten lost or damaged during transit? How much time have you spent reaching out to your suppliers so they could resend COA documents? Especially during times of emergency, getting a new COA copy can cause disruptions to your processes, potentially adding incremental costs.

With lindedirect.com you can quickly and easily access an electronic version of this essential documentation and get as many copies when and where you need it. With the exception of medical gases, you can access and print COAs for any specialty gas products you purchase from Linde – immediately.
