How is your gas 99.75%? Are you falsely marketing an extra .25% purity to give yourself a competitive edge by lying to the industry about an extra .25% purity? You sell instrument grade gas like everyone else who sources through diversified and their established distribution chain, and 99.5% purity is the standard.
Also, regardless of how clean you get your tank before every refill, you’re still filling the tank with .5% of unwanted compounds so regardless if you clean before every refill, you should be distilling your gas to insure product quality. Telling ppl otherwise is bad advice.
The contaminated gas is coming from Cortland Energy because they are selling industrial grade gas. We’ve got test results of their gas containing C6+ contaminants. I believe they distribute to thc gas, elite solvents, gas logix, and a few other welding supply stores in NorCal where a lot of this seemed to have started to get noticed.
