Hello it is almost impossibnle to get any gas absolutely pure as small traces will always creep inbut other wise you are right 99,999 is more 'pure' than 99.995but we are talking about 10 to 50 parts per million here so absolutely tiny amounts of oxygen it does come down to what you want the gas for

please let me know
Expert:  Matt replied 1 year ago.
Hello 99.995 will be more than adequate for all of those purposesas bacteria needs an oxygen environment of at least 500 parts per million to breed and 99.995 is only 10% of that
