It's the decimal places that count: Gases and their purity.

Our product portfolio ranges from conventional industrial gases to gas qualities whose minor components are in the ppm (parts per million) range. We meet these highest demands with our production at the Hörstel Specialty Gases Centre. There, we produce ultra-pure gases up to 99.9999 percent purity by volume, i.e. 6.0 quality.

Did you already know? This is the spelling of the gas purity:

Gas units are often represented in dot notation - a shortened form of the percentage. Here, the digit before the dot determines the number of "nines". The digit after the dot is the first number that differs from nine.

Examples:

Nitrogen 5.5. - purity 99.9995 % by volume (= 5 "nines", last number "5")
Oxygen 6.0 - purity 99.99990 vol.-% (= 6 "nines", last number "0")
