Set gas purity from the process requirement

Purity is part of a quality specification. Confirm the measurement basis, sampling location and finished-product requirements together.

01Read the process specification first

Processes that all use nitrogen for protection can have different limits for residual oxygen, moisture and particles. A purchasing specification should list the relevant limits and units individually instead of using a number of nines to describe every quality requirement. An analysis at the generator outlet must also be related to conditions at the point of use. Pipework condition and sampling arrangements belong in that review.

02Validate settings against the product outcome

Food packaging illustrates the difference between nitrogen supply purity and residual oxygen inside the finished package. Parker's guidance explains that air introduced during the filling process and other factors can affect final package oxygen content. Establish the product's package acceptance criteria first, then use machine cycle data and practical trials to determine the gas supply requirement. The highest nominal supply purity is not automatically the most useful starting point. This brief explains how to express requirements; it does not replace quality validation for a food, electronics or chemical process.

  • Identify each measurement: residual oxygen, dew point or moisture, and any other process-limited constituent.
  • Identify the measurement point: generator outlet, distribution endpoint or finished package.
