* Approximate contents; actual contents will vary by concentration. Diagnostic gas mixtures are typically ordered as certified standards, but
** Contact your local Praxair representative for specific part numbers. can also be produced to meet primary standard grade. For applications
that do not require a reported analysis, such as biological atmospheres
and medical laser gases, non-certified grades are typically ordered.
