Laboratories, analytics, and calibration

Quality and traceability are key

● All our gas products undergo quality assurance and, if necessary, come with a certificate of analysis.

● Purity grades are usually written in two ways:

1. As a quality code, such as 5.5, where the number preceding the decimal point represents the number of nines and the last digit the last decimal point (5.5 = 99.9995% or 6.0 = 99.9999%).
2. Impurities as a percentage, such as >99.9995.

Examples:

Ethylene 2.8 means a purity level of 99.8%.
Argon 6.0 means a purity level of 99.9999%.

Accreditation is an important aspect of specialty gas production

Many of our HiQ® specialty gas facilities are ISO 9001 certified as producers, and certain facilities are independently accredited, for example, as testing or calibration laboratories according to ISO 17025:2005 standards, and ISO Guide 34. This provides the highest level of quality assurance, and we can confidently say that the methods used for certifying accredited calibration gas mixtures are accurate, consistent, documented and validated.

With our self-service solution, you can assemble mixtures of hundreds of chemical compounds. SPECIFY is a fast and user-friendly tool that provides immediate feedback on product availability, similar mixtures, and suggestions.

Follow these easy steps to create a gas mixture:

• ● Go to specify.linde.com
• ● Set the amount of components to be mixed - up to 30 components
• ● Select chemical components and mix them with the gas
• ● Select certification
• ● Choose packaging



Wait for confirmation - the platform will indicate whether the gas mixture you want can be made. Our specialty gas team will carry out the final feasibility testing and contact you with a quote.
