The HiQ 60 range of calibration gases includes pure gases and non-reactive gas mixtures that have an extended 60 month (5-yr) shelf life and flat-line guarantee, allowing for greater reliability in the accuracy of instrument measurement and longer-term usability of gas. Previously, gas suppliers had offered product expiration guarantees of 36 months, with many products available with only 12 or 24 months of shelf life. The HiQ 60 pure gases include Ar, CO2, He, H2, N2 and synthetic air. — Linde Gases, Munich, Germany
