Abstract

Compositions comprising at least 99.99% gaseous carbon monoxide, as well as pressurized cylinders containing such compositions. The compositions can have a Fe(CO) 5 content less than 1 ppb, a Ni(CO) 4 content less than 10 ppb, a water moisture content less than 5 ppm, and, a CO 2 content less than 2 ppm. Gaseous carbon monoxide purities of 99.998% and 99.999% are achieved by removing residual air from the gaseous carbon monoxide.
