Low-level detection of carbon monoxide (CO) and carbon dioxide (CO₂) is critical for many applications. Restek’s methanizer (CH₄izer) allows ppb-level determination of CO and CO₂ using a cost-effective GC-FID instead of more expensive instrumentation. The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO₂ to CH₄, but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point, and the actual temperature is displayed in real time on an easy-to-read monitor. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement so you spend more time analyzing samples and less time on maintenance.
