Carbonyl Trap
Remove nickel carbonyls from CO flow
Purification of CO flows from nickel carbonyls for catalysis reactors and electrochemical cells.
Leiden Probe Microscopy offers a solution to remove nickel carbonyl impurities naturally formed in nickel-containing CO cylinders and tubing. Nickel carbonyls can be contaminants for catalytic reactions involving CO.
01 Nickel-carbonyl-free CO flows
Nickel-carbonyls are formed in carbon monoxide gas cylinders and tubing and can contaminate reactors or electrochemical cells. This trap is design to ensure contamination-free CO flow to the reactor.
02 Heated copper stage
On moderate heating, Ni(CO)4 decomposes to carbon monoxide and nickel metal. This thermal decomposition commences near 180 °C and increases at higher temperature. The copper stage of the carbonyl trap can be heated up to 375 °C to decompose the carbonyls. To avoid re-formation of the carbonyls, the high-temperature stage of the trap and internal tubing is constructed out of pure copper.
03 Particle filter screen
An additional 15 µm filter ensures the CO flow is also free from residual contamination before reaching the reactor or the cell.
04 Portable solution
With its compact footprint and its lightweight, the carbonyl trap can easily be moved from one experimental setup to another.
