The optional Purge Circuit, available on the S4000, 4040, and 4020 systems, allows you to send a purge gas through the system from a single dedicated input port. This process effectively helps flush residual gases from the gas path.

Regular use of the Purge Mode is a simple, low-cost way to maintain the cleanliness and performance of your system. It helps extend the life of the instrument, improves safety, and ensures consistent operation. Purging is especially beneficial when switching between reactive gases, after periods of system inactivity, or following the use of toxic or corrosive gases.

Investing in regular purging pays off—keeping your system cleaner, safer, and more reliable for years to come.
