LDCRYO
CRYOGENIC TRAP SYSTEM FOR GC HELIUM CARRIER GAS PURITY
TYPICAL INSTALLATION
The LDCryo system comes with a single trap or with dual trap configuration. In its most common dual trap configuration, both traps are mounted in parallel and can be replaced periodically when the trap is blocked. The LDMPS pressure monitoring system monitor the pressure at its inlet and outlet to ensure the pressure is high enough to feed the gas chromatography system carrier gas. If the pressure comes low, then the LDPMS gives an alarm, and the operator must isolate/regenerate the default trap and open the valves of the backup trap to keep flowing gas through the GC system.
The LDCryo system must be installed with our LDP1000 or LDP2000 heated gas purifier series. The heated gas purifier must be installed before the LDCryo to remove most of the impurities (excluding Argon). This way, it ensures to keep the cold trap system clean from high level contaminants and then ensure its lifetime is extended as long as possible.
The complete system is mounted with the LDASS automatic switchover system to keep the Helium source permanent without interruption.
