The QC+ Point of Operation Panel contains purifier cartridges that can be quickly changed. The cartridges are removed from the panel without interruption of gas flow to the system, drastically minimizing costly instrument downtime.
Filter cartridges are of all metal or glass construction, eliminating infusion and resultant signal noise associated with filters constructed from plastics. Cartridges are quickly installed via a simple knurled retaining nut. No wrenches are needed! As many as four cartridges can be replaced in a matter of seconds, and because there is low dead volume, a minimal amount of gas system purge is required after installation.
Each QC+ filter head is equipped with an internal flow valve. This valve serves two functions. In the “down” position, gas is passed through adsorbent filter cartridges for purification. In the “up” position, the gas is diverted through the filter head. With the valve up, the filter can then be easily replaced with a fresh cartridge. But, because the gas continues to flow through the bypass valve, the need to shut down instruments is eliminated while the filter cartridges are removed. QC+ is the only GC purification system with this revolutionary “flow through/bypass” feature.
The QC+ system has a unique D-shaped cartridge top that is self-aligning into the matching slotted filter head, assuring trouble-free installations. As many as four cartridges can be replaced in a matter of seconds without exposing downstream plumbing to atmospheric contaminants.
QC+ systems are available in single-head kits or 2-,3- and 4-head panel configurations, available exclusively with 1/8 in. Swagelok fittings. QC+ panels can be wall mounted or used “freestanding.” Oxygen, water, hydrocarbons and other organics are reduced to low part per billion levels.
