Gas Clean Filter Supplies from Agilent
The Agilent Gas Clean Filter System delivers clean gases, reducing the risks of column damage, sensitivity loss, and instrument downtime. Inserting a Gas Clean Filter System in the gas line immediately before the instrument inlet greatly reduces the level of impurities, thus improving trace analysis. Contaminants entering your GC column will also be reduced, which is critical for high temperature analysis and essential for longer column lifetime.
Replacing the filters when they have reached absorption capacity ensures maximum protection of your GC columns and analytical hardware. The sensitive indicators change color, alerting you that the filter needs to be replaced.
A Gas Clean Filter System allows you to use 99.996% (4.6) pure helium instead of the more expensive 99.999% (5.0) or 99.9999% (6.0) grade, while still yielding high quality analytical results. The expected cost savings are 30%.
The Agilent Gas Clean Filter system ensures superior gas purity by removing contaminants such as moisture, oxygen, hydrocarbons, and carbon dioxide. Installing a filter in the gas line before the instrument inlet significantly reduces impurities, enhancing trace analysis and improving the efficiency and accuracy of your GC system. By preventing contamination, these filters help extend column life, maintain sensitivity, and minimise instrument downtime.
Beyond optimising GC performance, the Agilent Gas Purification system enhances operational and cost efficiency. Its tool-free, self-sealing design allows effortless filter replacement, while the integrated Gas Clean Sensor (compatible with 8860/8890 and Intuvo GCs) provides real-time monitoring and alerts when replacement is needed. Agilent Gas Clean Filters offer a cost-effective solution, enabling up to 30% savings by allowing the use of 99.996% (4.6) helium instead of more expensive grades without compromising analytical quality.
