Gas Clean filter

Installing an Agilent Gas Clean filter removes contaminants, ensuring highest quality, leak-free gas flow through the system while maintaining flow path inertness and column integrity. Highly sensitive indicators provide maximum instrument protection.

EICs (32 m/z) for O₂ showing a comparison of balloon grade (99.99%) He (with and without a Gas Clean filter) and higher grade (>99.995 %) He (without filter). Using a carrier gas filter with balloon grade He dropped the O₂ abundance to levels lower than the higher grade He (>99.995%) without a filter.

Gas Clean sensor

(available for the 8890 and 8860 GC systems)

• Monitors the chemical indicators, alerting you through the touch screen and software when a filter is saturated and needs replacing
• Replacing the filters when they have reached absorption capacity ensures maximum protection of the GC inert flow path and GC columns

Ultra Inert inlet liners

Agilent Ultra Inert inlet liners, with or without glass wool, are certified to provide low surface activity and highly reproducible sample vaporization. These liners facilitate best-in-class delivery for active analytes.

Using glass wool can trap nonvolatiles and extend column lifetime. But improperly deactivated liners and glass wool can result in loss of analytes due to active sites.

Inert flow path split/splitless inlet

Portions of the split/splitless inlet that come in contact with the sample undergo the same proprietary deactivation treatment as the Ultra Inert gold seals and UltiMetal flexible ferrules to provide a continuous inert surface throughout the flow path.

Ultra Inert gold seals

Ultra Inert gold inlet seals are manufactured by applying Ultra Inert chemistry on top of gold plating. This process reduces active analyte adsorption while ensuring a leak-free seal.

UltiMetal Plus flexible metal ferrules

Agilent UltiMetal Plus flexible metal ferrules are the only ferrules with a deactivated surface that maintains the inertness of the GC flow path—critical for the detection of trace analytes.

Inert capillary flow technology (CFT)

Inert CFT provides increased GC system flexibility while making reliable, leak-free, capillary connections.

• Purged ultimate unions enable backflushing of high boilers in heavy matrix samples, eliminating the need for postrun column bakeout—shortening run times and extending column life
• Flow splitters and Deans Switch facilitate the use of multiple detectors, peak cutting, and multidimensional GC analysis for increased resolution of trace compounds in complex matrices

Ultra Inert GC column

GC column inertness is critical as these columns contribute toward the largest surface area within the flow path. Every Agilent J&W Ultra Inert GC column is rigorously tested to ensure consistently high inertness and low bleed, for optimal delivery of analytes to the detector.

Complete flow path comparison

If only 10 sample molecules are injected on a system that has 10 reactive sites, 100 % of them could be lost to the reactive sites in the system. The end result: even though reactive analytes of interest are injected, they will never be detected if they are lost on reactive sites in the GC flow path. The impact of “nondetects” can be profound.

Agilent J&W column smart key

(available for the 8890 GC system)

Smart ID keys provide information on column, configuration, age, number of injections, use, and temperature limits. Default parameters for configuration minimize error and facilitate easy method development.

Self tightening column nut

While not directly part of the GC flow path, Agilent Self Tightening columns nuts provide a leak-free connection. Their innovative spring-driven piston continuously presses against the ferrule, maintaining a leak-free seal—critical to the integrity of the GC flow path.

FID/NPD jets

The new detector jets:

• Enable easier column installation and jet replacement, reducing the risk of column damage
• Do not have thread lubricant, reducing the risk of contamination
• Are made of stronger material, reducing the risk of deforming, galling, bending defects
• Universally fit all GC platforms, and both capillary column and packed column detector body

Inert ion source

Analyte breakdown products can be indicative of active sites in the detector, which can compromise data. An inert ion source ensures the integrity of your analytes reaching the detector. In addition, the Agilent JetClean self-cleaning ion source utilizes carefully controlled hydrogen flow to further reduce or prevent contamination buildup, significantly extending the maintenance-free operation time periods.

IDP-3 oil-free vacuum pump

While the IDP-3 oil-free vacuum pump is not directly part of the GC flow path, it ensures reliable performance of the MS detector—critical for accurate reproducible results. Agilent IDP-3 pumps are oil-free, providing a quieter and cleaner laboratory environment compared to standard oil rotary vane pumps.
