Gas Management for Your LabA clean gas stream is critical to the quality ofyour GC analysis and the reliability of youranalytical results. Carrier gas must contain lessthan 1 ppm of oxygen, water vapor, and othertrace contaminants for stable baselines on alldetectors and to prevent column degradation,shortened column lifetime, and increasedstationary phase bleed. Clean fuel gases andmakeup gases are also essential for stable detectorbaselines. Your gas management system mustdeliver a high-purity gas stream from your sourceto your instrumentation without introducingcontaminants. Restek offers the products youneed to assure a clean, leak-free gas managementsystem. If you need assistance in configuring yoursystem, contact your Restek representative todiscuss your application requirements.Questions to consider when building yourgas management system:1. What gases do you require and at what purity?2. What flow rates and/or pressures are required?3. Are you using gas generators or high-pressure cylinders?4. What type of tubing and fittings are needed to buildyour system?5. What type of gas purifiers should you install in your system?Once the components needed for your system are established, youwill need to determine the most appropriate way to configure your gasmanagement system. Figures 1 and 2 are typical configurations: Figure 1illustrates a system that uses gas generators and Figure 2 shows a systemconfigured for use with high-pressure cylinders.Figure 1: Gas management system configuration using gas generators.Zero Air GeneratorAirCompressorInlineRegulatorInlineRegulatorsShut-OffValveShut-OffValveIndicatingMoistureTrapShut-OffValveFIDShut-OffValveIndicatingMoisture TrapHydrocarbonTrapNitrogen GeneratorHydrogenGeneratorHigh PurityHydrogen GeneratorShut-OffValveIndicating Oxygen TrapFlashArrestorIndicating Moisture TrapShut-OffValveFigure 2: Gasmanagement systemconfiguration usinggas cylinders.Air CylinderDual-StageRegulatorsShut-OffValveShut-OffValveFIDNitrogen CylinderFlashArrestorHydrogen CylinderDual-StageRegulatorsShut-OffValveShut-OffValveCarrier Gas CylinderIndicating Moisture TrapHydrocarbonTrapIndicating Oxygen Trap2 www.restek.com

Gas Cylinder AccessoriesWhen using high-pressuregas cylinders there are anumber of accessories thatshould be used in order tosafely handle and installcylinders in your gasmanagement system.Handling Gas CylindersWhen using high-pressure gas cylinders there are a number of accessoriesthat should be used in order to safely handle and install cylinders in yourgas management system. Dropped gas cylinders are very dangerous and canbecome flying projectiles if the cylinder valve is damaged. A cylinder holderwill safely secure your cylinder to a wall in your lab, preventing it fromaccidentally toppling over and discharging its contents.Manifolds and Switchover SystemsHigh-purity automatic switchover systems provide a continuous supply ofhigh-purity gas to your gas management system. Continuous gas supplyis achieved by setting the two regulators at slightly different pressures anddischarging one side of the system at a time. This allows for the replacementof a depleted gas cylinder without interrupting the gas supply.Description qty. cat.#WALL MOUNTED CYLINDER HOLDERSCylinder Holder, Wall Mounted, Single ea. 21333Cylinder Holder, Wall Mounted, Double ea. 2340021333Cylinder Holder, Wall Mounted, Triple ea. 23401Cylinder Holder, Wall Mounted, Quadruple ea. 23402TOOLS21321Cylinder Valve Wrench ea. 21321Universal Cylinder Wrench ea. 21322Flexible Stainless Steel Hose, 1 /4" Female NPT, 36" ea. 21339Flexible Stainless Steel Hose, 1 /4" Female NPT, 18" ea. 21340FLASH ARRESTORS21334Flammable Gas Flash Arrestor, Brass Body, 1 /4" NPTF ea. 21334PROTOCOL STATIONS*Chrome-Plated Brass, CGA 580 (N2, He, Ar) ea. 21347Chrome-Plated Brass, CGA 350 (H2, P5) ea. 21348Chrome-Plated Brass, CGA 590 (Air) ea. 2134921347Stainless Steel, CGA 580 (N2, He, Ar) ea. 21327*Pressure regulator not included.

Pressure RegulatorsThe job of a pressure regulator is simple: it reduces the pressure of a gas source to a safe working pressure. However, there aremany variables that need to be considered when choosing a pressure regulator. Does your application require a stainless steelor brass regulator? Do you need a single or dual stage regulator? What type of gas are you regulating and what is the desireddelivery pressure? Your choice in a pressure regulator will depend on your application and where it is placed in your gasmanagement system.Ultra-High Purity RegulatorsRestek offers ultra-high purity (UHP) pressure regulatorsin brass and stainless steel bodies. The UHP brass pressureregulators are the best choice for gases with a purity of99.995% or greater, such as those used in carrier and fuelgas supplies. These pressure regulators feature a reducedinternal dead-volume relative to stainless steel bodies. TheUHP stainless steel pressure regulators are the standard forultra-high-purity and corrosion-resistant pressure regulation.Dual-Stage Pressure RegulatorsA dual-stage pressure regulator provides more precisepressure control by reducing the gas source pressure to thedesired delivery pressure in two steps. They are recommendedfor supplying gas where constant delivery pressureis critical, especially if your gas source is a high-pressurecylinder. As the cylinder gas is used, the inlet pressure tothe regulator from the cylinder decreases. A dual-stageregulator compensates for the decrease and maintains aconstant delivery pressure; whereas, a single-stage regulatordoes not.Single-Stage Pressure RegulatorsA single-stage pressure regulator reduces the pressure ofthe gas source to the desired delivery pressure in one step.It does not provide the precise control of delivery pressurethat can be achieved with a dual-stage pressure regulator.Single-stage pressure regulators should be used for applicationswhere you can monitor and regulate the pressuredownstream.In-Line RegulatorsLine regulators are single-stage pressure regulators that are usedto provide point-of-use pressure monitoring and control. Thesepressure regulators are installed directly into gas lines, immediatelybefore your instrumentation, to ensure the appropriategas pressure is being delivered to your instrument. A dual-stageor single-stage pressure regulator should always be installedupstream of the in-line regulator to ensure adequate pressurecontrol.Pressure Regulator ConnectionsRestek ultra-high purity pressure regulators come with a varietyof different connection fittings for attachment to different highpressuregas cylinders. In the United States, Compressed GasAssociation (CGA) fittings are used and designed for differentgas service. In the European Union, German Institute forStandardization (DIN) fittings are used to make these connectionsand British Standard (BS) fittings are used in the UnitedKingdom.

Tubing and FittingsPre-Cleaned Tubing from RestekThe integrity of a gas management system can becompromised by using tubing that has not been precleaned.Residual dirt, machine oil, and polycyclic aromatichydrocarbons from the manufacturing process often foundin different types of tubing will lead to problems later on.Restek offers pre-cleaned copper and stainless steel tubing forplumbing your gas management system.TubingThe best choice for plumbing your gas management system isstainless steel tubing. Copper tubing can be used as well, andRestek offers both types pre-cleaned and ready to use. Type304 stainless steel tubing is the most commonly used varietyof stainless steel tubing. Copper tubing is the most economicalchoice for plumbing your gas management system.FittingsWhen assembling your gas management system, all ofyour connections should be metal-to-metal connections.This ensures a leak-free connection, which is importantfor preventing contaminants from entering the gas stream.O-rings, gaskets, and sealing reagents should be avoided whenplumbing your system to avoid contamination of the tubingand gas chromatograph. Swagelok® compression fittings areideal for making your connections, and both stainless steel andbrass fittings are offered in ¼" and ⅛" sizes.Setting Gas Flows and Checking for LeaksOnce your gas management system is assembled itshould be checked for leaks. Leaks allow moisture,oxygen, and other airborne contaminants to enter yoursystem, as well as accelerating the consumption your gassupply. Detecting leaks with soap-based liquids shouldbe avoided as they can contaminate your gas streamand gas chromatograph. The Restek electronic leakdetector is the ideal accessory for inspecting your gasmanagement system for leaks. The Restek leak detectorcan be used to determine if your system is leakinghelium, hydrogen, argon, and even nitrogen.Once you have determined that your system is leak-free,you can set your gas flows with the Restek ProFLOW6000 electronic flowmeter. This flowmeter provides anaccuracy of ± 2% and measures volumetric flow ratesfrom 0.5 mL/min up to 500 mL/min. The ProFLOW6000 flowmeter is even Ex rated so that it can be usedto measure flow rates of flammable gases, such ashydrogen.Need help selectingtubing and fittings?Contact your local Restek representative or ourTechnical Service group at support@restek.comor 1-814-353-1300, ext. 4.10 www.restek.com
