2 Tubing between high-capacity gas purifier and OMI-2 How to Select PurifiersWhy use gas Purifiers ? Hydrocarbons in the carrier gas can lead to noisy baselines and irreproducible results. Moisture and oxygen canstrip phase, creating excessive bleed, damaging the GC column and shortening lifetime. Purifiers help ensure the reliable and cost-efficient performance of the GC recommendation is to use individual Purifiers to handle each of the typical contaminants. These contaminants (hydrocarbons,moisture and oxygen) are present in different impurity levels in the gases. Seldom do you find a purifier that has the correct quantitiesof each adsorbent to match the contaminants in your gases. It is better to use separate Purifiers for each contaminant and change themon a need Purifiers - These Purifiers allow a continuous monitoring of the actual gas quality that reaches the GC instrument.

3 Theygive an indication of a needed purifier change before an analytical problem is caused by insufficient gas purity. We strongly recommendthese indicators to ensure a reliable delivery of pure carrier indicators (blue beads) - Most moisture Purifiers that contain blue beads will show a color change at moisture levels above50ppm. They can be regenerated under certain indicators - Purifiers such as the OMI line of Purifiers indicate the presence of oxygen in your carrier gas. Oxygen indicators aredesigned for use primarily as an indicator. They are not designed for use as the main oxygen trap when purifying gas of low Purpose Purifiers - These Purifiers are designed for specific Purifiers - Purifiers such as the SUPELCO helium purifier and the UOP mat/sen are designed to produce high purity Helium carriergas for use with GC/MS instruments.

4 This results in greater sensitivity of the Dioxide Purifier - This purifier is used with techniques involving FTIR, IR, Total Organic Carbon (TOC) and other detectorssensitive to Carbon Dioxide (CO2). We offer a purifier that removes CO2 and shows a color change. The reaction of CO2 with theabsorbent forms moisture. We recommend the use of a moisture-removing purifier downstream of the CO2 -removing information is available in SUPELCO Bulletin 918 (T197918) on Selecting Purifiers for Gas DeliveryGas PurifiersGasChromatographySUPELCO301 Order: Technical Service: Web: Purifiers for Hydrocarbon RemovalMAXIMUM FLOW &CAPACITYSTATEDNAME OFCARRIER GASESCONTAMINANTSINLET PRESSURE(GRAMS HCLIFEPURIFERPURIFEDREMOVEDPRODUCT DESCRIPTION2(CC/MIN) (PSIG/BAR)X 75%)3(CYLINDERS)1 Supelcarb HCHe, H2, N2, Ar/CH4,C3 and higher120cc tube2000250 " 244481/4" 24449750cc tucbe10,000250 " 245641/2" 24565 Supelpure HCHe, H2, N2, Ar/CH4,C4 and higher120cc tube2000250 " 22445-U 1/4" 22446750cc tube10,000250 " 245181/2" 24519 UOPHeO2, H2O, CO2, CO364cc tube500250 Gashalocarbons,1/8" 22680-U 1/4" 22681 Purifierhydrocarbons,sulfursGas DeliveryGas PurifiersGas Purifiers for Moisture RemovalMAXIMUM FLOW &CAPACITYSTATEDNAME OFCARRIER GASESCONTAMINANTSINLET PRESSURE(GRAMS H2 OLIFEPURIFERPURIFEDREMOVEDPRODUCT DESCRIPTION2(CC/MIN) (PSIG/BAR)X 75%)(CYLINDERS)
