Split Later and the Case of the Infinite Dilution Tube
Two concepts that were coined by Tony Taylor’s good friend John Hinshaw during a recent CHROMacademy webcast are presented together on sample introduction for capillary gas chromatography. Taylor provides a summary of what he learned during the webcast, and offers tips for successful trace analysis. More...
Convert from Helium to Hydrogen as a GC Carrier Gas
Learn how to convert from Helium to Hydrogen as a GC carrier gas, Hydrogen is much less expensive, can provide more rapid separations at lower temperatures than Helium, and provides longer column life. Hydrogen gas is obtained by the electrolysis of water and many laboratories supply it to the GC via an in-house H2 generator. DOWNLOAD this easy to use STEP by STEP Guide.
