Getting the Best Repeatability from Your Quantitative Gas Chromatography

I'm often asked "what reproducibility should I expect to get from my [insert instrument manufacturer and model]?" So, most folks are referring to the repeatability aspects of precision, as in: "what relative standard deviation (usually expressed at %RSD) for peak area or quantitative result should I be able to achieve from repeat injections from a single vial of sample?"

IonBench is a manufacturer of LC/GC/MS and elevating UHPLC benches. MS ionBenches integrate MS peripherals, a built-in vacuum pump noise reduction enclosure and protect turbomolecular pumps by reducing vibration by 99%. Solidly built lockable casters simplify moving the system. LC Elevating IonBenches, on caster wheels, can be easily lifted up or down for a convenient and safe access to the top of your UHPLC.

Peter Schoenmakers on Combining Space-Based and Time-Based Separations and 3D LC: Is It Practical?

Space-based and time-based separations are often a preferred approach. Peter Schoenmakers from the University of Amsterdam discusses how they can be combined and the benefits of this approach. He also discusses the complexities of 3D LC. Read more
