Chromatography
This month Lab Manager poses four questions on GC usage, likes, and dislikes to a panel of five experts
Process GC involves the deployment of rugged, reliable gas chromatographs in demanding process environments. Where traditional sampling and analysis occurs off-site in analytical laboratories, process GC brings the “lab” to the production site, providing realtime product analysis.
The proverbial “ounce of prevention” goes a long way toward preventing serious GC downtime. Keeping up with routine maintenance is the secret to ensuring that scheduled maintenance downtime occurs on the lab’s terms, not by fickle fate.
Thermo Fisher’s Eric Phillips, describes the adoption of MS detectors in GC as a “technology shift” that began with single-quad MS as an alternative to standard GC detection modes.
Capillary columns have changed the face of GC since their introduction about 35 years ago. The most obvious change involves resolving power: up to 50,000 theoretical plates on a 30-m capillary versus 1500 on a six-foot packed column.
Despite steadily losing ground to high-performance liquid chromatography (HPLC) over the years, particularly for polar compounds, gas chromatography (GC) remains one of the more rapid and efficient chromatographic methods.
New Xplorer plus electronic pipettes were specially designed to optimally support you and your work. With a new intuitive operating concept and additional modes, it sets new standards for simplicity, precision and reproducibility.
Problem: In most UHPLC/ HPLC applications, the buildup of sample and mobile phase contaminants at the head of the chromatography column can cause detrimental effects.
Today, the number of distinct GC column stationary phases has grown
