Modern narrow bore columns have made chromatographers lazy when it comes to stationary phase selection. Here’s how getting back to the basics in gas chromatography by using selectivity can address challenging separations and reduce analysis time.

Today’s laboratories have to deal with an increased number of samples; throughput is a progressively more important factor. Solutions have been presented, for example, highly efficient narrow bore columns. However, operating 0.10 mm ID columns demands specific instrumentation and skills. Moreover, use is limited by sampling, loadability, durability, and the measurement of “fast” peaks. The use of 0.15/0.18 mm ID capillaries has been better accepted.
