Common Errors in the Laboratory
We all make mistakes. The first step to correcting them is recognizing them, and learning the right way to do things. In two new short videos, Merlin Bicking talks about two common errors that chromatographers make, and how to avoid them. More... |

GC–MS Detects and Identifies Four Ozone Depleting Gases in Atmosphere
Four new ozone-depleting substances (ODSs) — CFC-1121, CFC-112a, CFC-113a, and HCF-133a — have been detected and identified in the Earth’s atmosphere using gas chromatography–mass spectrometry (GC–MS).1 The research published in Nature Geoscience compared samples collected between 1978 and 2012 to establish a clear increase in the emissions of these gases, even though CFC production has been banned globally since 1987.

The Essentials: Mixed-Mode HPLC Separations: What, Why, and How
In this excerpt from LCGC’s e-learning tutorial, the mechanisms of mixed-mode chromatography are explained, with reference to the parameters that are used to optimize selectivity and retention. More... |
UHPLC Method Development and Modelling in the Framework of Quality by Design
The goals in ultrahigh-pressure liquid chromatography (UHPLC) method development are to first find the best separation, second find the best column, and third find the most robust method in a multifactorial Design Space. Trial and error methods are not sufficient anymore and solid science based on Quality by Design (QbD) principles is required. Control strategies and continual improvements of the methods are necessary, which offer much greater flexibility in the quality control laboratories than before. Modelling tools based on QbD principles used in method development give transparency to the control of multivariable influences and achieve faster drug applications and commercial authorization by the regulatory agencies.

Enhancing Aroma Profiling of Wine with GC–TOF–MS
Nick Bukowski, Laura McGregor, and Steve Smith
This application note demonstrates that BenchTOF time-of-flight mass spectrometers coupled with GC can provide a high-performance solution for the detection and quantitation of aromatic compounds in wine extracts. In particular, we show how the ChromCompare software Smodule allows rapid identification of differences between samples, and how Select-eV variable-energy ionization capability enhances both the sensitivity and selectivity of analyses.
