Is Your Method from Mars?

Sometimes, the conditions specified in legacy liquid chromatography (LC) methods seem like they come from a different planet. In this instalment of "LC Troubleshooting", we look at which conditions to keep, and which ones to let go of. Read more

Exploring the Efficiency of Various Extraction Approaches for Determination of Crude (4-methylcyclohexyl)methanol (MCHM) Constituents in Environmental Samples

Crude (4-methylcyclohexyl)methanol (MCHM) is a chemical contaminant that must be monitored in fresh water environments, because of significant health risks to surrounding human populations. A new method for MCHM analysis was developed using solid-phase microextraction (SPME) and thin film microextraction (TFME) combined with GC–MS. Both methods achieved limits of quantitation lower than standard methods using SPE. Read more

Comprehensive Fingerprinting of High-Quality Food Products Using GCxGC–TOF-MS

The strategic role and potential of comprehensive two-dimensional gas chromatography (GC×GC) combined with time-of-flight mass spectrometry (TOF-MS) and pattern recognition using template matching for data processing to unravel the quality traits of high-quality food products is discussed. Practical examples dealing with high-quality cocoa and extra-virgin olive oil are described. Read more
