Top Story: The Best of Both Worlds: LCxLC in Food Analysis
Comprehensive two-dimensional liquid chromatography (LC×LC) offers much higher peak capacities than single dimension separations. The degree of orthogonality between both dimensions is a critical factor for obtaining higher values for peak capacity. This review illustrates the benefits of LC×LC in food analysis and discusses the combination of LC modes used in the two dimensions, and the nature of the samples analyzed. |

| Automated Solid Phase Extraction of Base, Neutral and Acid Semi Volatiles in Waste Water |
Solid Phase Extraction has long been used for the analysis of semi-volatile organics in clean matrices. Due to the unique challenges inherent with waste water matrices adhered to LLE protocols. Advances in packing materials and the new automated FMS TurboTrace ABN SPE extraction system are now making extractions of difficult matrices commonplace for SPE.  View the prerecorded webinar to learn how improve the quality and throughput for your laboratories extractions. |

Flavour and Fragrance Analysis: Wondrous Vanilla
There are over 100 different types of vanilla, all characterized by different aroma profiles. Stephen J. Toth from the State University of New Jersey in the USA investigated this further in his doctoral dissertation to find a unified method to determine volatile and semi-volatile organic compounds in vanilla pods and extracts, and his work is discussed in this short article. |

HPLC Extra Column Volumes
It is of particular importance to reduce extra column volumes when using small volume columns or UHPLC. However, where do these extra column volumes come from, how can they be minimized, and what effect do they have on chromatography? |
