The Rise of Hydrophilic Interaction Chromatography (HILIC)
Hydrophilic interaction chromatography (HILIC) is becoming more popular. In this interview, Dr Tohru Ikegami, from the Department of Biomolecular Engineering, Kyoto Institute of Technology in Kyoto, Japan, reveals more about the evolution of HILIC, important new developments, and tips on how to get the most from this technique. |

| A Simple Cleanup Protocol Using a Novel SPE Device for UPLC-MS/MS |
In this experiment a new solid phase extraction (SPE) device, the Oasis PRiME HLB Cartridge, was used in the sample preparation of milk samples as a cleanup method for multi-residue veterinary drug analysis. Sample extraction, chromatographic and mass parameters were all optimized. This method is simple, rapid, and accurate, suitable for multi-residue veterinary drug analysis of milk.

Metabolic Fingerprinting Using GC–MS
In this new video from LCGC TV, Christian Wachsmuth from the University of Regensburg in Germany compares the performance of different ionization methods for GC–MS in metabolic fingerprinting. He also goes on to talk about how GC–MS could be applied in a clinical setting and what developments are needed for this to happen. |

Why Every Good Analytical Chemist Also Needs to Be a Statistician
Once you have mastered the terminology and symbology, the actual mathematics for the models and approaches used at the level which is useful to practicing analytical chemists is really very straightforward indeed. |

| New VICI miniPDD Helium Inonization Detector |
The VICI miniPDD (PDHID) uses about one fifth (20%) the amount of helium as the current versions, giving up only a bit of sensitivity and dynamic range. It is approximately one half the size of the D-4 series, but has nearly the same sensitivity — about 100 ppb for fixed gases. It is particularly well suited where the high cost of helium becomes a consideration.

| New ACE 1.7µm Advanced Selectivity UHPLC Phases |
ACE Advanced Selectivity Phases offer chromatographers an extremely powerful tool for UHPLC method development and are now available with ultra-inert, high efficiency 1.7µm particles. These phases offer chromatographers greater choice for alternative selectivity, without compromising stability or robustness. Available 1.7µm phases include ACE SuperC18, C18-AR, C18-PFP, C18-Amide, CN-ES and C18 and all phases are fully scalable with existing 2, 3, 5 and 10µm particle sizes.
