The LCGC Blog: An Open Inquiry Model for Science Education
According to LCGC blogger Kevin Schug, there is a shortcoming in our current educational system: too much rote learning, and not enough time given to let science-minded students explore a topic. He says that when students ask their own questions (not ones given to them by instructors), they become more invested in finding the answers. |

Incognito: How Dare You! The Emotive Matter of Questioning Chromatographic Integration
Have data systems improved to the point at which we have overcome major barriers? Or have we been so brain-washed by the regulators that we must avoid reintegration (especially manual integration) at all costs, which has led to a reluctance to apply legitimate adjustments to errors created by our data systems? |

Technical Tip: Static Headspace Sampling
Static headspace sampling is typically used for the determination of volatile and semi-volatile analytes in liquids and, more rarely, solid matrices. Application examples include the analysis of alcohols in blood, residual solvents in pharmaceuticals, flavours and taints in food and beverages as well as fragrances in perfumes and detergents. |

TSKgel Amide-80 is now available in 2 micron particle size. For years, TSKgel Amide-80 columns are used successfully for HILIC separations of polar compounds such as saccharides, glycans, oligosaccharides, or peptides. The amide chemistry is particularly popular for glycosylation analysis of proteins. The new small particle size columns deliver higher resolution and peak capacity and are ideally suited for UHPLC and UHPLC-MS.
