Exploring High-Throughput Sample Preparation

What is high-throughput sample preparation? Do modern extraction methods adequately address the issue of time? How can we address the analytical need for speed?

Developments in the Preparation of Organic Polymer Monoliths

Developments in the preparation of organic polymer monoliths suitable for the separation of small molecules in the isocratic mode are described and the main factors affecting column efficiency are identified.

Pyrolysis–GC–MS for the Identification of Polymeric Materials

The pyrolysis–GC–MS method enables direct analysis of solid or liquid polymers without sample pretreatment, as illustrated here for various materials, including a dental filling material and a car wrapping foil.

LC Troubleshooting

UV detectors are the most common LC detector, and perhaps the most reliable ones. But they are not without problems. To solve any issues, it helps to understand a few things about how the detector cells are designed. John Dolan provides some guidance.

Perspectives on Superficially Porous Particles

This review provides an updated overview of the theory behind the success of SPP technology, trends, benefits, and limitations.
