Because of the high cost of HPLC columns, there are numerous ways to find out which column(s) might best be of use for an intended but new separation. If some of the components are known, then the literature or manufacturers’ websites can be consulted. This might take some time, but the research of others can save both time and money in your own work.

Pre-formulated buffers for pH gradient have greatly simplified the development of ion exchange chromatography (IEX) of monoclonal antibodies (mAbs). Three features make this simplification possible.

Soft ionization remains a relatively underused technique for GCMS, despite its ability to provide improved confidence in the identification of a range of challenging analytes. But there is now a new approach that makes it possible to lower the energy of electron ionization to achieve soft ionization, without the disadvantages with which it has historically been associated.

Mass spectrometry (MS) is the workhorse of analytical chemistry. It performs the analysis of the sample, making MS equipment an essential part of the analytical instrumentation market. A recent shift in the laboratory landscape, however, is forcing a change in the size and functionality of mass spec equipment.

Researchers at Purdue Univ. have pioneered a separation technique that can be used in everything from homeland security and law enforcement to drug discovery and biomedical applications. The technique, called slug flow microextraction, makes it possible to quickly detect the presence of drugs or monitor certain medical conditions using only a single drop of blood or urine.
