Past, Current, and Future Directions in Supercritical Fluid Chromatography
October 2nd 2013Supercritical fluid chromatography has become a viable option for the separation scientist in diverse areas, and the field now seems more adequately described as an extension of HPLC, or perhaps as "carbon dioxide–based HPLC".
The Top 10 HPLC and UHPLC Column Myths: Part 1
October 1st 2013In any field, there are "misconceptions" or "myths" that arise and are perpetuated and passed on to the next generation. These myths are often driven by a lack of understanding of the real issues by practitioners. In the first of a two-part feature from Ron Majors, the top 10 high performance liquid chromatography (HPLC) column myths are presented and attempts are made to demystify them by offering some evidence that they are untrue. This part will feature myths 10 to six.
Carbon Nanotubes: Applications in Chromatography and Sample Preparation
The latest applications for carbon nanotubes in chromatography and sample preparation are outlined.
The application of gas chromatography (GC) combined with atmospheric pressure chemical ionization mass spectrometry (GC–APCI-MS) and with supersonic molecular beam ionization mass spectrometry (GC–SMB-MS).
