HPLC 2010 flashbacks Vol. 2

HPLC 2010 flashbacks Vol. 2

When two do the same thing, it’s not always the same. In the last issue of LCGC North America, Ronald Majors summarized his highlights of HPLC 2010. In my HPLC 2010 flashbacks I focused exclusively on oral presentations I have attended during the meeting. Ronald Majors summarized whole symposium in a detailed and comprehensive way, [...]

New trends in analytical chemistry

Couple of days ago I wrote about September Discussion group organized by CASSS International separation science society. As I promised I made notes and I would like to share them with you now. Although I expected slightly different format of meeting (selection of few topics and their detailed discussion with the attendants) I was able [...]

HPLC 2010 flashbacks

HPLC 2010 flashbacks

As I mentioned several weeks ago, there was an international symposium on the separation science – HPLC 2010 – held in Boston last week. It was my second North American conference (together with San Francisco 2006) and third in total (plus Stockholm 2005). Allow me to summarize my remarks I made during the lectures I [...]

Four directions how to improve monolithic stationary phases

Four directions how to improve monolithic stationary phases

Georges Guiochon pointed out in his excelent reivew about monolithic stationary phases four directions from which we can expect a serious improvement in (monolithic) columns performance. High temperature chromatography High temperature chromatography, which causes a reduction in the viscosity of the mobile phase. So far, monolithic stationary phases have not yet been used at high [...]

Separation of small molecules on organic polymer monoliths

Separation of small molecules on organic polymer monoliths

Because of lack of small pores it is difficult to separate small molecules with polymer monoliths in isocratic mode. We have prepared monolithic capillary columns and then hypercrosslinked them to afford a monolith containing an array of small pores [1].
