How to get speed in HPLC

Fast HPLC

Couple of days ago, I mentioned on Chromatographer’s facebook page article by Peter Carr about speed in HPLC published in Analytical Chemistry. There are two parts in the article: (i) critical comparison of different approaches how to reach speed in HPLC and (ii) theoretical background of speed and efficiency optimization in high performance liquid chromatography.

Communication problem with Chromeleon 6.8

Dionex Logo Usually, I leave instrument’s computer up and running for long periods of time. No surprise that after several weeks there is significant amount of Windows Updates ready for installation. This week I had to reboot my system (Dionex Ultimate 3000) and during this occasion several new updated were installed.

After that I started to have problems with connection to the Chromeleon server.

One column fits all – Hypercrosslinked monoliths

One column fits all was title of my poster presented at HPLC 2010 in Boston that described the preparation and characterization of hypercrosslinked monolithic stationary phases and their application in several chromatographic modes. We summarized poster’s results and submitted them as a paper in Journal of Chromatography A.

My HPLC books

Today, I would like to describe my favorite chromatographic books: from one I bought even before I (really) knew what chromatography is to one which has chapter with my name on it.

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, including the comparison of attendance this year vs. last year, percentage distribution of individual topics, as well as plenary lectures, major applications and usage of various detection techniques.
