Finally! A blog update. After almost six months I have something to tell. Even though only shortly. I am going to describe my past chromatographic months in one of the next posts. Until then, I would like to wish you nice year 2012 and especially good health. Everything else will come along.
During the time I spent in Berkeley I had the honor to work on the beginning of the project leading to the portable system for highly sensitive multi-dimensional chemical analysis. This work included hyphenation of NMR with liquid chromatography separation using organic polymer monoliths. I have to admit, it was my first touch of NMR [...]
Last year, I summarized my HPLC 2010 notes after the meeting. This year I would like to share with you a list of talks I am going to see. If you like, you might share your favorite talks presented on HPLC 2011 (link to program at HPLC2011.com). Sunday – Opening Ceremony No discussion. You have [...]
International Science Olympiad for high school students from 20 European countries. One particular example in an analytical chemistry part focuses on the iodometric titration with 3 maximum available points. The organizers decided to use “all or nothing” approach. Either you have a correct result with maximum points or you have made …
Generally, methacrylic acid is used as a charge-bearing agent for generation of electroosmotic flow in capillary electrochromatography. However, methacrylic acid has a significant effect on the morphology of the monolithic stationary phases based on styrene – divinylbenzene system as showed recently by group in Prague. The monolithic material prepared without methacrylic acid in the polymerization [...]
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. [...]
Last year, I tried to use “chromatographic” New Year’s greeting for first time. It was kind of easy. This year, I would like to continue with this tradition and – additionally to strip presented below – I would like to wish you good health and welfare in the upcoming year. May the bad stuff from [...]
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 [...]
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. Hypercrosslinking modification is not a new technique. [...]
