Chromatography Today is a magazine very much like LC.GC, publishing manuscripts on new developments in the field of gas and liquid phase separations. Manuscripts may be logo chromatography todaycommunications on application of GC and HPLC in actual hot fields in the market, about new developments in instrumentation for GC and HPLC, data evaluation software, columns, and consumables for analysis and sample preparation and about hyphenation with mass spectrometry and other detection systems. The magazine also accepts more elaborate papers about progress in separation science and tutorial style manuscript explaining new techniques without too much depth to the readership of Chromatography Today. 

The editor of Chromatography Today has asked me to arrange a focus issue on CE and CE-MS. A number of my peers have contributed to the focus issue. The focus manuscripts will be part of the digital issue of Chromatography Today which you will find here soon (March issue).

My contribution to the issue deals with iCIEF. I have intended to provide a tutorial contribution painting the concept of iso-electrofocusing from flat gel plate to capillary formate and more recently to the instrumental implementation in imaged capillary isoelectric focusing. I hope the manuscript will interest you.

I have made it available from this website for registered visitors from here (be aware that depending on your browser settings, the document goes directly to your download folder and does not open).

It is my pleasure to announce the publication by Agilent Technologies of a 100 page guidebook on CE/MS. It is intended as a resource for novices and practitioners of CE/MS and has a focus coverpage CE MS Guidebookon the Agilent CE/MS product and applications.

It is the intention of this guidebook to help novices to step into the practical application of CE/MS, and to provide current users with relevant information on method development and on diagnosis of practical problems. Towards this goal, the booklet is divided into two parts:

Part 1: Concepts of CE/MSDescription of the concept of CE/MS coupling with detailed emphasis to help understand the technique and to choose proper starting conditions. This part is my contribution.

Part 2: Practice of CE/MS Detailed description of the practice according to recommendations of Agilent that help to set up the CE instrument, the interface, the MS, and to provide current users with relevant information on method development and on diagnosis of practical problems. Also detailed guidelines to do system performance verification will be given. This second part is contributed by Agilent specialists mentioned on page 10 of the booklet. 

Leading experts in the field of CE/MS, Dr. Julie Schappler of Geneva University and Prof. Dr. Christian Neusüß have contributed with forewords.

The booklet is highly recommend especially for those who are considering to apply CE/MS in their research. A click on the cover page will allow you to access the booklet from Agilent website.

 

32nd International Symposium on Chromatography, September 23-27, 2018

At the above symposium I have participated as the chairman of the Best Poster Award Review board and have contributed with an oral presentation.

The award presentation slides are available here.

A PDF copy of my talk is available via following link. The animation on slide 8 works but needs to be started via the button. The animation op slide 13 doesnot work.

 


On June 20, I was invited to contribute to the doctorate seminar for students participating in the Analytics for Biologics project at Groningen University, the Netherlands. Please review this link for more information on this project. See also the detailed agenda of the two-weeks seminar via the link to the agenda on this page. 

Sixteen doctorate students from Europe participated in the whole seminar and were also present during my contribution on capillary electrophoresis. 

The preparation of the CE and CE-MS course was a larger effort that I have anticipated. I was very happy to receive good help from Agilent Technologies (my former employer) especially Dr. Martin Greiner and Dr. Jens Hühner, from Dr. Julie Schappler from Geneva University, Switzerland and from Prof. Christian Neusuess from Aalen University Germany who all provided highly relevant slides. In particular I was pleased to receive 10 printed copies of the Agilent Primer on CE which has become a tool for education at many schools, colleges and universities. I am grateful to all of them.

For the students (and others) to access a PDF copy of the whole course will be through the following link. In order to access the linked menu one has to login first. Please request your account via top menu “Contact me” and login via “Registered Visitors” after you have received the account name and password.

The 1st Joint CE- and FFE Forum was held October 5 and 6, in the Fraunhofer Institute of Chemical Technology, Pfinztal (close to Karlsruhe). I had the priviledge to be the co-organizer with Dominik Mueller who is a scientist in the ICT working in the electrochemistry group. The Forum takes place annually under global responsibility and with support of the Workgroup Separation Science of the Section Analytical Chemistry of the German Chemical Society (GDCh). 

About 30 scientist, graduate and post-doctoral students attended. In principle all participants contributed with an oral or poster contribution which has stimulated intensive discussions and exchange of experience. The organizers obtained valuable suggestions for stimulation and continuation of the forum.

At the 31st International Symposium on Chromatography, I had the priviledge to arrange the reviews for the Genzo Shimadzu Best Poster Award. Together with an international board of senior peers participating in the Symposium the posters were reviewed by the following criteria:

  • Novelty and originality of the work, creativity and potential for innovation
  • Scope of work, technical quality of experimental design and execution of experiments
  • Readability of the presentation and author’s explanations (during the poster session!)

Approx. 350 posters have been submitted for presentation at ISC2016. About 150 authors have opted to participate in the best poster award competition. After  first round poster evaluation, by 16 reviewers working in pairs, 14 contributions were inivited for final round evaluation. This evaluation took place in a plenary session on Thursday, September 1 from 8:30 – 10:00 hrs, during which the nominated authors gave a flash presentation of her/his work in max. 3 to 4 slides. Fifteen reviewers in the room ranked the poster presentations and presenters which resulted in an overall rank.


It is my pleasure to announce a new monograph on CE-MS

The 42nd International Symposium on High Performance Liquid Phase Separations and Related Techniques took place in Geneva, June 21-25 2015. As at all recent HPLC symposia there was a Best Poster Award competition which was sponsored by Agilent Technologies. Also like in previous years, I had the privilege to organize the poster reviews and selection of awardees.

Of around 600 submitted posters approx. 300 authors have opted to participate in the Best Poster Award competition.  This number had to be reduced to the 10 best, who were rewarded with the Best Poster Award certificate and a cash prize of 500 Euro. 

Due to space limitations, all posters presented were divided into two groups, PSA- and PSB-series. Posters in the PSA-series were on display Monday and Tuesday; posters in the PSB-series were on display Wednesday and Thursday. There were three poster sessions every day (but for the last day Thursday). Authors were asked to be at their poster at designated sessions.


It is my pleasure to announce my involvement with Advanced Electrophoresis Solutions as a scientific advisor. 

Focused on providing cutting edge instrumentation, ampholytes and supplies, as well as superior customer support, AES recently has successfully commercialized uniques technologies and is now able to provide their customers with  CIEF (Capillary isoelectric focusing) related products such as proprietary WCID (Whole Column Imaging Detection) based high performance CIEF instruments, WCID imaging cartridges (patent pending), reference materials, electrolytes and polymer solutions. AES products are the result of the extensive dedication of scientists and engineers continuously working in the fields of liquid phase separation science electrophoresis, chromatography and analytical analysis.


September 30th I participated in the first Sciex Separations CESI-MS Users Meeting. The meeting was hosted by  Ass. Prof. Yannis Francois at Strasbourg University.  The meeting was organized by Drs. Stephen Lock and Jim Thorn of Sciex Separations.

CESI marks a novel combination of capillary electrophoresis (CE) and electrospray ionization (ESI) technologies to create an integrated workflow solution. The CE part consists of the former Beckman-Coulter PA800 CE System for Biologics Characterization and a choice of AB Sciex MS systems like the TripleTOF® 5600+ mass spectrometry system. The interface is based on the porous tip approach described by Moini (Anal. Chem. 2007, 79, 4241 - 4246) which has been extensively beta-tested by Beckman-Coulter (see e.g. Anal. Chem. 2010, 82, 9476–9483). With the formation of Sciex Separations, by combining the HPLC separation business of Eksigent with the CE separation business of Beckman Coulter, seamless complete offering for LC-MS and CE-MS is now commercially available by combining the best from Sciex MS portfolio e.g. AB Sciex TripleTOF® 5600+ mass spectrometry system.

At the 30th International Symposium  on Chromatography which took place September 14-18 in Salzburg, Austria I had the priviledge to chair a group of peers who volunteered to help select the best posters presented. Close to 600 posters were presented at the symposium of which 286 have opted to compete for the award. The Best Poster Award competition was sponsored by Genzo Shimadzu and consisted of eight 500€ grants. So it was my task to reduce the group of 286 to the eight best contributions. Banner ISC2014
