Dear Visitor,

On this website ROZING.COM Consulting, I have collected documents that are dealing with basics and important aspects of pressure and electrical field driven liquid phase separations.

The documents that I have prepared, have been a lot of work. Allthough much of their contents can be found in text books and publications, it has been a large task to arrange and prepare the content and make them available for your study and information. Therefore access to the menus one these pages e.g. to PDF-copies of my talks, tutorials and reports are only available after registration. When you register, I will become notified and have to approve the your account personally. Neglect the "secret code" in the registration menu.

In the content of this blog following this article, I will announce important news regarding ROZING.COM Consulting and will refer to all new content on the site. So check this blog for new information. In addition, I will mail the registered visitors occasionally.

So, if you find something interesting in the blog and/or want more information or just want to stay informed about new content added to this website. You can do this via the menu on the r.h.s. of this page. Do not bother about entering the secret code. It will not be required for your registration.

Given my previous experience regarding hacking of these pages, I hope you will understand that I am carefull and that you will appreciate my caution.

While visiting my daugther in Glasgow, Scotland, I had the opportunity to visit the Beatson Cancer Research Institute where my son-in-law hold a research position. While being there, I delivered a short tutorial on CE-MS. You will find a PDF copy of this talk here or via the menu "Publications" and menu item "My Orals". Do not forget to sign on in case you have already an account. If not, you can register on this page. You will find the login menu on the lower right side of this page. Do not bother about the "Secret Code" (it is only required for administrators).

 Dear all,

It is my particular pleasure to announce that I have received the Uwe D. Neue Award in Separation Science at the 41st International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC2014), May 11-15 in New Orleans, USA. For details about the symposium click here. This award honors a distinguished industrial scientist, preferably 15 or more years after receiving his or her doctoral degree, who has made a significant contribution to the field of separation science and continues to advance it. In addition, the awardee should be an industrial scientist, and one who was instrumental in the embodiment of technology in commercial products. The award was created in honour of the legacy of Dr. Uwe D. Neue, late scientist and Waters® Corporate Fellow and is sponsored by Waters Inc.

Dear Visitor,

I have prepared a comprehensive blog on CE-MS interfacing methods. Actually the information provided is distributed over three separate blogs viz. "CE-MS, the first steps", "The triple tube IF" and "Sheathless CE-MS IF". The first blog describes how CE-MS interfacing was developed until the HP/Agilent triple tube CE-MS interface was introduced on the market. The second blog has a few articles about the triple tube interface while the third blog describes new development and gives my assessment of the current status in CE-MS interfacing.

From January 28 -  January 31, the wellknown Hyphenation Techniques in Chromatography took place in Bruges, Belgium. Since a few years, the focus of the symposium has been expanded with Hyphenated Techniques for Sample Preparation. This were the 13th issue of HTC and the 3rd issue of HTSP. Bruges is a small town in the western part of Flanders in Belgium which is dominated by its medieval patrimonium of churches and official buildings, squares and streets. The symposium took place in Congress Centre Oud Sint-Jan which is one of those old buildings rejuvenated into a congress center. The site is very concise but allowed three parallel sessions, provided ample space for posters and an exhibition on the top level where coffee and lunch was served. Further details can be taken from the symposium website.


The 41th Symposium on High Performance Liquid Phase Separations and Related Techniques, HPLC2014, took place in the Hilton Riverside Hotel, New Orleansand from May 11-15. The symposium was attended by approx. 770 delegates. About 60-70 of these were registered as exhibitors. Accounting for invited delegates, there were about 600 paying delegates. More than 200 orals and over 450 posters were presented. Ca. 45 manufacturers exhibited besides 20 media partner. These numbers are significantly lower than at HPLC2013 in Amsterdam.

This three-part series of educational webinars on UHPLC will address and explain fundamental aspects of UHPLC to provide participants with insights and knowledge to help them make informed choices when they are preparing to apply UHPLC in the laboratory in practice. The webinar cover three core areas in three separate webinars.

The 30th International Symposium on MicroScale Bioseparations (MSB2014) took place in Pécs, Hungary, April 27 - May 1. The meeting was organized by Prof. Ferenc Kilár, who was the symposium chairman together with Profs. Attila Fellinger and András Guttman as co-chairmen under the auspices of the University of Pécs. The MSB symposium traditionally focuses on fundamental aspects of separations on the microscale or down to nanoscale. The scientific areas of the symposium cover the application of electrically driven, microscale separations for (bio)analytical  measurements  in  life  science  research,  (bio)pharmaceuticals  development,  forensics, toxicology,  doping  analyses,  food  safety  and  authenticity  and  keeping  our  environment  clean  and sustainable. See the symposium website for more information.

From October 6 - 9, 2013, the 20th International Symposium on Electro- and Liquid Phase Separation Techniques (ITP2013) took place in Puerto de la Cruz, Tenerife, Spain. The symposium series is one of the premier symposia on electrical field driven liquid phase separation techniques. Originating from a conference with premier focus on isotachophoresis (explaining the acronym) the series evolved to comprise all liquid phase electro separation techniques. Initially bi-annually, the series now takes places every other year in the Americas and Europe and has expanded it focus to encompass pressure driven liquid phase separations (HPLC).
