ISSS 2017

23rd International Symposium on Separation Science

The 23rd International Symposium on Separation Sciences (ISSS 2017), to be held in Vienna from 19-22 September 2017 will continue the series of successful conferences organized under the auspices of the Central European Group for Separation Sciences (CEGSS).

Exciting new research developments, important applications and for showcasing the most up-to-date examples of analytical instrumentation and supplies as well as analytical services in the associated company Exhibition will be presented and discussed.

Find our colleagues Till Myrach and Lilit Avagyan at booth no. A15. They will be presenting newest AZURA technology and is happy to discuss KNAUER products and solutions with you.

Moreover, visit the poster presentations that will be held by Lilit:

PO-163: Quantitative determination of gallic acid and tannic acid from gallnut extract (Wednesday, 20.9. 14:30-16:00 h)

Quercus infectoria gallae (oak gall) contain tannins which are characterized to have curative and anti-inflammatory properties. Because of their antiviral and antibacterial qualities, tannins from gallnut extracts have been used in traditional and ayurvedic medicine as well as beauty culture.
A newly developed gallnut extract was prepared in a glycerin-water-mixture. To examine the quality of this extract a reliable, innovative HPLC method was worked out to determine the containing active ingredients.

PO-58: Systematic HPLC Method Development and Robustness Evaluation of 13 Carbonyl DNPH Derivatives Using DryLab® (Thursday, 21.9. 14:30-16:00 h)

In the monitoring of industrial air, the determination of carbonyl (aldehyde and ketone) emissions is crucial to prevent respiratory, pulmonological, autoimmune diseases, and cancer. According to the analytical method described in the DIN ISO 16000-3, the carbonyls must be converted to their corresponding hydrazones with 2,4-dinitrophenylhydrazin (DNPH in order to be detected via UV detector and analyzed by reversed phase HPLC. Here, the DryLab® software was used for method optimization to separate of 13 carbonyl derivatives in a standard mixture with the AZURA® HPLC system and a DNPH-column.
