Kromasil HILIC-D is designed for the best selectivity of polar compounds. This diol derivatized phase provides excellent reproducibility when compared to HILIC columns based on standard bare silica. Kromasil HILIC-D offers a robust column that is 100% MS compatible. The phase is low bleed and the solvents used when running your HPLC in HILIC mode are optimal for MS. Therefore the sensitivity can be 100 times better when using Kromasil HILIC-D over traditional reversed phase columns.

Conference on Preparative & Process Scale HPLC, MCC and SFC

Beijing, China

Separation Products arranged a conference on preparative and process chromatography in Beijing, China, 27-29 October, 2010. This conference was the 6th in a series of well-attended and much appreciated chromatography conferences and workshops organized since 2002 by Separation Products. The conference was held on the outskirts of Beijing, in the Chateau Laffitte Hotel, with nice surroundings, and a hotel looking like a French castle!

About 70 people from 38 different companies and universities attended the conference, and over the three days, 17 talks and four workshops were given. The subjects ranged from drug discovery, chiral separations, and large scale application examples to equipment and packing material design, making the program useful and interesting to most everyone attending.

In addition to the scientific program an excursion to the Great Wall and the Ming Dynasty Tombs was arranged, giving all the possibility to see some of China?s biggest attractions during the visit to Beijing.

The very positive feedback from the attendees gives us courage to start already now to plan for our next conference in this series. Information on where and when will be forwarded to our friends in the prep HPLC community later on!

A Popular chromatography conference

From May 31 to June 2, Separation Products held a conference on the subject of preparative chromatography. The conference was held at Säröhus, south of Gothenburg and customers from all over the world and representatives from a variety of Universities were invited to attend and give talks.

The conference attracted guests from 27 different companies and six universities, in addition to employees from Kromasil in the US, China and Sweden. In total, 69 people took part in the event, which, despite a packed program, also gave participants the opportunity to enjoy the beautiful archipelago off the western coast of Sweden.

The conference program was intensive, with 22 talks over one and a half days. In addition to this, the group managed to take in a highly appreciated boat tour of the archipelago in fantastic weather.

We have already received praise that the conference was both educational and extremely enjoyable, it gave a lot of opportunities to make new contacts with colleagues from other companies in the same business area. So, we have already decided to arrange a similar conference in China in 2010 and another on the west coast of Sweden in 2011.

Kromasil new analytical strategy

Kromasil is a premium silica-based packing material developed for Preparative, Process and Analytical HPLC, SFC and SMB.

Kromasil analytical and preparative columns for Normal Phase, Reversed Phase and Chiral Phase liquid chromatography have been available worldwide as original columns from AkzoNobel, or via independent column packers in different countries.

In order to secure the quality and supply of our columns, Kromasil has decided to take full responsibility for all manufacturing steps from silica to column packing. From January 1st 2008, Kromasil have stopped the sales of analytical bulk material to independent column packers. Following the new analytical strategy we also establish a network of more dedicated distributors of Kromasil original columns worldwide. Kromasil original columns will only be available from AkzoNobel, or our network of distributors.
