德國Bischoff 
總部座落于萊茵河畔風光秀麗的小城萊昂博格的Bischoff色譜技術責任公司（德語名：Bischoff Analysentechnik und –ger?te GmbH），自1980年Klaus Bischoff博士接手后，給這家原本只是提供液相色柱再填充業務的小公司帶來了不斷擴大的產品線和全新的運作理念譜，使其在上世紀最后20年中取得了飛速發展，一躍成為歐共體最大的液相色譜柱生產商，產品范圍也從單一的色譜柱發展為液相色譜分析儀，各類檢測器和色譜配件等。產品遍及歐洲各大科研機構和高校，在歐共體發表的一半以上的有關液相色譜分析的論文都采用了Bischoff的色譜柱產品。

BISCHOFF Chromatography was founded in 1980 by Klaus Bischoff as a company specializing in refilling used HPLC columns (Refill Service). Since 1980 the company's philosophy has been greatly influenced by Klaus Bischoff′s experience. This includes working for a well-known HPLC manufacturer for many years, working in the domains of development, application, quality control and distribution as well as his close contacts to renowned university professors in Germany and other countries. Our company is committed to the use of modern technology in order to supply high quality and long life products that are application and user oriented while reducing cost and producing reliable results at the same time. The employees of this innovative, high tech company feel a strong obligation to conserve resources, work environmentally-friendly and reduce waste and pollution dramatically by optimizing separation techniques and miniaturizing instruments. These are some of the reasons why our world-wide unique Refill Service was readily accepted by customers. BISCHOFF Chromatography developed the universal HYPERCHROME column system as early as 1981 to standardize column hardware. This unique system makes it possible to use the HYPERCHROME column as a cartridge or a conventional column. We offer almost the whole range of commercially available packing materials prepacked in HYPERCHROME hardware. With our reliable technique, quality and performance it did not take long for BISCHOFF Chromatography to become one of the leading column manufacturers in Germany and Europe.

In addition to developing instruments and improving the HPLC methods currently used, BISCHOFF Chromatography has continued to develop new stationary phases or transformed existing phases into marketable products. This has been accomplished in collaboration with universities and other research institutes. Intense research and long standing experience with commercially available silica gels have led us to our new, ultra pure silica gel ProntoSIL. ProntoSIL is the basis of our top quality stationary phases. These phases and our proven packing technology are used to manufacture high performance columns, setting a new standard in the world of HPLC.

On behalf of the whole staff of BISCHOFF Chromatography I would like to assure you of the following:

It is our aim to provide the best high performance columns to HPLC users around the world. We measure the quality of our service in the nature of our technical support and after-sales service and not only in the product itself. It is our desire to assure customers' satisfaction and make an important contribution to the future of life sciences and all other chemical industries.
