The owner Dr. Maisch has worked with HPLC for over 30 years, beginning in 1980 to isolate new insect hormones from butterflies with the, then very new technique of HPLC at the University of Ulm.
We introduced a new HPLC family, Reprospher, with 20 different phases. It is based on an ultra pure silica with the five most common trace metals all below 10ppm.
The Reprospher line is expanded to include columns containing 1.8um, 2um and 2.5um particles. We also introduced a range of packed Nanocolumns using fused silica tubing (50-150um i.d.).
We developed our very successfully Reprosil-Pur Basic and Reprosil Gold-Phases with bidentate endcapping. The endcapping is double bonded to the silica and therefore much more stabe than standard single bonded endcapping.
Introduction of the ultrapure Reprosil Saphir-C18 HPLC –phases with packings from 1.8 up to 10 µm.
-Completion of Reprosil-Pur 120 C18-AQ line, one of the most frequently used phases in the world by selfpackers of nanocolumns with 1.9 µm and 2.4 µm options.
We obtained a patent for the new trapping guard holder for nanocolumns.
-We introduced two new coated chiral phases: Reprosil Chiral-OM (Cellulose-carbamate) and Reprosil Chiral-AM (Amylose-carbamate)
-A patent was obtained for a new design of distributor plate for use in preparative columns.
Development of new preparative column hardware ( 60 – 100 mm id) with flexible piston technology (FPC-Technique).
- We developed a new prep. hardware with 200mm iD with flexible piston technology
- Development of a new Cation-Exchange Column (Reprosil-Cat) for simultaneous separation of mono- and divalent cations (Li+, Na+, NH4+, K+, Mg2+, Ca2+)
- Acquisition of Trentec company: Trentec was a German HPLC column packer and dealer of "Outstanding" columns.
- Dr. Maisch is authorized by DAISO Fine Chem GmbH, a group company of Osaka Soda Co.,Ltd., to use a trademark of "DAISOGEL" only for packed columns.
