Already in 1996 Dr Maisch introduced ReproSil-Pur: this ultra pure Silica-family contains HPLC phases for reversed- and normal-phase chromatography with particles from 3 until 60 µm, with a purity higher than 99,999%. Also Turbo phases were introduced. These pure columns are packed with 1,5 µm particles and allow separations in less than 60 seconds. In addition the patented capillary guard system FixGuards, fitting to every conventional column which need no extra holder and have the advantage that they are completely free of dead volume originate from Dr Maisch.

Further innovations led to the introduction of the Silica family Stability. Stability is available with unique modifications like C30, amid-phases and BS-C23 ( 13 and 17 ). The BS-phases contain a Basic Spacer below the carbon chain and carry a permanent positive charge. Equisil® offers a cost effective alternative to the well known Hypersil HPLC phases.

Further scope of Dr Maisch includes:

  • The Reprospher line columns containing 1.8um, 2um and 2.5um particles. Also available are a range of packed Nanocolumns using fused silica tubing (50-150um i.d.)
  • Reprosil-Pur Basic and Reprosil Gold-Phases with bidentate endcapping, double bonded to the silica and therefore much more stabe than standard single bonded endcapping
  • Ultrapure Reprosil Saphir-C18 HPLC –phases with packings from 1.8 up to 10 µm
  • 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
  • Reprosil Chiral-OM (Cellulose-carbamate) and Reprosil Chiral-AM (Amylose-carbamate)
  • Cation-Exchange Columns (Reprosil-Cat) for simultaneous separation of mono- and divalent cations (Li+, Na+, NH4+, K+, Mg2+, Ca2+
