MZ-Gel SDplus
MZ-Gel SDplus is a highly cross linked poly(styrene-divinylbezene)-copolymer from MZ-Analysentechnik GmbH especially designed for organic eluents. It is available with porosities from 100 Å to 1,000,000 Å and linear according to a molecular weight range up to 10 million D.
Typically, our columns are packed, tested and shipped in THF (other specifications on request). Please consult the graphics below for changing the eluent or order your free printed copy via e-mail.
Below you also find graphics illustrating the long-term-stability and linearity of our columns.
Langzeitstabilität und Reproduzierbarkeit: MZ-Gel SDplus - neu und nach >1.000 Injektionen.
MZ-Gel SDplus consists of a cross-linked copolymer styrene divinylbenzene with a very narrow pore and particle size distribution. Our GPC columns are offered in 7 porosities and linear as new and in a refill. The typical number of trays for the material MZ-Gel SDplus 3 µm is> 100,000 plates /m. The 5 µm material also has a high degree of selectivity and typically reaches 80,000 - 100,000 theoretical plates /m.

MZ-Gel SDplus GPC columns are manufactured, tested and shipped in THF as standard. Of course, they are also available in other common solvents on request. When changing the solvent, the swelling behaviour must be taken into account.
GPC solvents can be divided into four groups from very strong to weak according to their swelling behaviour. This results in the following conversion options:
