Metrosep C 4 - 250/2.0

Metrosep C 4 - 250/2.0
Beställningsnummer: 6.1050.230

The Metrosep C 4 - 250/2.0 "Microbore" cation separation column is the cation column with the greatest capacity in the C 4 series with a 2 mm inner diameter. It is predestined for applications which require high separating efficiency. Samples with extreme differences in concentrations can be analyzed reliably with this column. The performance capability of the column is demonstrated, for example, when analyzing sodium traces in addition to monoethanolamine (MEA). With the C 4 - 250/2.0, not only amines and transition metals but also alkaline and alkaline earth metals can be determined in a single run. With its low eluent flow, this column is particularly suitable for IC-MS coupling.

  • Metrosep C 4 Guard/2.0
    6.1050.600
    Metrosep C 4 Guard/2.0


    The Metrosep C 4 Guard/2.0 contains the C-4 column material and is used to protect all Metrosep cation columns with 2 mm inner diameters which have a substrate based on silica gel. Particles and contaminations are reliably retained, allowing the lifetime of the analytical separation column to be prolonged considerably. The economical price is an additional plus. The Metrosep C 4 Guard/2.0 also functions according to the "On Column Guard System" and is screwed directly onto the separation column with nearly no dead volume.
