Metrosep C 4 - 100/2.0

Metrosep C 4 - 100/2.0
Order number: 6.1050.210

The short version of the Metrosep C 4 "Microbore" cation separation column with a 2 mm inner diameter is intended for rapid determinations of the standard cations. Very short retention times are achieved; however the elution times of sodium and ammonium still differ by 25 s. When a special eluent is used, the six cations lithium, ammonium, sodium, calcium, magnesium and potassium can be determined in less than 5 minutes with the Metrosep C 4 - 100/2.0. With its low eluent flow, this column is particularly suitable for IC-MS coupling.
