Feature overview
The selectivity of the Metrosep A Supp 18 columns is designed specifically for work with hydroxide eluents. The Metrosep A Supp 18 - 250/4.0 is the longer column version of the A Supp 18. High separating efficiencies are achieved with the small particle size of 3.5 µm. The symmetrical peaks enable simple determination of anions, including in low µg/L concentration ranges. In addition to the standard anions, the Metrosep A Supp 18 - 250/4.0 is particularly suitable for the separation of the halides chlorite, bro mate and chlorate at room temperature.

- Metrosep A Supp 18 Guard/4.0

- The Metrosep A Supp 18 Guard/4.0 reliably protects the Metrosep A Supp 18 analytical separation column against contamination from sample or eluent. It contains the same separation material as the Metrosep A Supp 18 IC Columns, is also made of PEEK, and is screwed directly onto the respective separating column with virtually no dead volume ("On Column Guard System"). The guard column prolongs the service life of the analytical column, without influencing chromatographic separating efficiency.
