Metrohm, 6.0103.4230, Metrosep A Supp 19 - 250/2.0

The Metrosep A Supp 19 - 250/2.0 is the high‑capacity variant of the Metrosep A Supp 19 microbore family. Building on the excellent selectivity and peak symmetry that characterize the Metrosep A Supp 19 stationary phase, this extended‑length 2 mm column provides substantially increased capacity, enabling reliable separation and quantification in highly complex sample matrices. Its narrow‑bore design ensures efficient separations with low eluent consumption, while the longer format delivers enhanced resolution for challenging analyte combinations.
Thanks to its increased capacity, the Metrosep A Supp 19 - 250/2.0 excels in applications where the 150/2.0 version reaches its limits, such as environmental samples with substantial matrix loads, industrial wastewaters, or samples containing both standard anions and organic acids across broad concentration ranges. The extended column length ensures superior separation power and reliable performance, even when confronted with heavy matrix interferences.
With inherently low flow rates, the Metrosep A Supp 19 - 250/2.0 is also particularly well suited for IC-MS coupling. The microbore format reduces background noise and enhances sensitivity in mass‑spectrometric detection, making this column a strong choice for laboratories requiring trace‑level quantification, high selectivity, and stable baselines.
