Metrohm, 6.0103.4220, Metrosep A Supp 19 - 150/2.0

The Metrosep A Supp 19 - 150/2.0 combines the outstanding separation performance of the Metrosep A Supp 19 stationary phase with the efficiency advantages of a 2 mm microbore format. It delivers excellent selectivity, sharp peak shapes, and high capacity, enabling precise quantification of both standard anions and organic acids, even in demanding sample matrices. Owing to its reduced eluent consumption and inherently low flow rates, the 150/2.0 version is particularly well suited for IC–MS coupling, offering enhanced sensitivity and reduced background noise in mass‑spectrometric detection.
Built on the proven mechanical, thermal, and chemical stability of the Metrosep A Supp 19 packing material, this column maintains outstanding robustness even at elevated pressures and varying eluent conditions. Its narrow‑bore design ensures highly efficient separations, while still providing the high anion‑exchange capacity required for accurate analyses across a wide concentration range.
In addition to its suitability for classical water and environmental analysis, the Metrosep A Supp 19 - 150/2.0 is an excellent choice for air‑monitoring applications, including fully automated systems such as MARGA (Monitor for Aerosols and Gases in Ambient Air) and MARS (Metrohm AeRosol Sampler). The combination of high separation efficiency, low flow requirements, and stable baseline performance makes this column ideal for continuous, high‑precision monitoring of atmospheric anions.
