HPLC Column Polaris, C18-A, 180Å, 5 µm, 4.6 x 200 mm

Polaris HPLC column with inner diameter 4.6 mm, length 200 mm and particle size 5.0 µm. Polaris HPLC columns offer a variety of polar phase chemistries that reliably separate mixtures of polar and non-polar analytes with excellent peak shapes.

Polaris C18-A is designed for high-throughput and LC/MS analysis of polar compounds in research and development, especially for new drug discovery, drug metabolism, etc. The functional groups of Polaris C18-A are combined with polar groups located near the silica surface. These polar groups have two functions: First, they improve the retention mechanism of polar substances. Second, the polar groups 'deactivate' the few remaining silanols by charge displacement, thereby improving the peak shape.
