ProntoSIL C18 AQ

ProntoSIL C18 AQ with its unique bonding technology has been especially developed for the use in aqueous mobile phases with an organic content below 10%. Standard stationary phases with conventional bondings give very poor peak shapes under these chromatographic conditions due to the collapse of C18-brushes in aqueous eluents. ProntoSIL C18 AQ gives excellent peak shapes in these mobile phases resulting in enhanced selectivities. The advantages of the AQ-packings can be demonstrated in applications of polar analytes. The C18 AQ-bonding type is fully endcapped and available in several particle sizes and pore sizes of 120 Å and 200 Å.
