ProntoSIL C1 is a C1-bonded stationary phase that offers the lowest sample retention within the entire ProntoSIL product range. It is primarily used for the separation of non-polar substances and can also be utilized for protein separation under Hydrophobic Interaction Chromatography (HIC) mode. Thanks to Bischoff's unique bonding technology, ProntoSIL C1 maintains excellent stability even in environments with pH levels as low as 1.
