Reversed-phase C18, C8, and phenyl columns are available with a variety of particle sizes (1.7 µm to 10 µm) and column dimensions to suit UHPLC, standard HPLC, and preparative separations. All columns are packed with high-quality silica or polymer-based stationary phases with excellent lot-to-lot reproducibility. Column housings are constructed from high-grade stainless steel with end fittings compatible with standard HPLC connectors. Each column is supplied with a performance test certificate and recommended operating conditions. Suitable for pharmaceutical dissolution testing, impurity profiling, food residue analysis, environmental monitoring, and routine QC.
