Stability 120 BS-C23 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a stable-bond C23 bonded phase. The extra-long alkyl chain provides very strong hydrophobic retention and unique selectivity compared to conventional C18 phases, making it particularly suited for highly hydrophobic analytes and complex mixtures.
The stable-bond technology ensures exceptional chemical robustness under extreme pH conditions, aggressive mobile phases, and elevated temperatures, guaranteeing long column lifetime and reproducible performance in challenging analytical environments.
Stability 120 BS-C23 columns from Dr. Maisch HPLC GmbH deliver maximum hydrophobic retention and outstanding stability – the reliable choice for long-lasting, high-performance HPLC separations.
