There have been existing columns for directly analyzing drugs in serum, each with the following drawbacks: 1. Pre-treatment columns for column switching complicate LC system configuration. 2. Isocratic analysis columns constrained by organic solvent concentration. 3. LC-MS incompatible columns requiring phosphate buffer in the mobile phase.

Cadenza HS-C18 is the world's first hydrophilic/hydrophobic hybrid ODS column capable of direct serum injection. It excludes high molecular weight serum proteins like albumin from the packing pores, while hydrophobically retaining low molecular weight drugs within the pores and separating them by organic solvent gradient elution.

Simplifying serum pretreatment processes, it is anticipated to be applied in the field of Therapeutic Drug Monitoring (TDM) where rapid analysis is crucial. Recently, it has been widely used to control surfactant concentrations, stabilizers of monoclonal antibody formulations in high demand. Additionally, this product effectively separates hydrophilic polymers other than proteins and drugs in liquid formulations such as injectables.

Cadenza HS-C18 enables LC-MS analysis of small molecules in protein and hydrophilic polymer solutions, expected to be widely adopted in various fields including blood analysis and formulation analysis.
