Ultrasep ES Pharm-RP8EA

Endcapped C8 HPLC Column with Enhanced Alkyl Bonding

Ultrasep ES Pharm-RP8EA is a silica-based HPLC column with an enhanced alkyl-bonded C8 phase and advanced endcapping technology. This bonding chemistry provides balanced hydrophobic retention, reduced silanol interactions, and excellent stability under routine and demanding pharmaceutical conditions.

Compared to standard C8 or C18 phases, Pharm-RP8EA combines faster elution with reliable selectivity, making it ideal for the analysis of moderately hydrophobic compounds, impurity profiling, and stability-indicating assays. Its optimized endcapping ensures sharp peak shapes and reproducibility even for challenging basic analytes.

Ultrasep ES Pharm-RP8EA delivers enhanced C8 performance with advanced endcapping – the dependable choice for pharmaceutical laboratories requiring robust and reproducible HPLC separations.

Key Features:

  • Silica-based stationary phase with enhanced alkyl-bonded C8 chemistry

  • Advanced endcapping for minimized silanol interactions

  • Balanced hydrophobic retention with faster elution than C18 phases

  • High stability, reproducibility, and long column lifetime

  • Available particle size: 5 µm

Typical Applications:

  • Pharmaceutical impurity profiling and stability studies

  • Analysis of moderately hydrophobic drugs with reproducible peak shapes

  • Method development requiring complementary selectivity to C18 phases

  • Routine quality control and regulatory testing
