Answer:It contains 3.5 µm C18-bonded silica particles in a 4.6 × 150 mm analytical format.
Answer:The stationary phase has nominal 100 Å pores and approximately 14% carbon loading.
Answer:This GL Sciences variant has a maximum operating pressure of 20 MPa, equivalent to 200 bar.
The GL Sciences InertSustain C18 analytical column uses highly purified silica with densely endcapped octadecyl groups to reduce undesirable adsorption during reversed-phase chromatography. Its 3.5 µm particle size and 4.6 × 150 mm dimensions balance conventional HPLC resolution with practical operating backpressure. The stationary phase has a nominal 100 Å pore diameter and 14% carbon loading, providing hydrophobic retention for a broad range of organic analytes. Low residual silanol activity can help improve peak symmetry for compounds that interact with active surfaces. The column is designed for mobile phases within pH 1 to 10 and has a specified maximum pressure of 20 MPa, or 200 bar. Set the instrument flow and solvent composition within this limit and monitor system pressure during use. Filter samples containing particles and avoid introducing poorly dissolved material. Establish reproducible equilibration and wash conditions when working with sample matrices that contain proteins, salts or strongly retained contaminants.
