Pre-Packed Columns

Our columns offer flexible options to meet your specific needs, allowing you to tailor the inner diameter (i.d.), length, and emitter options to achieve your desired balance of sensitivity, throughput, and resolution. You can choose between integrated or non-integrated emitters, as well as options with or without fittings, providing full compatibility with your system setup.

Sensitivity, Throughput, and Resolution

Sensitivity

• Super High Sensitivity: Smaller i.d. (e.g., 30 µm), ideal for detecting low-abundance species.
• Higher Sensitivity: Moderate i.d. (e.g., 50 µm), balancing sensitivity and throughput.
• Moderate Sensitivity: Larger i.d. (e.g., 75 µm) for general applications.
• Low Sensitivity: Larger columns (e.g., 150 µm) prioritize throughput over sensitivity.

Throughput

• Super High Throughput: Shorter columns and larger i.d. for faster analyses.
• Higher Throughput: Moderate i.d. and length for slightly slower separations but higher sample load.
• Moderate Throughput: Longer columns and moderate i.d. for balanced performance.
• Low Throughput: Longer columns, especially with smaller i.d., for superior resolution but slower analysis.

Resolution

• Super High Resolution: Longer columns and smaller i.d. (e.g., 75 µm × 25 cm) for precise, detailed separations.
• Higher Resolution: Moderate-length columns (e.g., 75 µm × 15 cm) offering great resolution without sacrificing too much speed.
• Moderate Resolution: Balanced, achieved with shorter columns or larger i.d. for faster analysis.
• Low Resolution: Larger i.d. columns with shorter lengths, prioritizing speed over fine separation.
