Mobile Phase Cleaner

Eliminate ghost peaks. Protect columns. Stabilize baselines.

Mobile Phase Cleaner is an in-line mobile-phase cleanup cartridge packed with high-purity activated carbon beads. Installed between the pump outlet and injector inlet, it captures trace organic contaminants from solvents, reagents/additives, and upstream LC components before they reach the injector, analytical column, or detector.

Because the cleaner is positioned before the injector, the injected sample does not pass through the sorbent. This allows the mobile phase to be cleaned without directly interacting with sample analytes.

By reducing mobile-phase-derived background, Mobile Phase Cleaner improves baseline stability, increases S/N ratio, and helps enable lower LOD/LOQ in trace-level analysis. High-pressure formats up to 120 MPa make it suitable for HPLC, UHPLC, and LC-MS workflows.

Key Benefits

  • Cleaner baselines: Reduces ghost peaks and background originating from the mobile phase.
  • Higher S/N: Lowers chemical background that can obscure low-level analytes.
  • Trace analysis: Improved baseline stability supports more sensitive quantitation.
  • Column protection: Reduces contaminant loading before the injector and analytical column.
  • LC-MS ready: Designed for workflows where mobile-phase background limits sensitivity.

About Mobile Phase Cleaner

Reduction of Mobile-Phase-Derived Ghost Peaks

Blank gradient chromatograms obtained with distilled water and acetonitrile as the mobile phases. Trace mobile-phase contaminants can accumulate on the analytical column during equilibration and elute as ghost peaks as the organic strength increases. Installing Mobile Phase Cleaner upstream of the injector substantially reduced these peaks, demonstrating effective removal of mobile-phase-derived organic contaminants.

The Mobile Phase Cleaner effectively removes UV-absorbing impurities derived from mobile phases, resulting in a cleaner baseline and reduced ghost peaks.

Comparison of diclofenac sodium analysis with and without Mobile Phase Cleaner

An interfering peak observed without Mobile Phase Cleaner is effectively removed after installation, resulting in a cleaner baseline and improved analytical reliability.

HPLC Flow Path and Installation Position

Mobile Phase Cleaner is installed in-line between the pump outlet and injector inlet to remove trace organic contaminants before they enter the injector and analytical column.
