Micro HPLC Columns

For research use only. Not for use in diagnostic procedures.

ChromXP columns optimize performance, ease of use, and reliability of the SCIEX M3 MicroLC, MicroLC 200 Plus and NanoLC 400 systems. ChromXP columns ensure optimum separation and long term stability.


  • ChromXP 300 µm, 500 µm and 1 mm i.d. columns are designed and optimized for the MicroLC Systems.
  • Achieve a high level of performance and data quality.
  • Tool-less finger-tight fittings reduce installation time and labor.
  • Column lengths from 3 to 15 cm.
  • Wide range of stationary phases including C18, C8, C4, cyano, amino, phenyl, and HALO C18, C8 and phenyl hexyl.

Designed for high-speed chromatography

Sciex microLC systems are designed for rapid, high-resolution gradient chromatography and ChromXP columns feature chemistries optimized for these high speed gradients. To achieve fast separation times, the system flow rate is proportionately2-8 times faster than conventional HPLC. These high linear velocities put added stress on the column, and stable packing is critical. SCIEX has developed a column system and packing process that ensure long-term stability, even at the extreme linear velocities that our microLC systems operate at.

Simple, tool-free column installation

ChromXP columns feature a novel end-fitting system that allows the column to be installed using fingertight fittings.

  • Superior chromatographic performance
  • Fingertight fittings for easy connections
  • Long column lifetime
  • Available in a variety of stationary phases and column lengths
