Accucore XL


Based on Core Enhanced Technology using 4um solid core particles, Accucore XL HPLC columns allow users of conventional HPLC methods to enjoy performance beyond that of columns packed with 5µm, 4µm or even 3µm fully porous particles. Very high separation efficiencies using standard HPLC instruments and conditions provide increased peak resolution and lower limits of detection.

  • 4µm solid core particles
  • Robust, fast and easy to use
  • Compatible with conventional HPLC methods
  • Long column lifetime
  • Moderate back pressures

Accucore XL HPLC columns generate higher efficiencies than columns packed with 5µm and 3µm fully porous material.

Back pressure:

Accucore XL HPLC columns generate reasonable back pressures, moderately higher than fully porous 5µm and lower than fully porous 3µm, that are compatible with conventional HPLC instruments. 


The high chromatographic efficiencies offered by Accucore XL HPLC columns lead to lower limits of detection.


In addition to using established methods, the high efficiencies offered by Accucore XL HPLC columns, across a wide range of flow rates, allow methods to be optimised to reduce run times and increase productivity.
