ACME

ACME

ACME HPLC/UHPLC columns are based on a new 120 Å ultra-high purity (99.999%) extra-treated porous spherical silica with a narrow particle size distribution and an extremely low metal content(< 10 ppm) to minimize silanol acidity and reduce surface metal sites available for chelation. ACME PLUS HPLC/UHPLC are based on the same ultra-high purity silica with a pore size of 200 Å.

Combined with a proprietary bonding technology this results in columns with optimal efficiency, asymmetry, and minimal back pressure. ACME silica pore structure shows dramatically improved performance on real samples.

ACME

 

  • Ultrapure porous silica particles enable high peak efficiency across all particle sizes.
  • 1.9, 3, 5 µm particle sizes for simple method transfer between HPLC & UHPLC.
  • Column hardware compatible with HPLC and UHPLC.
  • Consistent and reproducible retention times allowing direct scale-up from the laboratory through process applications.
