AS-AP Autosampler

The Dionex AS-AP Autosampler is designed for high precision, reliability, ruggedness, and ease of use. The AS-AP can be used with the entire ICS product family and provides high-performance, automated sample processing for ion chromatography applications.

Key Features:

  • Capable of simultaneous injection without cross contamination of chemistries
  • Consistent operation at RSDs less than 0.3% for reproducible and accurate results
  • 10 mL polystyrene sample vials with wide openings for large-volume injections and trace analysis
  • All-PEEK flow paths, compatible with aqueous and reversed-phase eluents, safe from metal contamination
  • Moving-needle design to guarantee reliable sampling from a variety of vial sizes
  • High sample capacity, up to 81 × 10 mL vials
  • Sample preparation function to automate sample and standard preparations, saving time and labor
  • Well plate capabilities, optional sample tray cooling
  • Optional in-line sample conductivity and pH measurement
  • Optional fraction collection and re-injection
  • Optional valves, one or two 6-port or 10-port valves for sequential injection, sample preparation, fraction collection, or sample injection
  • Optional Dionex AS-AP Sample Conductivity and pH Accessory that allows in-line, pre-injection measurements and can be used in conjunction with conditionals to inject, reject, or reprocess samples.
  • Chemistry-switching option to provide fully automated switching between two independent applications on the same IC system
  • Sample tray temperature control option for thermally sensitive sample that offers precise, reliable control over a temperature range of 4–60 °C


  • Free up your schedule and lab time with automated sample handling for your IC
  • Improve your results with automated sample preparation
  • Eliminate complex laboratory procedures with automated sample preconcentration

The AS-AP features are controlled through Chromeleon® Chromatography Data System software.
