This Thermo Scientific Dionex AS-AP Autosampler (P/N 074922, manufactured April 2015) is in good cosmetic condition. The unit powers on successfully. Full functional testing was not carried out as the required Chromeleon CDS software and licence are not available; the unit is listed as working on the basis of power-on confirmation. Buyers should satisfy themselves regarding full operational status prior to purchase. Chromeleon software and licensing must be sourced separately by the buyer.

The bundle includes:
• Thermo Scientific Dionex AS-AP Autosampler (P/N 074922)
• Epson TM-U220D impact dot matrix printer with power supply/adapter
• Sample trays and carousel (installed)
• Selection of fluidic tubing, cables, and interconnects

The Thermo Scientific Dionex AS-AP Autosampler is designed to automate sample introduction, preparation, and advanced workflows for ion chromatography and HPLC systems. It supports any Thermo Scientific Dionex ICS system with simultaneous or sequential injections, and integrates with Chromeleon Chromatography Data System (CDS) software for full automation control.

Key highlights:
- Fast cycle times of less than 30 seconds for a 5 µL injection
- High sample capacity: from 81 × 10 mL vials to 1,152 positions in micro well plate format
- All-PEEK, metal-free flow paths for compatibility with aqueous and reversed-phase eluents
- Simultaneous and sequential injection to two IC systems from a single module without cross-contamination
- Supports automated internal standard addition, sample dilution, precolumn derivatisation, matrix elimination, and fraction collection
- Optional tray temperature control (4–60 °C) for thermally sensitive samples
- Fully integrated audit trails and communication feedback via Chromeleon CDS
