The Thermo Scientific Dionex AS-AP Autosampler is an automated sample-injection and sample-preparation system designed for use with Dionex Ion Chromatography (IC) systems. The instrument shown in the photograph is clearly identified on the front panel as Dionex AS-AP and features the characteristic automated moving-needle sample-handling assembly, sample tray, injection mechanism, and enclosed drive system.

The AS-AP is designed to automate routine sample injection as well as advanced sample-preparation workflows. Thermo Fisher Scientific specifies compatibility with Thermo Scientific Dionex ICS ion chromatography systems and supports both simultaneous and sequential injections. The system can also perform automated dilution, resampling, fraction collection/re-injection, internal-standard addition, and precolumn derivatization depending on the configuration.

The AS-AP uses an all-PEEK sample flow path and a moving-needle design capable of handling different vial and well-plate formats. Published specifications provide sample capacities of up to 81 × 10 mL vials, 120 × 1.5 mL vials, 120 × 0.3 mL vials, three 96-well plates, or three 384-well plates.

The photographed unit appears to be in used condition, with the internal sample-handling area visible. The exact tray configuration, cooling option, accessories, tubing, syringe, injection valve, and software configuration should be verified before purchase.

Applications

The Dionex AS-AP is primarily used for automated sample injection in ion chromatography laboratories. It can be integrated with compatible Dionex IC systems to improve sample throughput and reduce manual injection steps. Its automated sampling mechanism is suitable for routine analytical workflows where consistent and repeatable sample handling is required.

The autosampler can also support more advanced IC workflows, including automated dilution, matrix elimination, sample preconcentration, internal-standard addition, precolumn derivatization, fraction collection, and re-injection. With its large sample capacity, it is suitable for environmental, pharmaceutical, food and beverage, chemical, water-quality, and research laboratories.

Benefits of Refurbished Laboratory Equipment

Purchasing a refurbished Thermo Scientific Dionex AS-AP Autosampler can provide laboratories with an economical way to automate sample injection on compatible Dionex ion chromatography systems. Automated sample handling can improve consistency between injections while reducing repetitive manual laboratory work.

The AS-AP is particularly useful for laboratories processing large numbers of samples because of its high vial and microplate capacity. Its automated dilution, resampling, and other sample-preparation functions can also help streamline more complex IC workflows. Compatibility with Chromeleon CDS provides integration with automated chromatography methods and instrument control.

Additional Information

The photographed instrument is identified as a Thermo Scientific Dionex AS-AP Autosampler. The photograph shows the main autosampler enclosure, sample tray area, moving injection assembly, and associated internal mechanisms. The exact tray arrangement, syringe, sample vials, tubing, injection components, temperature-control option, communication cables, and other accessories are not fully confirmed from the photograph.

The AS-AP should be matched with a compatible Dionex IC system and appropriate Chromeleon configuration before installation. The condition of the sample needle, syringe, injection valve, drive mechanism, tray movement, tubing, sensors, communication interface, and optional temperature-control system should be verified before operation.
