Description
The Thermo Scientific Dionex AS-AP Autosampler, Model 074925 (Manufactured 2024), serves as a reliable high-performance unit for automated sample processing in ion chromatography applications. Noted for precision and consistency, it accommodates up to 81 ten mL vials and supports simultaneous injections without cross-contamination. Featuring a polystyrene vial system for large-volume injections and all-PEEK flow paths, it's safeguarded from metal contamination and allows chemistry-switching for dual applications. Although the unit powers on, it displays errors such as EEPROM and needle obstruction, affecting full functionality verification. Original parts are available and the unit is sold AS-IS. Computer is not included.
Technician comment
Dionex AS-AP Autosampler (P/N 074925) The autosampler powers on but displays a red alarm code and fails to fully initialize. The unit will not connect within Chromeleon software and reports EEPROM and needle obstruction errors, which affect system communication. The main board, syringe drive, and XZ drive have all been replaced; however, the errors persist after replacement. As a result, full operational functionality could not be verified. Includes: Original parts replaced. Unit for sale AS/IS.
