Dionex AS-AP Automatic Sampler - Fair Condition

Dionex AS-AP Thermo Fisher Scientific: Automation and performance for your analyses

The Dionex AS-AP is an automatic sampler that provides a complete automation solution for ion chromatography. Designed to integrate seamlessly with Thermo Scientific chromatography systems, it automates complex sample preparation processes while ensuring exceptional accuracy and reproducibility. Thanks to its modular design, it can be easily adapted to different applications, from routine analyses to more specialised methods.

Its simultaneous and sequential injection capability significantly increases analysis throughput by allowing a single module to be used for two separate systems. This feature saves time and optimises the use of laboratory resources, thereby reducing operating costs.

The Dionex AS-AP's compatibility with a wide range of sample containers – from 10 mL vials to 0.10 mL well plates – offers great flexibility to meet the specific needs of each analytical method. Features such as automatic dilution, internal standard addition and pre-column derivatisation facilitate the implementation of complex methods and reduce human intervention, thereby limiting the risk of errors.

The temperature-controlled environment, ranging from 4 to 60°C, ensures optimal preservation of sensitive samples, including amino acids, proteins, peptides and other thermolabile compounds. In addition, its PEEK needle and circuit system ensures full compatibility with corrosive or metal-sensitive samples and buffers, eliminating potential contamination issues.

For even greater automation, the sampler is equipped with unique features such as online measurement of sample conductivity and pH prior to injection. These measurements, combined with Chromeleon CDS software, enable automatic actions such as injection, dilution or sample modification.

The Dionex AS-AP also stands out for its reliability. Equipped with an integrated communication system with audit trail, it ensures rigorous monitoring of operations and offers the possibility of automatically restarting sample analysis if an out-of-range concentration is detected. This intelligent approach optimises analysis time and delivers actionable results without additional manual intervention.

Designed to meet the needs of modern laboratories, the Dionex AS-AP is an essential partner for improving the quality and efficiency of analyses while offering unrivalled flexibility.
