Overview of the Astoria-Pacific 311 Sampler

The 311 XYZ Sampler is a core component of Astoria‑Pacific's modular segmented flow analysis systems, such as the Astoria and Astoria2 analysers:

Functionality

It acts as a random-access sample introduction system in an XYZ grid format, enabling automated handling of samples in liquid analysis workflows

Integration & Automation

It is typically integrated with detectors, peristaltic pumps, and cartridge bases to form a complete automated analyzer capable of walk‑away operation and high throughput, with assay results available within 15–20 minutes upon sample loading

Throughput & Sensitivity

When paired with the Astoria Analyzer, systems using the 311 sampler can process between 90 to 120 samples per hour, delivering part-per-billion detection capabilities along with efficient reagent usage (up to 10× lower compared to traditional SFA systems)

System Flexibility

The 311 sampler offers flexibility and ease of use, allowing automatic insertion of check calibrants and compatibility across different system configurations (e.g., Astoria2, SFA3000)

Support Modules

For optimal performance, it can be paired with auxiliary modules such as the 322 Auxiliary Pump, which serves as a dedicated wash pump for the samplerD 303 305D Autosampler +
