CDS Analytical 8500A Autosampler

High‑Capacity Sample Handling

With 110 sample positions, the 8500A supports large batch runs and continuous unattended operation, making it ideal for environmental labs, municipal water facilities, and high‑volume testing environments.

Flexible Sampling Volumes

The system supports 0.1 mL to 25 mL sampling volumes, allowing precise control for trace‑level analysis, calibration curves, and variable‑volume workflows.

4‑Channel Internal Standard Capability

A built‑in 4‑channel internal standard system (1/2/5/10/20/25 μL) ensures accurate quantitation and reproducibility across large sample sets.

Designed for Water & Soil Analysis

The 8500A includes dedicated modes for:

• Water samples
• Soil extracts

With soil heating up to 150°C and an adjustable magnetic stirrer, the system ensures complete homogenization and consistent sampling.

Precision Placement & Reliable Operation

With 1 mm 3D placement accuracy, the autosampler ensures consistent needle positioning, reducing carryover and improving reproducibility.
