High Throughput Combined with Advanced Sample Preservation – Reliable Assurance for Long Analytical Sequences

The 96‑position water/soil integrated autosampler operates fully automatically, enabling round‑the‑clock unattended operation to meet the demands of high‑throughput sample testing. An optional sample tray refrigeration feature ensures that VOC samples remain stable during extended waiting periods prior to analysis. The split‑type sample tray design offers a more user‑friendly approach to sample loading.

3rd‑Generation AFC Pneumatic Control System – World‑Class Precision
The independently developed third‑generation AFC pneumatic control system delivers a control accuracy of 0.001 Psi, achieving performance on par with leading international standards.

Inert Flow Path, Intelligent Water Removal, and High‑Efficiency Trapping
The fully inert flow path design, combined with support for hot water and methanol rinsing, effectively minimizes system carryover and ensures low detection limits. The high‑performance U‑shaped trap system captures VOCs while minimizing water and methanol adsorption. Equipped with a high‑efficiency helical water removal system, it effectively reduces the impact of water on GC/GC‑MS performance.
An automated internal standard addition function simplifies operation, improves analytical efficiency, and enhances sampling accuracy and reproducibility. A magnetic stirring function is provided as standard, effectively increasing purge efficiency for soil samples.

Excellent Repeatability, Ultra‑Low Carryover, and Precise Linearity
The system delivers outstanding repeatability, ultra‑low carryover, and highly linear calibration curves, ensuring reliable quantitative results across a wide concentration range.
