Archon
Purge & Trap Autosampler
VOC-orginal
Productivity in environmental laboratories is improved with the Archon Purge and Trap AutoSampler. The Archon features combine to provide the ultimate solution for water and soil VOC analyses (EPA 500/600 and EPA 8000 series methods).
Hot Water Rinse System
The entire sample pathway including the sparge vessel are automatically rinsed with 90°C blank water followed by a programmable helium flush. Carryover is minimized giving you increased confidence in your analytical results. Plus, faster cycle times improve productivity.
Higher boiling analytes are easily handled with Archon’s high temperature (up to 250°C) valves and transfer lines.
Large Sample Capacity
The removable 51 position sample tray accepts water or soil samples in any order for random analysis. Archon’s small footprint saves precious benchspace. Store up to thirty methods for maximum flexibility.
Designed For Safety
Archon’s low profile engineering and see-through safety cover protects operators from hot surfaces, the robotics arm, gripper, and pinch points.
Additional protection is provided by an interlock which stops the robotics motion when the Safety Shield is opened.
Mode of Operation
Prior to transferring water samples to the sparge vessel, programmable amounts of internal and matrix spike standards may be added from either of two reservoirs, saving time and improving analytical precision. In addition, water samples may be automatically diluted up to 100 times.
Following the purge cycle, sample pathways are flushed with helium, rinsed with hot water, and flushed with helium once more. The number of flush and rinse cycles after each sample is programmable up to 20 times.
Solid samples, such as soil, contained within either standard SoilVials or needle sparge vessels are placed directly into the sample tray. After programmable amounts of diluents water and standards are added, Archon mechanically stirs and heats the sample up to 125°C to maximize analyte recovery. Purging of analytes is done directly from the vial, and afterwards, the sample pathway is cleaned with a high flow of helium.
