The CENTURION is a flexible purge and trap autosampler available in two configurations: a combined water/soil system or a water-only system. Purge and trap technology enables the extraction of volatile organic compounds (VOCs) from samples by purging them with an inert gas onto a sorbent trap, where they are concentrated and subsequently transferred into instruments such as GC or GC/MS for precise analysis.
Designed for laboratories worldwide, the CENTURION enhances throughput, ensures reliable performance, and simplifies VOC sample preparation. With robust engineering and intuitive software, it helps analysts and technicians maximize efficiency and maintain consistent results across demanding workflows.
