Automatic sample preparation system XPREP-A series

Sample preparation of joint columns by analyzing AOX/TOX labor intensive and time consuming? The XPREP-A series is the fastest column sample preparation system in today’s market. Specially designed to meet international standards like ISO, EPA and DIN methods (e.g. ISO 9562, EPA 9020). It automatically runs 100 mL water samples over the AOX/TOX columns at controlled sample flow of 3mL/min. Once the water sample has passed through the columns a wash cycle automatically starts, which removes the inorganic load from the surface of the activated carbon. The surplus water and wash solution are collected in a central reservoir, which can be connected to a continuous drainage system or simply emptied when it is full. The process is fully controlled by the sample preparation system that can operate as a stand-alone unit. There are 2 basic models to choose from. The XPREP-A12 comes with 2 peristaltic pumps and the XPREP-A6 comes as a single pump configuration. The A12 version supports 12 sample containers and column positions and the A6 offers space for 6 positions. In those configurations, they run 12 or 6 paired columns in full automatic mode, simultaneously. The second column is to assure the breakthrough of sample does not exceed 10% of the total value.
