Fully Automated AOX/TOX Column Preparation and Introduction

TE Instruments (the Netherlands) presents the TUSCAN, an AOX/TOX column auto sampler with 42 positions.  Combining the column auto sampler with the XPREP-A series results in an exceptional high-throughput system. Due to fully automated column preparation and introduction, the analysis runs practically unattended.

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 complete process is fully controlled by TEIS Software.

Running the analysis, practically unattended, has become the new  reality. Up to 42 columns can be loaded into the TUSCAN column auto sampler. A full run will take approximately 6-7 hours. While the XPLORER is analysing, fresh columns can be prepared with the XPREP-A6 again. This takes only 45 minutes for 12 columns, and provides the user enough time to refill the column auto sampler before the next run.

For high demanding laboratories, TE Instruments offer the XPREP-A12. With the XPREP-A12 a laboratory can double its sample pre-treatment capacity allowing an even higher sample throughput. This column pre-treatment system is capable of producing enough columns to feed two combustion analysers full throttle on a 24/7 basis.
