Automated Sample Clean-Up for the PCB and Dioxin Analysis in ‘Pure’ Fractions

The DEXTech Pure automated sample preparation system offers a fast, efficient, and economic separation of analytes in two fractions using a 3-column setup with aluminium oxide.

LCTech’s latest system for sample clean-up of PCBs and dioxins, DEXTech Pure, is based on the technique of the tried and tested DEXTech Plus system, mainly used for environmental analysis applications.

DEXTech Pure separates PCBs and dioxins in one fraction each and enables the subsequent measurement of PCBs and dioxins separately in one GC-MS run each. Cross-contamination is reliably avoided.

For users measuring PCBs, the system includes a special feature in a speedy “PCB only” method: The 3rd column (carbon column) can be replaced by a dummy column and the sample only passes two columns. This saves both, solvent and costs for the already favourable columns and, above all, enormous runtime per sample. All matrices, be it food, feed, environmental, or biological samples, can be processed in an easy and efficient way.

DEXTech Pure comes with two default methods that are compliant to European and EPA methods and regulations. An individual parameterisation via touch screen is also possible with only a few taps. Up to 28 methods can be stored and reopened in the system.

The general handling of the system is just as easy as the method input. For example, the columns are simply clicked in and pressure-tight locked with an electrical mechanism, which is a contimuation of the functionality of the whole DEXTech product family. No tools or further manual working steps are required to successfully operate these instruments.

DEXTech Pure also includes important safety features such as pressure monitoring and overflow and leakage sensors.
