DEXTech Pure: Solid Standard Solution in Dioxin Analysis

The sample is loaded quantitatively into the system via this needle. The sample container is rinsed several times (quantitative transfer). During the rinsing processes, the needle is also cleaned inside and out to prevent contamination.

The sample loop is used to focus the sample onto the silica column at the same time as the cleaning solution of the automated sample transfer. It is continuously flushed with fresh reagent and thus remains demonstrably contamination-free. By using a sample loop, the sample does not come into contact with either the syringe pump or the piston pump, allowing the system to be cleaned quickly.

This is how the system loads a sample:

The columns are clipped into the column tower in a few seconds. After pressing the start button, they are pressed together pressure-tight and the process is started. For your protection, the columns can only be pressed together when the door is closed. You can find the matching clean-up columns here.

Convince yourself of the easy handling in the following videos.

The syringe pump is used to load the sample onto the column. The sample does not come into contact with the pump, so that it always remains contamination-free.

All tubing connections are permanently installed and do not need to be conditioned or changed for each sample.

Via the touch display the user is guided through an intuitive operating program to start recommended and tested default methods for different approaches (e.g. dioxins and PCB or PCB only etc.) around methods stored in the system. Method development by the user is not required, yet programming of own methods remains possible.
