The Solution for Purified Fractions
DEXTech Pure offers the unique clean-up of PCBs and dioxins in one “pure” fraction each. This is the perfect solution for customers interested especially in measuring PCBs and dioxins separately within one GC-MS run each or also for customers interested only in PCB analysis, as it is often relevant in the environmental sector. In this case DEXTech Pure offers a 2-column-method reducing the run time.
DEXTech Pure looks the same as DEXTech Plus, but is modified in terms of fluidics and methods.
DEXTech Pure thus enables the fully separation of PCBs and dioxins based on aluminium oxide. Besides this new method, the conventional clean-up method, as it is established on DEXTech Plus already on aluminium oxide column in its fast and economic method, can also be used.
3-Column Set-up with Patented Locking System
The DEXTech Pure system is designed with a 3-column set-up, like DEXTech Plus. Depending on the individual requirements, matrix or desired method, the user can load the DEXTech Pure with different set-ups, simply insert the respective columns - "just click it". No screw connections, no tools, no other manual steps.
From sample to sample - fast, flexible, effortless.
- Acidic silica gel column: depending on the sample SMART column (samples of up to 1,5 g fat) or Universal column (sample of up to 5 g fat)
Easy and fast change between Universal and SMART-columns by fitting an adapter.
- Aluminium oxide column
- Carbon column: reusable
Advantage: Cost saving for "pure" PCB analysis, because the carbon column is not needed and replaced by a dummy column.
DEXTech Pure is delivered with eight evaluated standard methods stored in the system, which allow the user to start with the real sample processing immediately after installation of the instrument. No method development is necessary. The following methods are available for use with both the Universal Column and the SMART Column.
Besides the standard methods, you have the freedom to configure the DEXTech Pure system according to your requirements adapted for each sample. The user can freely parameterise a method and save it in the system. Up to 30 methods can be opened and modified at any time and then be saved again under a different name.
DEXTech Pure: Sample Preparation Done by Specialists
DEXTech Pure provides the established benefits of DEXTech Plus like easy handling, automated sample loading, a wide variety of safety features and good results, already proven by numerous private and governmental institutes.
Due to exchangeable columns, permanent rinsing of all parts, which were in contact with the sample, and the fact, that sample and syringe pump have no contact, cross contamination is reliably excluded.
