AOX Sampler Series The Easiest POX, EOX, TOX Determination

Autoinjector AI

Intelligent constant rate syringe drive for the safe, semi-automatic injection of liquid samples in the vertical operation mode. Thanks to one-step filling it is possible to reach dosing precision of an autosampler, independant of the operator. The autoinjector is equipped with a 100 µl syringe to enable best results, even for analysis in the trace range. The integrated sensors automatically check for proper filling of the syringe, thus eliminates main sources of operation mistakes. The autoinjector is the ideal solution for small sample numbers resp. in case EOX analysis is seldom done.

• Automatic recognition of syringe and correct filling – elimination of user mistakes
• Software controlled, constat injection rates for controlled, complete combustion
• Easy software-guided operation
• Resource saving – no additional power supply, extremely light and small design

ABD – Automatic Boat Drive

The ABD enables AOX acc. column and batch methode as well as EOX and TOX analysis in the horizontal operation mode. Therefor the samples are introduced either manually or automatically, by aid of the autoX112 autosampler, into quartz sample boats. The ABD transfers the loaded quartz sample boats fully automated into the combustion furnace. The process can be adapted to the specific needs of samples resp. user preferences by flexible programming of up to 3 waiting positions and adaptation of transfer speed, if required. The optional available flame sensor enables a safe and optimized combustion process of any organic matrix, independant if solid or liquid. The ABD enables automated supply of AOX columns and enriched charcoal together with polycarbonate membrane filters (batch method), solid samples up to 110 mg, up to 100 μL EOX extracts or other organic liquids. The flame sensor is required in case of analysis of pure organic as well as vigorously reacting sample matrices (e.g. EOX extracts, polymer waste, used oil etc.).

• Cooled sample port – enables analysis of EOX extracts and other light volatile liquids
• High-performance Peltier cooling for sample boats – minimum idletime in liquids applications
• Automatic port opening and pressure sensors – high operation safety, maximum operation comfort in solids & AOX applications
• Optional flame sensor technology – Intelligent fully automatic adaptation of the combustion process to the specific needs of any matrix component - remarkably reduced downtime and maintenance effort, quantitative digestion even for huge quantities, very reactive samples or unknown matrices
• Safe and easy operation – very suited for shift work and analysis of unknown samples
• Free choice of ABD operation mode allows time and matrix optimized analysis with streamlined throughput
• Minimum maintenance – AOX column and ash is easily removed together with the sample boat manually resp. fully automatically if autoX112 is used.

POX Module

The POX module is an optional accessory for multi X 2500 systems. It enables the determination of POX – purgeable organic halogen compounds – in wastewater and sludge samples. The samples are purged out automatically, a water bath is used to support this process.
