A wide portfolio of matrix-, application-, and throughput-optimized sample preparation systems allow for maximum throughput at minimum operation effort. Benefit from reduced idle times, robust hardware, and minimum maintenance requirements.

APU 28 series – Smart AOX and AOF sample preparation according to column method

APU 28 connect combines usability and speed in AOX and AOF sample preparation. The touch display offers intuitive operation with minimal effort and reduced programming time for any skill level. Parallel sample enrichment allows you to reduce the preparation time in your lab significantly. The highly durable components guarantee a long service life and enable 24/7 operation.

• Fast: Automatic enrichment of up to 28 samples
• Smart: Intuitive operation via touch display
• Flexible: Wide range of applications – SPE-AOX, AOX and AOF column method

The SPE option is ideal for saline samples. It enables AOX, AOF and SPE sample preparation with one device, significantly simplifying your routine analysis. All APU 28 connect systems can be used with AOX/AOF adsorption columns of other manufacturers. A flexible tray and optimized column holders enable fast and easy processing.

APU sim – Ideal for small sample series

APU sim offers the simultaneous and fast enrichment of up to six AOX or AOF samples using the column method, or semi-automated processing of SPE samples, or preparation of up to 6 water samples for EOF analysis. Designed with three enrichment channels, each channel can be operated and started individually. Sample volume, wash volume, and flow rate are adjusted individually and variably. The system stands out with excellentparticle handling thanks to the large diameters of the hoses and the absence of conventional valve technology.

• Wide application range – AOX and AOF column method, SPE-AOX or EOF
• Cost-effective solution for small sample series
• High throughput speed – up to 6 samples prepared simultaneously
• Suitable for particle-containing and saline samples
• Column flexibility – utilization of versatile AOX and AOF column brands and sizes

AFU 3 – The versatile all-rounder

The system allows for semi-automated sample preparation of up to three samples according to batch and column method. It’s an effective alternative to classical membrane filtration as using expensive polycarbonate filters is not necessary. Filtration is done directly into a frit container. The system can be extended easily for semi-automated preparation of up to three samples according to column method.

• AOX sample preparation according to batch and column method
• Semi-automated enrichment of up to three samples simultaneously
• Attractive alternative to classic membrane filtration (batch)
• Easy operation, fast processing without sample loss – pressure-supported filtration (batch)
• High operational safety – pressure proof sample vessels and protective front cover
