AOX, AOF and EOF Sample Preparation Series Take the Fast Lane to Success
- AOX enrichment acc. column method (e.g. ISO 9562)
- AOF enrichment acc. column method (DIN 38409-59)
- Preparation of water samples for EOF determination
- Robust hardware – minimum maintenance and downtime
- Application flexibility – easy adaptation to other AOX, AOF (CIC) and fluorine analyzers (HR-CS-MAS, contrAA) for PFAS sum parameter determination
- Easy operation
Our systems help to minimize unproductive downtime and preparation effort, while increasing your throughput of AOX, AOF and EOF samples and thereby remaining flexible and cost-effective.
The smart way of AOX, AOF and EOF sample preparation
Sample preparation is the bottleneck in AOX, AOF and EOF analysis. There are numerous obstacles that can distort analysis results. Standard-compliant sample preparation is therefore essential to ensure reliable analyses and a time-saving, easy-to-use workflow. Get to know our harmonized concepts of sample preparation and analysis and benefit from the efficiency and versatility our systems offer.
- Optimum adaptation to your application and throughput demands – semi-automated up to fully-automated workflows
- Unique efficiency by harmonized sample preparation and combustion systems – allows for up to 112 samples per day
- Maximized efficiency – preparation of up to 6 samples simultaneously
- Standard-compliant operation
- Application versatility – EOF, AOX-SPE, AOF, AOX batch and column method, one, two and three-column methods
- Wide portfolio of AOX and AOF columns and activated carbon – prefilled disposable columns and re-usable quartz columns
- Comfortable, easy operation by integrated control – no extra PC required
AOX, AOF and EOF analysis made profitable
Reach a new benchmark in AOX, AOF and EOF analysis efficiency! 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
