SEAL AQ2 Discrete Analyser

The Discrete Analyser AQ2  by SEAL Analytical is a nutrient analyser specifically designed for the environmental market that uses the principle of Discrete Analysis. Each test occurs in a separate or discrete reaction vessel. Discrete Analysers allow multiple tests on a single sample; varied tests on a single sample; ultra Low reagent Use and up to 150 tests per hour. The AQ2 Discrete Analyser features: Programmable reaction times; Chemistry that is brought to full completion; 100% Optical Quality Glass Cuvette.

The AQ2  Discrete Analyser employs a robust robotic sampling arm working in conjunction with a stepper motor-driven syringe. The syringe is used for aspirating, dispensing and mixing accurate and precise quantities of sample and reagent into miniaturized test tubes, called reaction wells.

In the AQ2 Discrete Analyser the sample and reagents are incubated in the reaction wells for a pre-programmed time. A single aliquot is then transferred into the Optical Quality Glass Cuvette. The absorbance is read on the reactant in our stationary optical bench to assure the best possible signal to noise ratio.

This nutrient analyser's reaction times are user programmable from seconds to minutes. We have optimised the SEAL AQ2 Discrete Analyser methods to ensure that the chemical reaction is brought to full completion and steady state. This completed reaction exactly emulates both the Manual and the Segmented Flow Methods.

In the AQ2 Discrete Analyser the chemical reaction comes to a full steady state eliminating the problems inherent in the Flow Injection Analysis Methodology. The Flow Injection System does NOT bring the reaction to full completion, decreasing sensitivity and potentially introducing kinetic effects. Once the absorbance is read, the cuvette is thoroughly cleaned, eliminating any carry over or cross contamination.

SEAL Discrete Analyser Advantages

Commonly, laboratory analysers are designed for specific applications and markets, and then as the technology matures alternative applications are uncovered. The Discrete Analyser is no different, being initially designed as a clinical analyser, and later presented to environmental users as a way to reduce costs, increase throughput and reduce waste in laboratories. 

In the early 2000’s SEAL Analytical was formed as the environmental arm of Synermed- a clinical UK based company.  SEAL quickly found obstacles to using clinical analysers in environmental markets, and they subsequently designed a Discrete Analyser to overcome these obstacles. The result is the AQ2 Discrete Analyser- an analyser designed specifically for environmental analysis. Today SEAL has the largest installed base of Discrete Analysers in the USA and they continue to develop the software and hardware for the specific needs of environmental users. 

Key Advantages

  • Walk-away operation
  • Segregated chemical waste and wash minimises environmental impact
  • Only 500 – 600 μL of combined reagents and sample consumed per test
  • Add samples after a run has started
  • Automated standard preparation and two dilutions over over-range samples
  • Lower detection limits
  • Will run up to 150 tests per hour
  • Tests programmable per sample to reduce analysis time
  • Better reproducibility
  • Pre-dilutions can also be scheduled
  • High throughput- with up to 18- tests in a single run
  • Schedule up to 7 tests on a single sample
  • Best value Discrete Analyser on the market

Main clinical analyser design issues addressed by the AQ2

The Mixing of Samples and Reagents- mixing of samples and reagents is critical, however in some analysers it is not very effective, which means the results are not reproducible.   Instead, the AQ2 approximates mixing in a flask by repeatedly “sucking and spitting” samples and reagents, rather than simply stirring. The SEAL approach is the most effective way to mix, and it also limits moving parts.

Cross Contamination- with Discrete Analysers using the same probe to pick up samples and reagents and flicking droplets over the system, the cross contamination of cells is a real possibility.  The AQ2 completely negates cross contamination opportunities by being the only discrete analyser with 3  wash stations, including flushing of the probe (on the outside before it moves anywhere) and a fixed wash pot that is continually filled with fresh DI water. This means the AQ2 is the only Discrete system that can run nitrate & ammonia together with no cross contamination (as nitrate uses NH4CI buffer).

Cuvette Path Length- most Discrete Analysers used in clinical tests use a shorter path length (6 or 7mm), important in clinical tests where reactions are enzymatic, and reagents so expensive (the smaller the cell, the less reagent us used).  These shorter path lengths lower the signal and result in a higher detection limit. The AQ2 includes the accepted and optimum EPA path length of 10mm, which results in lower detection limits, critical for environmental analysis.

Styrene Cuvettes- many Discrete Analysers use styrene reaction wells from which measurement is taken. These are not only more expensive (increasing the cost per test), they scratch easily and are not optically pure, leading to reproducibility issues. The AQ2 uses low cost, disposable reaction wells and measurement is performed in 100% optically pure glass cuvette.

Higher Detection Limits- most Discrete Analysers not designed specifically for environmental applications have higher detection limits resulting from the combination of mixing techniques, shorter path lengths, and non-optical cells. 

Greater Reproducibility- all clinical analysers are direct read. SEAL was aware that flow systems gave the lowest and most reproducible results and ensured this design feature was included in the AQ2. The AQ2’s readings are done in:

  • 100% optically pure glass cuvette (which is not a consumable, and it stays in the detector)
  • With each sample read in exactly the same position, resulting in no alignment issues
  • Inert and easily cleaned glass, with a blank measurement done between each sample
  • A Hellma cuvette, which is exactly the same as those used in spectrophotometers (it is not a flowcell)
  • A static sample, which is then washed out thoroughly, a blank done and then the next sample is put in.

Comparison of a Block Digestion System to beakers on a hot plate

The SEAL Analytical Block Digestion System provides better quality results, higher productivity of sample throughput and uses less fume hood space per sample. It's also an automated process and frees the operator to perform other tasks. Digesting samples in a beaker on a hot plate requires constant vigilance and care. A Block Digestor allows you to digest 50 samples simultaneously with minimal operator supervision. All samples on a Block Digestor are processed at exactly the same temperature. Because hot plates have hot and cold spots, all samples are often digested at different temperatures, giving inconsistent/ incorrect results. A Block Digestor regulates the exact digestion time and heating rates, whereas on a hot plate, the times are dependent upon an operator to remember to change the digest conditions.


 

Comparison of Block Digestion Systems to Microwave Digestion System

While microwave digestion systems can accelerate the digestion process, block digestion systems still offer a number of distinct advantages:

Larger runs- the SEAL BD28s and BD50s  block digestion systems digest more samples and larger sample sizes  in one batch. On a microwave digestion system, you are limited to 0.5g for inorganic samples, less for organic samples, the BD28s and BD50s allow you to use ten times this amount.

Less operator involvement- a microwave digestion system requires regular attention by the Operator, disassembling and reassembling digestion vessels. on the BD28s and BD50s, once you add samples and acid, digestion proceeds without intervention by the operator. The high operator involvement for the microwave digestion unit tends to negate the faster digestions.

More flexibility- It is possible to use a wider range of acids including sulphuric acid and perchloric acid on the BD28s and BD50s. On a microwave digestion system, sulphuric acid has too high a boiling point and will melt the PTFE vessels while perchloric acid can be explosive under pressure. It is not possible to perform kjeldahl digestions in a microwave system but you can on the BD28s and BD50s Block Digestion Systems.

Cost-The BD28s and BD50s Block Digestion Systems are much cheaper than microwave digestion systems, typically about a quarter of the cost. Microwave digestion systems also have on-going consumable costs, such as rupture membranes and digestion vessels have finite life. The BD28s and BD50s have no on-going consumable costs.
