How Does the AQ400 Discrete Analyser Work?

  • A robust sampling arm works in conjunction with a stepper motor-driven syringe that is responsible for aspirating, dispensing and mixing accurate and precise quantities of sample & reagent in miniaturised test tubes (reaction wells).
  • The sample and reagent are incubated in the reaction wells for a pre-programmed time. A single aliquot is transferred into a 10mm, 100% optical glass cuvette, with the absorbance read on the stationary reactant to ensure the best possible signal to noise ratio.
  • A second robotic arm moves reactant/ sample from the reaction wells to the detection area. The sample is always read in the same position in front of the detector, in the same glass cuvette, eliminating issues of scratching and reaction well variability found with direct read systems. As the liquid is moved, not the tray, fewer moving parts means higher reliability.
  • Supplied standard methods have optimised reaction times ensuring the reaction is brought to completion. The complete reaction emulates the manual & segmented flow methods and ensures the lowest detection limits and good reproducibility.
  • After the absorbance is read, the glass cuvetted is thoroughly cleaned and checked ensuring no carry-over or cross contamination.
  • With the patented probe flusher, water from the wash bottle is pumped through the probe flusher as the probe moves up and down through it to clean the outside before dipping in the next liquid.

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

The SEAL Analytical BD50 and BD28 computer controlled heating blocks 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 the BD50 and BD28 heating blocks are processed at exactly the same temperature. Competing hot plates have hot and cold spots, and samples are often digested at different temperatures, giving inconsistent/ incorrect results. A SEAL computer controlled heating block regulates the exact digestion time and heating rates, whereas on a standard 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.
