Automation Brings Flexibility to Discrete Analysers

SEAL Analytical provided visitors with an opportunity to see the latest technologies in both automated discrete analysers and segmented flow analysers. The AQ400 automated discrete analyser manufactured by SEAL in the US, has been designed to provide greater speed and capacity, with improved reproducibility and greater flexibility. It has all the advantages of discrete analysis; auto-standard preparation, auto-dilution, automatic method changeover and low reagent consumption. Regulatory approved applications (EPA, ISO) include nutrients such as nitrate, nitrite, ammonia, phosphate, Chromium VI, TKN, TP etc. in water, wastewater, soils, extracts and digests.

The AQ1 and AQ2 discrete analysers, offering users minimal operator involvement and the ability to run many different chemistry tests from each sample in the same run were also shown along with automated  segmented flow analysers for laboratories requiring high throughput, accurate analysis with very low detection limits for very large numbers of samples. the re will be an opportunity to see automated segmented flow analysers (the QuAAtro39 for example can run up to 600 tests per hour).

The company’s expert chemists were also on the stand to help customers decide which method best meets their needs. There are new methods for ammonia with in line gas diffusion automated sample preparation and phenol with in line distillation, which can be run on the AA1, AA3 and QuAAtro39 analysers.

SEAL also featured the Thomas Cain automated sample preparation and digestion systems. for the analysis of metals in environmental laboratories.
