More about the AQ2+ Nutrient Analyser

Advanced Discrete AnalyzerHighly AutomatedSimple to UseLowest Reagent ConsumptionCompact DesignThe AQ2+ employs a robust robotic sampling arm working in conjunction with a stepper motor-driven syringe that is responsible for aspirating, dispensing and mixing accurate and precise quantities of sample and reagent in miniaturized test tubes called reaction wells.The sample and reagents are incubated in the reaction wells for a preprogrammed time. A single aliquot is then transferred into a glass optical cuvette. The absorbance is then read on the stationary reactant to ensure the best possible signal to noise ratio.The reaction times are user programmable from seconds to minutes. The standard methods supplied have optimized reaction times which ensure the reaction is brought to completion. This complete reaction emulates the manual and segmented flow methods. This eliminates the problems encountered with flow injection analysis where the reaction is not brought to completion, decreasing sensitivity and potentially introducing kinetic effects.Once the absorbance is read, the cuvette is thoroughly cleaned, eliminating any carryover or cross contamination.How does theAQ2+ work? AQ2+ is Ideal...when many and varied tests are needed on different samples and/or individual results are needed in a short time. AQ2+ Series...is a flexible analyzer that uses the principle of discrete analysis where each test occurs in a separate or discrete reaction vessel.100% optical quality glasscuvette used for preciseabsorbance measurementRobust detection system utilizes stationary measurement cell10 mm optimum path lengthReagent wedges with on-board cooling – only 20-400 µL reagent used per testAutomatic reagent level sensing verifies sufficient reagent volumeReagent expiration date tracked through softwareHighly flexible software designed with user inputQCProTM Data Quality Assurance System – allows the user to specify QC types, limits and correctiveactions upon a QC failureThe AQ2+ Advanced Discrete Analyzer is a fully automated instrumentdesigned specifically for the environmental market. USEPA, ASTM, ISOand other international regulatorycompliant methods are available.

Based on the robust, world class heritage of the original Technicon TM design, these instruments offer exceptional reliability, performance and ease of use for over 1000 available methods.AAce software is a common platform for both instrument series and is intuitive and flexible. Both instruments are especially suitable for ultra low level determinations, such as drinking water and in complex matrices such as seawater with varying salinity.Segmented flow analyzers are compli-mentary to discrete analyzers and areparticularly attractive to labs that routinely run many samples for the same analytes.SEAL Analytical is a global company with offices worldwide - contact us at:SEAL Analytical, Inc.Mequon Technology Center10520-C Baehr Rd.Mequon, WI 53092United StatesTel: +1 (262) 241 7900Fax: +1 (262) 241 7970Email: sales@seal-us.comSEAL Analytical Ltd.67 Victoria Rd.Burgess HillSussex RH15 9TRUnited KingdomTel: +44 (0) 1444 872600Fax: +44 (0) 1444 871495Email: mail@seal-analytical.comSEAL Analytical GmbHWerkstrasse 4D-22844 NorderstedtGermanyPhone: +49 40 522 02 100 Fax: +49 40 522 02 473Email: info.germany@seal-analytical.comwww.seal-analytical.comDistributed By: Fluidquip Australia Pty Ltd12 Carl Court, Hallam.
