ADI 2016 / 2018 / 2019Automatic and dependable On-line Ion AnalysisThe single method Process Analyzers ofMetrohm Applikon B.V. can be applied inmany different industries to analyze andcontrol their wet chemical processes.The single method analyzers areavailable for:TitrationsADI 2016 TitrolyzerIon Selective measurementsADI 2018 Ion-AnalyzerColorimetric analysisADI 2019 Process Colorimeter• Many proven applications in the analysis of wet chemicalprocesses are available for (petro)chemical-, mining-, semiconductor-,pulp-, paper-, textile-, food- and many otherindustries for process as well as effluent streams.• A flexible wet part containing modules like valves, samplingdevices, pumps, sensors etc. and the flexibility in setting upprogram runs, measuring ranges and result calculation allowa configuration for almost every application.• Easy operation by use of programmable macro’s withdialog functions.• Combination of corrosion resistant plastic and epoxycoated steel, or fully stainless steel cabinets.• Electronics fully shielded from the so-called wetpart.• Ingress protection according to IP65 and NEMA 4X.• Smart design of hard- and software and application ofspecial analytical methods allows automatic calibrationand validation of the results.• Batch-wise operation allows the analysis frequency to bedefined, which leads to a significant reduction in reagent usage.• A flexible design makes it possible to automate yourlaboratory method ensuring that the analyzer generatesthe same result as your laboratory.AutomationThe analyzers can run three different programs which canconveniently be adapted to the specific needs of the application.• A Clean program for periodic cleaning of sampling device,analysis vessel or cuvette and sample lines.• A Reference or calibration program for periodicallyperforming a reference analysis on a standard. A titrantor electrode offset can automatically be adjusted.• An Analysis program for on-line sample analysis.The programs are executed in a user definable sequencewith a user selectable time interval. Conditional actionsbased on the result outcome are available to trigger alarms,increase/decrease analysis frequency, and perform Cleaningand Reference programs.
Metrohm Applikon / Single Method On-line AnalyzersADI 2016TitrolyzerAnalysis techniquesThe ADI 2016 Titrolyzer performs potentiometric titrations bymeans of a high precision burette system and high-performanceelectrodes:• Acid/Base titrations• Redox titrations• Precipitation titrations• Karl Fischer titrationsA self finding inflection point technique can be applied for most applications.This can be performed either with fixed time interval additionsor with drift controlled additions, depending on the application.For some applications also a (temperature compensated) end-pointtechnique is available. Karl Fischer titration is a special version of that.TitrationTitration is one of the most applied and proven analysistechniques. This can be explained by the fact that it usesvery straightforward instrumentation and yet delivers mostaccurate analysis results. This is also reflected in thefollowing features brought by the ADI 2016 Titrolyzer:No need for calibration since titration is an absolutemethod.Also the applied electrode does not need calibrationbecause the inflection point is derived from the measuredpotential differentials, rather than the absolute potentials.Great selectivity through the use of dedicated titrantsand electrodes.Several parameters can be obtained by multipointtitration, e.g. P and M number, or Alkalinity andCarbonate.1211109pH876543210EP2EP11 2 3 4 5 6 7 8 9V (ml)
