Overview

Summary

Thermo Scientific™ Orion Star™ T900 series laboratory titrators are designed to increase your lab productivity by automating potentiometric titrations. These compact titrators are simple to use with easy navigation from setup to live titration analysis to data transfer, all on a large color graphic touchscreen display. Create and save up to ten custom user-defined methods or use preprogrammed protocols, all with onscreen instructions and help menus, so everyone in your lab can be up to speed quickly and easily.

We have integrated our core electrochemistry technology with a state-of-the-art reagent dispensing system to create a modern, simplified automated titrator designed to make performing titrations easier, more reliable, more reproducible and faster than manual titrations. Our automated titrators expand the number of ions and compounds that can be measured beyond direct electrode analysis and offer dynamic process controls that adjust the titration to optimize analysis results.

The Orion Star T900 series titrators include four models, the Orion Star T910 pH titrator, Orion Star T920 redox titrator, Orion Star T930 ion titrator and Orion Star T940 all-in-one titrator. These titrators have the ability to calibrate the electrode (sensor), standardize titrants and perform various types of potentiometric titrations. The Orion Star T930 ion titrator and Orion Star T940 all-in-one titrator offer the added benefit of multiple know addition (MKA) analysis, where the titrator performs an automated calibration and calculation of sample concentration by adding aliquots of standard to sample.

Ideally suited for dedicated, routine measurements, the Orion Star T900 series titrators are designed to help laboratories overcome problems of sample throughput or analytical complexity through automation of analysis. What differentiates the Orion Star T900 series titrators from other single parameter instruments and automatic titrators are their simplicity. All of the setup procedures appear on the display in the form of easy-to-understand, sequential menus. Because the analysis is automated, each titration step is carried out consistently time after time, operator to operator, using a high precision burette that meets ISO 8655 standard. Whether your analysis is acidity of juices, alkalinity of water, surfactants in shampoo, fluoride in drinking water or Vitamin C in juices, the Orion Star T900 series titrators offer a simple system to automate your measurements.

This user manual provides instructions for the Orion Star T910 pH titrator, Orion Star T920 redox titrator, Orion Star T930 ion titrator and Orion Star T940 all-in-one titrator. Detailed information on titrator installation, setup, operation and features is provided in the appropriate sections of this user manual. Please visit www.thermofisher.com/water for additional information on Thermo Scientific Orion instruments, electrodes and solutions.

Use the Orion Star T910 pH titrator for dedicated acid-base titrations including titratable acidity of juices and wines, acidity of food products, alkalinity of waters, acidity and alkalinity of consumer products, total acid number (TAN) and total base number (TBN). Titration techniques include equivalence point titrations and preset pH endpoint titrations.

Use the Orion Star T920 redox titrator for dedicated redox titrations including sulfite/SO2 and reducing sugar in juice and wine, ascorbic acid (vitamin C) and peroxide value in food products, dissolved oxygen in wastewater by Winkler titration and organic matter in soil. Titration techniques include equivalence point titrations and preset mV endpoint titrations.

Use the Orion Star T930 ion titrator for dedicated ion concentration titrations including salt in food products, chloride in drinking water and wastewater, ammonia and Total Kjeldahl Nitrogen (TKN) of wastewater, surfactants in consumer products and total hardness of drinking water and wastewater. Titration techniques include equivalence point titrations and preset mV endpoint titrations plus multiple known addition (MKA) mode. Using MKA mode, the titrator performs an automated calibration and calculation of sample concentration by adding aliquots of standard to sample, removing the need for a separate calibration and minimizing matrix effects.

Use the Orion Star T940 all-in-one titrator for flexible pH, redox and ion concentration titrations including equivalence point titrations, preset pH or mV endpoint titrations plus multiple known addition (MKA) mode for automated known addition of various ions.

Overview | 1

Terminology

The terminologies used in this user manual is explained here

Titrator

The device used to perform the titration, titrant standardization or direct measurement.

Titrant

Reagent of known concentration that is added to a sample and results in an observable reaction and endpoint or equivalence point.

Sample

Solution of unknown concentration that is titrated using a titrant to determine the concentration.

Burette

Component that dispenses a measured volume of titrant into the sample by pulling the titrant from the reagent bottle into the burette and then pushing the titrant from the burette to the dispensing probe and into the sample.

Electrode

Also called probe or sensor, the device in the solution performing the measurement.

Mode

Measurement type being used by the titrator (pH, mV, ISE).

Method

A set of saved parameters and values for a particular titration including the electrode, titrant and titration setup parameters as well as electrode calibration and titrant standardization when applicable.

pH measurements compares the relative acidity or alkalinity of a solution at a given temperature. A pH of 7 describes a neutral solution because the activities of hydrogen and hydroxide ions are equal. When the pH is below 7, the solution is described as acidic because the activity of hydrogen ion is greater than that of hydroxide ion. A solution is more acidic as the hydrogen ion activity increases and the pH value decreases. Conversely, when the pH is above 7, the solution is described as basic (or alkaline) because the activity of hydroxide ion is greater than that of hydrogen ion.

Redox / ORP

ORP (Oxidation / Reduction Potential) measures the oxidizing or reducing nature of a sample. This gives an overall indication of how "reactive" the sample is. ORP measurements are common in water, wastewater, process water and plating bath applications.

ISE (Ion Selective Electrode)

Ion selective electrodes measure the concentration of specific ions in sample solutions such as water, wastewater, consumer goods and pharmaceuticals. Ion selective electrodes are available for ammonia, ammonium, bromide, cadmium, calcium, carbon dioxide, chloride, chlorine, cupric, cyanide, fluoride, fluoroborate, iodide, lead, nitrate, potassium, silver, sodium, sulfide, surfactant and thiocyanate.

All-in-One

Titrator that combines the functionality of the pH, redox and ion titrators into one unit.

Titration

Technique that is based upon the addition of a reagent (titrant) that reacts with the sample species. The changes in electrode potential are observed and sample concentration is calculated from the volume of reagent that is chemically equivalent to the sample species.

Equivalence/Inflection Point Titration

Technique of adding small aliquots of a titrant to the sample, recording the potential changes, and applying a first derivative analysis to the data, from which the endpoint is calculated.

The technique assumes that the change in mV reading per volume of titrant added will be greatest at the endpoint. This technique is a very precise technique for performing routine titrations.

Preset Endpoint Titration

Type of titration where aliquots of the titrant are added until a predetermined mV or pH value is reached. This is a fast way to do a titration, but requires that the sample and its reaction with the titrant be well known. The preset endpoint technique is useful for analyses without a clearly defined endpoint and is often a technique required by industry standards.

Multiple Known Addition (MKA)

Known addition is a technique of adding small aliquots of the species of interest to the sample and calculating the original sample concentration from the observed changes in potential. The electrode chosen for analysis should sense the species of interest. This technique helps minimize matrix effects and offers greater precision than direct calibration measurement.

In multiple known addition, three or more additions are made to the sample allowing electrode slope, Eo, sample concentration and a spike recovery to be calculated. This is a very precise technique because the calibration is performed

directly in the sample matrix during analysis.

Unique benefits of multiple known addition include the level of precision of the analysis may be chosen and each sample analysis is automatically verified by a spike recovery analysis.

Orion Star T900 Series Laboratory Titrator

Direct Titration

Technique in which the titrant reacts directly with the chemicals in the sample solution and titrant consumption is directly related to the quantity of the chemicals in the sample.

Back Titration

Technique in which excess quantity of a reagent is added to the sample, so that the entire sample reacts with the reagent and some un-reacted reagent remains. The un-reacted excess reagent is titrated with suitable titrant. If the amount of reagent added to the sample is known, the sample concentration can be calculated.

Blank Titration

A blank is used when performing a back titration or when a background correction is necessary (background level of the measured species is present prior to analysis). The blank value can be manually entered or calculated by performing a titration. If a blank value is entered, make sure that all samples analyzed by that method are prepared in the same manner. Most routine titration methods do not require a blank.

ROSS pH Electrodes

Not all pH electrodes are created equal – It is critical that the measurements customers perform day-to-day are accurate and reproducible. Customers rely on their pH electrodes to measure their samples quickly and precisely, making pH electrodes an essential part of the lab. ROSS pH electrodes offer superior measurement stability, fast response, high accuracy and precision even in samples with varying temperatures, no long-term drift and long lifespan.

Orion Ion Selective Electrodes (ISEs)

Measurement by an ion selective electrode (ISE) can be performed in virtually every laboratory. Efficient and Economical - Electrode measurements are simpler and faster than other analytical techniques. Time consuming sample steps such as filtration and distillations are rarely needed and analysis time is typically 1-2 minutes per sample. Compared to other analysis methods, there is a relatively small setup cost. Ion selective electrodes can be used for determination of a titration end point and are useful as end point detectors because they are unaffected by sample color or turbidity.

Orion Electrochemistry Solutions

Customers need to be able to rely on their measurements and using high-quality solutions to calibrate and maintain electrodes is the best way to ensure data is both accurate and reproducible. Using low-quality, home-made, or expired buffers can lead to measurement errors, which require lengthy troubleshooting, or even worse – can go unnoticed. Using high-quality solutions eliminates one of the major causes of measurement inaccuracy.

Orion solutions are manufactured for accuracy and repeatability to the highest quality standard in the industry. Orion solutions are produced in controlled batches using ultra pure water and undergo rigorous quality testing throughout the process to prevent contamination before and after bottling. Buffers and standards have lot-specific certificates of analysis with NIST-traceable testing results.
