Orion Star T900 Series Titrators Product Introduction MK Malhotra The world leader in serving science
Titration Basics • Titration: • Technique that is based upon the addition of a reagent (titrant) that reacts with the sample species • As reagent is added, the changes in electrode potential are recorded • The sample concentration is calculated from the volume of reagent that is chemically equivalent to the sample species • Automated Titrator: • The device used to perform the titration, titrant standardization or direct measurement 2
Titration Basics • Equivalence Point / Inflection Acidity Titration (Equivalence Point) Point Titration: 12 11 • Technique of adding small aliquots of a titrant to the sample, recording 10 the potential changes, and 9 applying a first derivative analysis 8 to the data, from which the pH Value endpoint is calculated 7 • The technique assumes that the 6 change in mV reading per volume 5 of titrant added will be greatest at the endpoint 4 3 • This technique is a very precise technique for performing routine 2 0.0 0.5 1.0 1.5 2.0 2.5 titrations mL of NaOH Added 3
Titration Basics • Preset Endpoint Titration Acidity Titration (Preset Endpoint) 9 • Type of titration where aliquots of the titrant are added until a 8 predetermined mV or pH value is reached 7 • This is a fast way to do a titration, 6 but requires that the sample and pH Value its reaction with the titrant be well 5 known • The preset endpoint technique is 4 useful for analyses without a clearly defined endpoint and is 3 often a technique required by industry standards 2 0.0 0.5 1.0 1.5 mL of NaOH Added 4
Titration Basics • Our core electrochemistry technology integrated with state- of-the-art reagent dispensing system to create a modern, simplified automated titrator • Designed to make performing titrations easier, more reliable and more reproducible than manual titrations • Expands the number of chemicals that can be measured beyond direct electrode analysis • Offers dynamic process controls that adjust the titration to optimize analysis results 5
