Titrasyon, analitik kimyadaki en eski yöntemlerden biri olup, çeşitli endüstrilerde iyi bir şekilde yerleşmiştir. Uygulama uzmanlarımız, titrasyonun çeşitli uygulamalarını sunan çok sayıda belge derlemektedir. Asit-baz titrasyonu, redoks titrasyonu veya çöktürme titrasyonu gibi farklı titrasyon türleri ve ayrıca gıda endüstrisi, çevre endüstrisi veya ilaç endüstrisi gibi farklı endüstriler ele alınmaktadır.
Titrasyon uygulamalarımızı analit/parametre, numune matrisi, norm veya endüstriye göre aramak için filtreleri kullanın.
- AN-T-239Nonaqueous titration of weak bases with perchloric acid
The amine value is an important parameter and quality indicator to determine in chemical processes and pharmaceuticals. This Application Note presents the nonaqueous perchloric acid titration of triethanolamine.
- AN-T-240Total acid number with conductometric titration
The total acid number (TAN) is an important parameter for assessing the acidity of oils and fuels. This Application Note determines TAN using conductometric titration.
- WP-068Recommendations for titration methods validation
The objective of validation of an analytical procedure is to demonstrate that it is suitable for its intended purpose. Recommendations for the validation of analytical methods can be found in ICH Guidance Q2(R1) Validation of Analytical Procedures: Text and Methodology and in USP General Chapter <1225> Validation of Compendial Procedures. The goal of this white paper is to provide some recommendations for the validation of titration methods.
- WP-063Recommendations for converting a manual titration procedure into an automated titration procedure
This white paper summarizes the steps involved in converting an existing manual titration procedure to semi-automated or automated titration procedures. It discusses topics such as selecting the right electrode and titration mode. For a better understanding, the discussion topics are illustrated with three examples.
- WP-093Significant cost savings through dynamic ventilation during nitrification in wastewater treatment
This White Paper gives an overview of the energy-intensive nitrification process that converts ammonia into less harmful nitrogen compounds at wastewater treatment plants (WWTPs). It displays the results from a field test at a WWTP, showcasing the positive influence of single-method process analyzers on the efficiency of the nitrification process.
- AN-PAN-1032Monitoring corrosion in power plants with online process analysis
Corrosion in the water-steam circuit of power plants leads to shorter lifetimes of most metal components and potentially dangerous situations. Flow Accelerated Corrosion (FAC) is a specific case, leading to thinned pipes and elevated Fe concentrations in the circuit. Additionally, metal transport issues such as with Cu from copper heat exchangers can lead to deposition on the high pressure turbine blades, decreasing their efficiency. Current methods can monitor but not prevent these issues, and analysis times are extremely long (up to three weeks). In combination with the power plant’s Distributed Control System (DCS), online monitoring of Fe and Cu with the 2060 Process Analyzer from Metrohm Process Analytics ensures that corrosion can be controlled before it affects the power plant efficiency, ultimately decreasing downtime and lowering maintenance costs. Results are offered within 20 minutes, allowing fast adjustments to the water-steam circuit to protect company assets.
- AN-T-068Determination of coconut oil ethoxylates (nonionic surfactants)
This application note shows how coconut oil ethoxylates can be determined via potentiometric titration.
- AN-T-067Determination of tallow ethoxylates (nonionic surfactants)
Tallow amine ethoxylates are toxic to aquatic life, and therefore their use is restricted. This Application Note explains an approach to determine these non-ionic surfactants potentiometrically.
- AN-T-015Nonionic surfactants in liquid household cleaners
This application note shows a reliable way to determine the content of non-ionic surfactants in liquid cleaning solutions by potentiometric titration.
- AN-T-050Nonionic surfactant nonylphenol ethoxylate (8 EO)
This application note describes the determination of nonylphenol ethoxylate by potentiometric titration with sodium tetraphenylborate using the NIO surfactant electrode.
