- AN-T-136Epoxide equivalents in epoxy resin
The epoxy content of epoxy resins has a strong influence on the reactivity of the resins as well as on the properties of the coating obtained from the resin curing process. The epoxy content is thus an important quality control parameter for manufacturers as well as consumers. This analysis is based on the reaction of hydrogen bromide with the epoxy groups of the sample. Hydrogen bromide in turn is produced by the reaction of tetraethylammonium bromide (TEABr) with standardized perchloric acid. The standards EN ISO 3001 and ASTM D1652 describe the determination of the epoxy content expressed as epoxy equivalent weight (EEW) by titration. The use of a Titrando and Solvotrode easyClean instead of manual titration greatly increases the reproducibility and repeatability of the determination.
- 8.000.60248.000.6024Fully automated sample preparation for the content determination of tablets
Benzbromaron is one of the main uricosuric drugs currently used. In addition to sophisticated and expensive LC-MS and GC-MS methods, benzbromaron can be effectively determined by titration with sodium hydroxide solution using a straightforward, fully automated sample preparation method. A high-frequency homogenizer comminutes one or three tablets within 90 or 120 s respectively. The overall analysis time is 8 minutes. Ten-fold determinations with one and three tablets resulted in a benzbromaron content of 99.2 and 98.7 mg per tablet respectively. Increasing the number of tablets from one to three lowers the RSD from 1.36 to 0.88%. These results show an excellent agreement with the benzbromaron content indicated by the manufacturer (approx. 100 mg/tablet).Besides the presented Titrando/homogenizer combination, the other two members of the 815 Robotic Soliprep Sample Processor family offer comprehensive sample preparation possibilities within the fields of IC, HPLC, ICP or voltammetry.
- AN-T-195Determination of nitrogen content
Kjeldahl method is used to determine the nitrogen content in organic and inorganic samples. Kjeldahl consists of three steps: digestion, distillation, and titration. During the catalytic digestion step, organic nitrogen is converted into ammonium. Sodium hydroxide is added just before the distillation step for converting ammonium into ammonia. Through steam distillation the latter is transferred into the receiver vessel containing an absorbing agent (e.g., boric acid). Finally, the separated ammonia is titrated against sulfuric acid. Protein content in samples can also be determined from the nitrogen content obtained by Kjeldahl setup. USP describes the titration method to determine nitrogen content in organic products using Kjeldahl nitrogen setup. This Application Note illustrates nitrogen determination in heparin sodium.
- AN-T-055Determination of Lauryl Sulfate
Due to its price and wide availability, the anionic surfactant sodium lauryl sulfate (SLS; SDS) can be found in many detergents as an emulsifier or as a fat solvent e.g., in cleaning or cosmetic products. To avoid causing severe dry skin and hair, and thus skin irritation, regulations in many countries have restricted the sodium lauryl sulfate concentration in ready-to-use products to a range between 0.05–2.5% SLS. To control the concentration of SLS in different products, a titration is carried out with TEGO® trant A100 and the Optrode. The evaluation is done automatically by means of a software, leading to reliable and reproducible results.
- AN-T-132Titratable acidity in milk and yogurt

- AN-T-208Nicotine in e-liquids
The vaping and electronic cigarette industries have grown impressively in the past decade. The mixtures used in these products are usually called «e-liquid», «e-fluid», or «e-juice». To ensure the quality of these e-liquids, testing the most important quality parameters, such as nicotine content, is required. Nicotine in tobacco is usually determined by gas chromatography or liquid chromatography. Aqueous acid base titration is a much more affordable alternative for this determination. As e-liquids do not contain other components which might interfere with the titration, the aqueous acid base titration presented in this Application Note can be applied for nicotine determination. This method is an affordable and reliable way to determine the nicotine content in e-liquids and their nicotine starting material, ensuring the quality of these products.
- AN-K-070Water in petroleum products
Moisture in petroleum products causes several issues: corrosion and wear in pipelines and storage tanks, an increase in debris load resulting in diminished lubrication, blocked filters, or even harmful bacterial growth. As a result, increased water content can lead to infrastructure damage, higher maintenance costs, or even unwanted downtimes.Coulometric Karl Fischer titration is the method of choice for low water content in petroleum products. Using a Karl Fischer oven to vaporize the water present in the sample prior to titration not only greatly reduces matrix interferences, it can also be fully automated. This allows a reliable and cost-efficient analysis of the water content according to ASTM D6304 (Procedure B) in products such as diesel, hydraulic oil, lubricant, additive, turbine oil, and base oil.

Titrating means dosing intelligently. The Titrando System gives you the choice. With the 905 and 907 Titrando you dose with Dosinos and Dosing Units that are attached directly onto the reagent bottle. With the 904 and 906 Titrando dosing is carried out by using Exchange Units. One of these is located on the 904 or 906 Titrando, which can control additional Dosimats with their Exchange Units. Mixed systems with Dosing and Exchange Units are possible. This means that your choice doesnt lead you down a blind alley - full flexibility is retained.
