1. Notable features of Hydranal Composite 5
- Composition: HYDRANAL Composite 5 is the titrant in the Karl Fischer method, combining iodine, sulphur and catalysts (called reagents) that drive the reaction to completion.
- Performance: works well with different sample types, including organic and inorganic compounds. High stability, which ensures consistent measurement results throughout the experiment.
- Safety: reduces toxicity compared with conventional Karl Fischer solutions.
2. Hydranal Composite 5 specifications
- Iodine content: about 5 mg/mL.
- Solvent: methanol mixture.
- Accurate water content: about 5 mg H2O/ml (±0.05 mg H2O/ml)
- Stability: high, suitable for accurate measurement over long periods.
- Ready to use: used directly, without dilution or additional treatment.
- Volume: available in several pack sizes: 500 mL, 1 L.
- Accuracy: ensures deviation does not exceed 0,1%.
3. Applications
HYDRANAL Composite 5 is widely applied in many fields, used to analyse water content in oils, solvents, plastics, food, chemicals and pharmaceuticals.
- Food industry: determination of water content in oils, butter, milk powder, etc.
- Pharmaceutical industry: checking moisture in raw materials and finished products.
- Chemical industry: quality control of chemical solutions, lubricants and polymers.
4. Benefits of using HYDRANAL Composite 5
- Saves time thanks to high accuracy, minimising the risk of deviation.
- Easy to use for many different applications.
