Classical Analytics
Titrations and gravimetric testing are among the most frequently used procedures in analytical chemistry. Most of these »classical« methods are used by CC Analytical Services.
- Titrations
- Potentiometry
- Analytical parameters
- Gravimetry
- Sample digestion and preparation
-
Titrations are used to determine product characteristics such as acid number, saponification number, iodine number or hydroxyl number. Detection of the end point may be visual or potentiometric.
Procedures used:
- Acid-base titrations
- Redox titrations
(e.g., iodometry, permanganometry) - Titrations with ion-selective electrodes
(e.g., surfactant titrations, sulfate titrations) - Argentometry
- Karl Fischer titration

Analytical parameters are used to characterize organic and inorganic substances with standardized methods.
Physical parameters Chemical parameters - Color number
- Density
- Melting point
- Viscosity
- Particle size distribution
- Ash/sulfate ash
- Water (Karl Fischer)
- Dry substance/evaporation residue, etc.

Gravimetry usually permits determination with a substantially higher accuracy. It is therefore often used as a check for other methods, even though it is relatively time-consuming.
Applications of gravimetric determinations: - Moisture content
- Dry weight
- Evaporation residue
- Ash content
- Sulfate ash
- Metal ions

CCA uses a variety of automated procedures for digestion or sample preparation before the analytical determination itself.
Focus of digestion procedures: - Acid
- Fusion
- Microwave
