The multi-parametric analyzers are designed to determine a wide range of analytes and are the best instruments for beverage analysis as they allow simultaneous determination of the parameters desired.
Direct reading analyzers follow the principle of photometry where the change in absorbance is proportional to the concentration at different wavelengths. They use comparative analysis such as Fourier Transform Infrared Spectroscopy (FTIR) and are particularly suitable for a wide range of analytes in various matrices.
