Lovibond: Accurate color analysis of liquid and solid samples
Evaluate the color of your products with Lovibond
Lovibond , and other materials using standardized reference scales. Its accuracy and reproducibility make this technique essential for industries requiring rigorous color control, including the food, petrochemical, and pharmaceutical sectors.
Lovibond helps ensure product compliance with international standards and ensures consistent visual quality for consumers and end users .
How does Lovibond color measurement work?
Lovibond is based on precise color assessment using a combination of optical filters and standardized light sources. Its principle is based on several steps :
- Sampling – The liquid or solid sample is placed in a cuvette or measuring container.
- Standardized illumination – A specific light source illuminates the sample to minimize variations due to environmental conditions.
- Comparison with colorimetric filters – The intensity and hue of the sample are compared to reference filters, often aligned to scales such as Lovibond RYBN (Red, Yellow, Blue, Neutral) or the Gardner scale.
- Reading and interpretation of results – The values obtained are translated into numerical indices allowing the color of the sample to be precisely classified.
This method guarantees repeatable and comparable measurements between different production batches.
Technical characteristics of Lovibond
Lovibond measurement is designed to provide high accuracy and meet the requirements of various industrial sectors. Its features include:
- Measuring systems : visual comparison (manual models) or digital analysis (spectrophotometric devices).
- Measuring scales :
- Lovibond scale : measurement of red, yellow, blue and neutral (RYBN) hues.
- Gardner scale : used for oils and resins.
- Saybolt scale : intended for clear hydrocarbons and fuels.
- Hazen scale (APHA) : for clear and slightly colored liquids.
- Accuracy : standardized measurement with calibrated filters and light sources that comply with international standards.
- Types of samples analyzed : transparent liquids, oils, chemicals, plastics, resins and semi-solid foods.
Some models feature digital connectivity to facilitate the integration of results into a quality management system.
For which matrices is Lovibond analysis suitable?
Lovibond Color is designed to analyze a wide range of matrices, from transparent liquids to semi-solid materials:
Thanks to its ability to measure varied samples with great precision, color analysis by Lovibond is a key tool for quality control laboratories and manufacturers concerned with optimal control of the color of their products.
Main industrial applications of Lovibond measurement
Lovibond is an essential tool for industries where product color is a major quality criterion. It is particularly used in the following areas
:
Lovibond measurement allows manufacturers to ensure the conformity of their products and avoid unwanted color variations.
