JOHN Morris Scientific can now introduce customers with concerns about colour accuracy, to the UK-based Tintometer Lovibond Colour Laboratory.

The Colour Laboratory is a specialised colour analysis service that is available on a test-by-test basis, or as an out-source facility to laboratories around the world.

It is suitable for a broad range of sample types, such as mineral and industrial oils and fuels, chemicals, waters, effluents, pharmaceuticals and foods and beverages.

Using experienced colorimetry technicians and master instruments to obtain the colour data, Lovibond's Colour Laboratory can carry out measurements to all relevant International and other trade standards and specifications.

All samples are measured under the control of Lovibond's ISO 9001:2000 Quality Management System.

In addition, Lovibond has been awarded UKAS (United Kingdom Accreditation Service) accreditation as a calibration laboratory for spectral response and CIE measurements.

As a result, it can supply colour measurement data that are directly traceable to national standards.

Colour analysis and observations are conducted using methodology specified by the customer, who is supplied with a Colour Laboratory report stating the instrument used, colour values obtained by sample reference, measurement conditions and observations.

John Morris Scientific provides the complete range of Lovibond colour measuring instrumentation. Lovibond colorimeters are used for analysis in the chemical, petrochemical, pharmaceutical and medical industries, and also in the manufacturing of food and beverages.

Indeed, the Lovibond brand has become the hallmark for colour measurement across many industries, and is recognised by major international standardising bodies such as ASTM, ISO and IP, who quote its equipment in their specifications for colour measurement.

Colour measurement is necessary to quantify and assess a product's colour, or where colour is an indirect measure of product quality or processing performance.

However, industry standards and specifications for colour measurement vary widely by product type, depending on colour characteristics and historical acceptance.
