UV Testing Process:

Ultraviolet (UV) testing is one of the most common methods used to test Lutein Powder. This process is used to measure the concentration of Lutein in the powder sample. Here are the steps involved in the UV testing process: 

 

1. Preparation of Lutein Sample Powder :

 A small amount of lutein powder is accurately weighed and dissolved in a suitable solvent to obtain a clear solution. 

 

2. Setting up of UV spectrophotometer: 

A UV spectrophotometer is set up and calibrated to the required wavelength for lutein powder detection. 

 

3. Loading the sample: 

The sample is loaded into a sample holder and inserted into the UV spectrophotometer. 

 

4. Absorption measurements: 

The UV spectrophotometer measures the intensity of light absorbed by the Lutein in the sample. This measurement gives an idea about the concentration of Lutein in the sample. 

 

5. Determination of concentration: 

Using the obtained absorption measurements, the concentration of lutein powder in the sample is calculated using the Beer-Lambert law.
