How to Measure the Color of Powders With the ColorFlex L2

Loose powders present several color measurement challenges, from nonuniform samples to light interference. These challenges exist across everything from powdered chemicals to cocoa and baking powder. The ColorFlex L2 overcomes all the challenges of powder color measurement, offering an easy-to-use design and high-quality results. 

The Difficulties of Powder Color Measurement

Understanding the challenges faced in color measurement enables you to address them more effectively. Here are the most common issues in collecting spectral data for powders:

• Nonuniformity: Powders consist of tiny particles that appear differently depending on how they are prepared. 
• Light sensitivity: Powders cause light trapping, shadowing, and ambient light interference, which can result in inaccurate measurements. 
• Sample size: Powders often consist of a small amount of material, but the sample must be thick enough to create an opaque layer. 
• Fluorescence: Powders are sometimes affected by UV light, which influences their measurement results without adequate controls.

The Solution: HunterLab's ColorFlex L2

The ColorFlex L2 is a highly accurate, user-friendly spectrophotometer, minimizing the difficulties of sample preparation, even for small sample sizes. It includes an internal camera for positioning and controlled UV measurement for diverse samples, including fluorescent powders. This solution's design enables it to work with various sample types, allowing it to meet all the challenges that arise with powders. It's a reliable tool for numerous tasks, including baking powder color measurement.  

How the ColorFlex L2 Enhances Your Processes

This solution delivers advanced features that provide advantages for spectral data collection, including:

• Ability to use many different industry-standard color scales, depending on your measurement application
• Immediate pass/fail results using a light ring indicator so you know before checking the data
• Advanced software for improved reliability, even with more difficult samples such as powders
• Compatibility with necessary color measurement accessories for powders, including sample cups and opaque covers

Operating the ColorFlex L2

Here's how to use this device for tasks like cocoa powder color measurement:

1. Configure it for the desired color scale, illuminant, observer, and averaging. 
2. Standardize the device for a new measurement. 
3. Scoop powder from the sample batch and fill the sample cup to the top. 
4. Tap the cup on a hard surface to settle the powder, then put it in the sample holder in the spectrophotometer and cover it with the opaque cover. 
5. Take three measurements for an average value, dumping and refilling each time. 
6. Export or print spectral data or share video recordings for further review and decision-making.
