Step-by-Step Guide to Measuring Fluorescence Intensity and Wavelength Accuracy (Including 980nm)

Accurately measuring fluorescence intensity and wavelength accuracy is crucial for quality control. For pigments like IR980nm, which emit in the infrared spectrum, specialized equipment is necessary. Start by preparing a controlled sample of your pigment dispersed in the intended medium (resin, solvent, etc.). Use a spectrofluorometer to excite the sample with a specific wavelength and measure the emitted light. The spectrofluorometer will provide data on the intensity and wavelength of the emitted fluorescence. Ensure your instrument is properly calibrated and use consistent settings for each measurement. For IR980nm, confirm that your detector is sensitive in the 980nm range. Compare your measurements against the pigment supplier’s specifications to verify the pigment’s performance and identify any deviations. Consistent and accurate measurements are essential for identifying batch-to-batch variations and ensuring product consistency.

Troubleshooting Common Issues: Dispersion Challenges in Water-Based vs. Solvent-Based Systems

Proper dispersion is critical for achieving uniform color and optimal fluorescence. However, dispersion can be challenging, especially when working with different base systems. Water-based systems often require the use of surfactants or dispersants to prevent pigment agglomeration. Solvent-based systems may face challenges due to pigment polarity differences. If you observe streaking, settling, or reduced fluorescence intensity, it’s likely due to poor dispersion. Experiment with different dispersants or adjust the mixing process to improve pigment distribution. Consider the pigment’s surface treatment – some pigments are specifically treated for better compatibility with water-based or solvent-based systems. If you encounter persistent dispersion issues, consult with your Fluorescent Pigment supplier for tailored recommendations.
