Can you suggest an alternative procedure for the determination of RTH?

An alternative procedure for the determination of Residual Thermal Haze (RTH) could involve using spectrophotometry to measure light scattering in a sample. This method entails preparing a sample solution, allowing it to stabilize, and then analyzing the absorbance at specific wavelengths. Comparing these readings against a standard curve generated from known concentrations can provide a quantifiable measure of RTH. Additionally, employing chromatography techniques may help isolate and identify components contributing to thermal haze.
