We have a Cary7000 with UMA - we have a method that measures each sample at sample angles 6 degrees through 76 degrees, using scan though each wavelength from 200nm - 2500nm. When we measure in increments of 10 degrees or 2 degrees (for sample angle) we get different reflectivity values for common angles across the range. Why is this? The method is exactly the same, using the same bassline, taken within 24 hours of each other.
