This article provides details on measuring ICUMSA using the VISTA.
Note: In Vista Essentials 1.04.0056 and above, ICUMSA 420nm and ICUMSA 560nm are added into the list of color indices. If you have Vista Essentials before 1.04.0056, please download the latest Vista Essentials .apk file and install it in your Vista.
In the default Indices list, user can find ICUMSA 420-10mm and ICUMSA 560-10mm.
Before using ICUMSA 420/560, please enter the correct weight% and density (g/ml) of the sample in Custom Indices. Density (g/ml) should range from 0.5 to 2. Weight% (g/g) should range from 1 to 100. Degrees brix is the % w/w of soluble solids in a solution. For example, a Brix50 solution has a weight% of 50. The density of sugar solutions with a different brix degree can be found in a lookup table.
If user prefers to use the other path length instead of 10mm, please go to Custom indices to add ICUMSA 420/560 in other path length. Path length can be any number between 0-100mm.
