Rudolph Research Analytical have recently released an updated version of their multi parameter flavour/fragrance analysis system. that measures specific gravity, refractive index, optical rotation and colour in a run of up to 240 samples without operator intervention. There are two key features that make the system popular with labs. Firstly, the system can be customized to take the sample directly from existing bottles, allowing the QA lab to skip the decanting step. Secondly, since none of the tests are destructive, over 90% of the sample can be returned to the bottle for reuse. This is particularly important when the sample is very expensive or when only a limited sample quantity is available.
