Inexpensive Rotating Raman Cell A major problem in Raman spectroscopy is the analysis of colored compounds which absorb the laser light strongly and decompose, often spectacularly. This problem has been solved to a large degree by using a rotating sample holder which moves the sample rapidly out of the laser heam hefore decomposition from heating can take place.' Commercial units and their associated Dower suoolies often cost $500 to 51.000. The s i m ~ l eliouid samole soinner in ~ i e u r ;1 was b&t for less than 525. Thebase was . rnnrhu&z,ut #,fa pircc
