As you can see in the picture, the instrument uses a Xe source. Given that the instrument is capable of measuring from 200-800nm, if Xe was not used, what other source(s) could be used? Refer to figure 7-3.
How many monochrometers does this instrument have? Why?
Trace the light as it goes from the Xenon lamp all the way to the circle just slightly to the right and a little bit down from S4. What do you think that circle is? In class we talked about many types of these, which kind do you think this one is for a fluorimeter? Why? Explain.
What is/are some strategy(ies) that this instrument has for dealing with noise that you see present in the optics diagram?
Why does a fluorescence cuvette have to be clear on four sides?

Ru-2 is weakly luminescent due to the effective photoinduced electron transfer (PET) from Ru(II) luminophore to electron acceptor, 2,4-dinitrobenzene-sulfonyl (DNBS). In the presence of biothiols, such as glutathione (GSH), cysteine (Cys), and homocysteine (Hcy), the emission of Ru-2 solution was switched ON, as a result of the cleavage of quencher to form the product, Ru-1. Ru-2 showed high selectivity and sensitivity for the detection of biothiols under physiological conditions, with detection limits of 62 nM, 146 nM, and 115 nM for GSH, Cys, and Hcy, respectively. The emission lifetimes of Ru-1 and Ru-2 were measured to be 405 and 474 ns,…arrow_forward
