Very good presentation!!Well done!! I have one question! Why are we using different cuvettes for UV range under 200 nm? And where can I learn more about them?
Plastic cuvettes absorb wavelengths below 270 nm. Most glass cells have a cut-off around 220 nm. The material itself absorbs the light. If you want to observe below 220 you will need quartz cuvettes. If you want to observe below 200 you will need very expensive quartz cuvettes. Here is one place to look for some info... www.ssi.shimadzu.com/products/uv-vis-spectrophotometers/faqs/cuvettes.html
Excellent presentation, excellente content, excellent explanation, Now I understand everything about UV vis spectroscopy thanks to you
very informative
