, Let’s give you the sad news first:I don’t believe that there will be any solution for your problem! – Sorry!
I even DON’T
believe that your value of: ε
= 1.0 * 10-4
L / mol can be of any true, too!
Contrary I believe that nobody is able to give you a true value for!Let’s do some calculation together:
(But do self-control too!)
Not only I have to believe that NOBODY
till jet was ever able to build a Spectrometer of such low noise, to bring your Signal significantly out of the measuring noise at all.
If you go the other way and bring your final Signal to 1.0 AU
you can easy calculate, that it would require a Cuvette with a Pathlength of nearly ONE Kilo-Meter
I think also an absolute impossibility!
You could finally use a so called “Multi-Reflection-Cuvette
” to shorten the physical Dimension, but I don’t believe you are able to find anyone with a higher Factor then 100.
But even in the case you could find one, the Noise-Problem will still survive!!
How much higher will be the Problem in case of even lower Concentration of CCl4?
I can only hope that there will be any other Solution to your Problem, but as I don’t know it in more details, no hint can be given.
I hope it may be anyway of help to you!
