The resulting spectrum received from the spec is shown:

Here is an example of what is a good read out from the Quail lab.

The concentration is found by this formula:

[math]\displaystyle{ C(mM)=\frac{A_{680}}{37.9}*\begin{cases} 100 (for 1:100) \\ 1000 (for 1:1000) \end{cases} }[/math]

We didn't trust the pathlength correction given to us by this spec so we ran the 1:100 and 1:1000 dilutions in the Stephanopolous lab, and here are the results that we got:

1:100 - A₆₈₀ = 1.208
1:1000 - A₆₈₀ = .425

After completing the calculation with the 1:1000 dilution, we got a concentration of 11.21372 mM, and we have a 4.5 mL solution.
