1). Why was it important to quickly inject the vapor sample of CH2Cl2?

2). Would it be possible to detect compounds not containing a halogen, (Cl,Br) using a Beilstein detector?

3). The number of theoretical plates, N, is a measure of efficiency of a GC. Calculate the peak width, Wb, for a substance run on two different columns, with N=50.0, the other with N=5000, assuming the retention time,Tr, is 100 for both columns.

4). What effect would failure to completely fill the column with Tide have on the efficiency of separation of the GC? Why?

5). Is it possible to separate a mixture of inorganic salts using GC? Why or why not?
