Draw a block diagram of a GC instrument, labeling all the important components. - Mobile phase 
reservoir ---> Sample injector (micro syringe) ---> Stationary Phase (column) ---> Detector (thermal 
conductor) ----> Read-out (computer) 
In a GC experiment, a student injects 2.0 μL of a 20% ethanol/water solution into the GC. Calculate the 
weight of ethanol that has been injected. (The density of ethanol is 0.789 g/mL at 20° C.) - 0.789 
g/ml -> 0.789 mg/μL 
20% of 2.0 = 0.4
