I am a fresh engineering graduate with limited GC-MS experience and was instantly put into a position to decide what kind of analytical instrument our company needs, which I think a GC-MS will be most beneficial. None of my coworkers have extensive experience with GC-MS instruments, so my resources within the company are limited. But I'm here looking for advice, opinions, and ready to learn more! 
Objective: Test for the purity of liquid Halon 1301 to the accuracy of 0.01 mole %.

For just testing the purity of material you manufacture or buy can you justify the extra upfront and ongoing cost of a GC-MS over a GC?
