a. One microliter of 0.1 μg/mL 0.1 μg/mL benzene is injected into a gas chromatograph using splitless injection. How much benzene is loaded onto the column?
b. How much benzene is loaded onto the column if split injection with a split ratio of 100:1 100:1 is used?
c. If both peak widths are 1 s, 1 s, < what is the mass of carbon entering the detector for splitless and split injection in (a) and (b)?
d. Based on the detection limits in Table 24-3, would a flame ionization detector be sensitive enough to detect the splitless and split injections?
