Onc microliter of 0.15 pg/mL benzene is injected into a gas chromatograph using splitless injection. How much benzene is loaded onto the column? mass: Pg benzene How much benzene is loaded onto the column if split injection with a split ratio of 100:1 is used? mass: Pg benzenc If both peak widths are ls, what is the mass of carbon entering the detector for splitless and split injection? 1 splitless injection: PE CA Pg Cls split injection: Based on the detection limits in Table 24-3, would a flame ionization detector be sensitive enough to detect the splitless and split injections? The split injection could be detected, but the splitless injection would be below the detection limit. Both the splitless and splitless injection could be detected. Both the splitless and splitless injection ure below the detection limit. The splitless injection could be detected, but the split injection would be below the detection limit.
