Question

Match the instrument detector, column or item to the most appropriate response: R-phase uses DC and RF ramp to separate ion masses N -phase pseudo stationary phase N- P detector More Polar compounds elute first FID More Polar compounds elute last TCD Universal and nondestructive electron Capture Voltage produced due to differences in electron affinity Ion Trap MS Current flow between two electrodes quadruple MS Analysis using voltage changes Electro osmotic flow Current - voltage curve MEKC Best response is to hydrocarbons Anion exchanger Uses thermionic principles Caption exchanger Can hold circulating ions up to 15 minutes voltammeter Chemical change forced by applied voltage/current potentiometer Uses sulfonic acid in stationary phase ampere meter Uses quaternary amines in stationary phase Galvanic cell Moves toward anode when wall charges are negative Electrolytic cell Best detector for hydrogenated organic compounds
