For each parameter listed, determine whether or not a change in the parameter will have an effect on the retention time of the compound. a.) Increasing the temperature of the injector the retention time as long as the sample vaporizes. b.) Increasing the temperature of the detector the retention time as long as the sample does not condense. c.) Increasing the amount of the injected sample the retention time as long as the column is not flooded. d.) Increasing the detector attenuation the retention time. e.) Increasing the length of the column the retention time. f.) Increasing the column temperature the retention time.
Options: Will increase, Will decrease, will have no effect
WILL INCREASE BECAUSE of increased retention times of the column, due to increased activity are not uncommon. In this case passivation of the column material happens.

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System Change AS O AS < 0 O AS = 0 | A few moles of helium (He) gas.

A number of factors determine the rate at which a given compound travels through a gas chromatograph. List two of these factors: The period following injection that is required for a compound to pass through the column is called the What would happen to the retention time of a compound if the following changes were made? Decrease the flow rate of the carrier gas Increase the temperature of the column Increase the length of the column How do the temperature...
