Select one of the 3 radio buttons and name the recalculation list you are using if

appropriate.

In order to perform automated injections of a group of samples you must first

build a sample list and then a sequence list. An example of a sample list is

displayed below. This screen can be activated from the pull down menu under

File, New Sample List. You must create the list from the empty table you see on

your screen. All of the entry fields are the same as the previous information in

this section for single sample injections. Be especially sure that the AutoSampler

vial information is correct in your sample list.

Once the sample list is created, it is time to create the sequence which will cause

the injections to be made. An example is given below. Select Inject for action,

type the name of the method that you wish to run, and type the name of the

sample list you wish to be injected. When this is completed you are ready to

inject your samples. Use the begin button to start the sequence.

General Parameters that Affect EI Operation

Electron Multiplier Gain

Normal Saturn GC/MS operation assumes that the electron multiplier gain is set

up to produce approximately 10

electrons per ion. This is accomplished

automatically with Auto Tune.

The AGC software operates on information derived from the prescan

measurement of the TIC (the AGC peak).

(See Main Method Editor in the Saturn Method Manual for details of scan

function). Unlike the ionization time or filament emission current that can alter the

actual number of ions created in the ion trap, changing the electron multiplier

gain only alters the amplification of the ion current signal of ions after they are
