    The second type of automation control simply involves running a series or sequence of methods without control of an addressable device such as an AutoSampler. This is referred to as non-addressable automation. An example of non-addressable automation would be to run a series of analyses where sampling is accomplished using a gas sampling valve controlled from one of the 3800 valve drivers.
