2. Calculate the purge time based on the flow rate and sample loop size. The time
must be sufficient to allow three volume changes of the autosampler. The
autosampler volume in Table 4-2
includes the inlet and outlet lines.
Ta b l e 4 - 3
lists sample purge times for the two sample loops at selected flow rates.
