6.9 Preparing System for End-of-Run Cleaning

System cleaning is an automatic feature that occurs upon completion of each method run
and is required to prevent cross-contamination between runs and to maintain the system in
optimum condition. The two sample inlet lines and the fraction line valve (all eight fraction
lines) are cleaned as part of the end-of-run cleaning process. The pump seals are also
washed as the final step in this process and the internal system lines are stored with 20%
ethanol from buffer position 8 (Figure 6.38).
