Injection Path Cleaning (Preparative Sampler)

The Multi-wash table allows you to specify up to four steps that will be used to clean the system. The Start Cond. step is obligatory; you cannot switch it off. However, you can switch off the Needle Outer wash if it is not required.

For each cleaning step,

  • Click the Solvent down arrow and select the solvent to use (S1, S2, S3) or switch the step Off.

  • Specify a duration (in seconds) in the Time [s] field.

  • Mark the check boxes for Needle Inner (the inside of the needle),Needle Outer (the outside of the needle) and/or Draw Port to include these actions. If all three are selected, they are carried out simultaneously; if none is selected, the step is ignored (equivalent to selecting Off).

  • Add a comment in the Comment column, if necessary. The Comment is limited to 20 characters; however, the use of some special characters may reduce this limit.
