  • Page 28: Chapter 3: Maintenance

    Chapter 3 Maintenance This chapter is a basic maintenance guide for LiQuilaz II liquid particle counters. Occasional cleaning is required of the liquid capillary and it is the customer's responsibility to perform the cleaning when necessary. The need for capillary cleaning and the general health of the capillary can be improved by continuously running water through the system when not in use.

  • Page 29: Required Materials

    Chapter 3 Maintenance Required materials: • Capillary cleaning kit • A standard laboratory glassware cleaning solution Cleaning Solution When selecting an appropriate cleaning solution, consider the types of contamination that will have deposited onto the capillary from the most recent fluid sampled. For instance, if DI water was sampled last, bacteria, or particles are the most likely sources of contamination.

  • Page 30: Capillary Cleaning (Online Version, E And S Series)

    Chapter 3 Maintenance Capillary Cleaning (Online Version, E and S Series) >> To clean the capillary: 1. Turn off and unplug the particle counter. 2. Isolate the liquid particle counter from its fluid source. 3. Disconnect the sample inlet and outlet fittings. Figure 3-1 LiQuilaz II fittings 4.

  • Page 32: Applying Additional Capillary Cleaning Techniques (For S Series Only)

    Chapter 3 Maintenance Applying Additional Capillary Cleaning Techniques (for S Series only) In cases where polymers were sampled, the most likely cause of contamination is trace polymer dried to the capillary. In this case, the polymer will probably require long term soaking in the appropriate solvent to facilitate removal of the contaminant.
