Maintenance 119
ISE Detergent Solution is automatically run through the ISE module as part of the
shutdown wash procedure (WASH2). Manually perform additional ISE washes
(described in the following procedure) more frequently, but do not exceed 3 times in 24
hours in the following circumstances:
• Dialysis samples are run routinely
• Veterinary samples are run routinely
• The system is in use more than 8 hours a day in a high volume laboratory, which is
having persistent imprecision or Chloride bias issues that have not been resolved by
any other means
NOTE: Do not perform the ISE electrode wash more than 3 times per day (once as part of
the shutdown wash and twice on a per-shift basis). Pour fresh ISE Detergent into a cup,
not a tube, before each wash, from the CTT.
