Cleaning
This instrument supports two cleaning functions: deionized
water cleaning and deep cleaning of cleaning solution.
Deionized water cleaning function is simply called as the
cleaning in the instrument menu and this Manual. It uses the
deionized water to clean the tubeline system of the entire
instrument, including the reaction cell, measuring cell, buffer
ring, etc. The necessary cleaning function has been
integrated into the analysis process of the instrument, and
what can be used by the user is the function of manual
cleaning. The occasions requiring the manual cleaning
include: multiple manual cleaning operations are required
before the instrument is ready for a long-term shutdown, and
multiple manual cleaning operations are required before the
