Cleaning

Waste solution tube

Liquid leak sensor

Drain tray
Visually check that liquid is not leaking through any tube.
The flow path should be washed on a periodic basis. Bubbles
will be formed if the flow path between the syringe and needle is
contaminated; these bubbles will adversely affect the analytical
reproducibility of the system.
(1) When using an aqueous detergent
At the end of measurement, wash the flow path with distilled
water. If contamination is heavy, fill the syringe with
detergent and leave it overnight. After cleaning the syringe,
rinse it with distilled water. If the instrument will not be
used for a week or loner, wash the flow path adequately
with distilled water and keep the syringe filled with distilled
water. In particular, the syringe and sample loop should be
washed carefully to remove contaminants. And prevent the
inside of flow path from drying out. If the flow path dries
out though contaminated, decontamination may become
impossible.
