PRODUCT INFORMATION
Milli-Q Synthesis/Synthesis A10 12
A10 TOC MONITOR
WHAT DOES THE A10 DO?
The A10 TOC Monitor (called A10 in this manual) is used to measure the TOC of the Milli-Q Product Water. The
A10 is located inside the Milli-Q System Cabinet. Any Milli-Q system with an A10 inside will have ‘A10’
on the end of the name of the Milli-Q (i.e. Milli-Q Synthesis A10 vs. Milli-Q Synthesis).
An A10 TOC measurement is initiated every time the Milli-Q is brought from PRE OPERATE to PRODUCT Mode
(when the POU Dispenser Trigger is brought forward). A single TOC Measurement will take approximately
5 minutes. It is possible to have a TOC analysis time of either 9 or 12 minutes when the TOC levels are high. The
A10 will continuously perform TOC measurements while the Milli-Q is in PRODUCT Mode. The A10 will perform a
TOC measurement once per hour while the Milli-Q is in PRE OPERATE Mode. The A10 will not perform any TOC
measurements when the Milli-Q is in STANDBY Mode.
WHAT MAINTENANCE IS INVOLVED WITH THE A10?
The A10 uses a small UV light during its TOC Analysis Mode. The A10 UV Lamp needs to be replaced
periodically. The normal useful lifetime of the A10 UV Lamp is 1 year. The Milli-Q system uses a calendar day
timer to record the age of the A10 UV Lamp. A service message is prompted after 365 Days
(“EXCHANGE A10 UV”) to remind you to change the A10 UV Lamp. The Catalogue Number for the A10 UV
Lamp is ZFA10UV01.
There is a Cleaning Mode for the A10. This Cleaning Mode can be initiated with the Milli-Q software. The A10
CLEANING Mode does not use a chemical reagent of any kind. The A10 Cleaning is explained in further detail in
the Maintenance Section of this manual.
