Pharma and CheckPoint
e
Portable/On-Line TOC Sensors from SUEZ
are high-sensitivity sensors used to measure the concentration of total organic carbon (TOC) in
water. The CheckPoint Pharma uses stainless steel sample inlet tubing, enabling high-
temperature and o-zone compatibility specific to Pharmaceutical industry applications. The
CheckPoint
e
is designed with PEEK sample inlet tubing that produces greater sensitivity pertinent
to the Semiconductor, Power, and other industry applications (that do not require high-temperature
or o-zone compatibility).
The Sensors are based on the oxidation of organic compounds using UV radiation. The
instruments measure the difference in conductivity before and after oxidation of the sample.
The CheckPoint Pharma and CheckPoint
e
Sensors are easy to operate, with extremely low
maintenance, and require no special training or chemical knowledge. The Sensors are calibrated
at the factory, and calibration remains stable for approximately six months. Calibration can be
performed easily at installation sites with the optional CheckPoint Vial Sampling Kit.
This manual describes typical operational requirements and recommended procedures that are
valid for most applications, and that apply to both the CheckPoint Pharma and CheckPoint
e
Portable/On-line TOC Sensors (which, for the remainder of this manual will referenced as
CheckPoint Sensors). Instructions specific to one model or another are noted as such
(CheckPoint Pharma or CheckPoint
e
, as applicable). Special conditions in operating environments
may require modifications to the recommendations in this manual. Contact Technical Support or
your local service provider.
