B.1 Performance Specifications
The Anatel A643a TOC Analyzer is specifically designed for use in applications that monitor
ultrapure water with a typical conductivity less than 0.2 microsiemens/cm (as high as 5.0 µS/
cm for pH neutral waters) compensated to 25 °C.
At a minimum, the Anatel A643a System consists of a single Analyzer and a C80 Controller.
The maximum configuration may contain up to 8 Analyzers and 8 Controllers in addition to a
host computer and associated input/output devices.
Note:
Anatel A643a Specifications are subject to change without notice.
PERFORMANCE
Note:
† Repeatability of reading on an individual instrument.
** Sample water temperature specification stated without external heat exhanger. For sample
water over 65 °C a CX-20 heat exchanger is highly recommended.
