Anatel A643a Analyzer Features
Anatel A643a TOC Analyzers offer several unique advantages in the monitoring of ultrapure
water systems:
Calibration and
Validation The Anatel A643a Analyzer can be calibrated with from one to three
TOC standards using Anatel’s pre-packaged Calibration Standards.
Calibration and instrument performance can be validated on-line using
Anatel’s Validation Kit.
USP Compliance for
Conductivity and
System Suitability The Anatel A643a’s limit response and response efficiency are
calculated on-line automatically to determine compliance with USP
TOC Method <643>. Meter accuracy and cell constant also can be
verified on-line to comply with USP Conductivity Method <645>.
Hot Water
Application The Anatel A643a is fully compatible with water temperatures up to
65 °C. For water temperatures from 65 °C to 95 °C, a heat exchanger
is required. The only wetted part in the Anatel Heat Exchanger is 316
stainless steel tubing.
