Anatel Operator Manual
1.10 Symbols and marks
The PAT700 Total Organic Carbon Analyzer complies with those parts of 21 CFR, Part 11
concerning the collection, retention, access and retrieval of data as electronic records. The
instrument uses no electronic signature(s), thus those parts of the rule referring to electronic
signature(s) are not applicable. Extensively documented and verifiable tests have been
conducted to establish 21 CFR, Part 11 compliance.
The PAT700 Total Organic Carbon Analyzer is comprised of a line of precision instruments
which meet or exceed the following international requirements and standards of compliance:

1.12 Definitions of terms
The following terms are used throughout this manual:
Conductivity. A measure of the ability to conduct current through water. Conductivity, very
low with high-purity deionized water, is the reciprocal of resistivity and is measured in
microsiemens per centimeter (μS/cm).
Megohm (M). A measurement of 1,000,000 ohms.
Microsiemens (μS). A unit of conductance in the metric system equivalent to one millionth of
an ampere per volt (1 µS = 1 x 10
-6
A/V).
Normalize. To make conform to a standard. In this case, the user performs calculations on
the raw data to produce a result in a standard unit of measure.
Organic. A molecule that contains carbon but excludes carbonate CO
2
, CO, CS
2
, or cyanide-
related compounds. Oxygen is very common in organics, and they almost always include
hydrogen.
Oxidation. The loss of electrons by a chemical species, typically with oxygen. Organic
carbon, for example, oxidizes to carbon dioxide and water.
