Parts per billion (ppb).
A term used to report trace chemical analyses. It refers to the
concentration of the element or compound present within one billion parts of water. One
microgram per liter (µg/L) is equal to 1 ppb).
Resistivity.
Resistance, measured in megohmcentimeters (M
Ω
-cm), to the flow of electrical
current through high-purity water. Resistivity is a means of continuously measuring the
purity of the water and is the reciprocal of conductivity.
Temperature compensation.
Conductivity and resistivity measurements normalized to
25 °C (77 °F) for reporting purposes. Normalized conductivity and resistivity
measurements reflect the values that would be reported at a sample temperature of 25 °C
(77 °F) using a model based on sodium chloride in water. Conductivity and resistivity of
electric current in water depend on the temperature of the water. The lower the
temperature, the lower the conductivity and the higher the resistivity.
Total organic carbon (TOC).
A measurement of the organics present in water based on its
carbon content. In high-purity water, TOC is measured in parts per billion (ppb). Total
organic carbon is used interchangeably with total oxidizable carbon.
