Basic Nitriding Sampling System – Hydrogen Analyzer
Super Systems Inc. Page 4 of 12
Introduction
This instrument uses the measurement of Hydrogen to display % Hydrogen (H
2
), % Dissociation (DA), and
% Ammonia (NH
3
). When the flow rates of Nitrogen, Ammonia, and Dissociated Ammonia are manually
entered, the instrument can also calculate Nitriding Potential (K
N
).
