Summary
The 875 KF Gas Analyzer is a tiamo™-controlled system for determining the water content in gases and liquefied gases. The analyzer module consists of a pipe system including four software-controlled magnetic valves, which allow the control of the sample gas and the rinsing gas flow. Additionally, an oven, a mass flow controller, the titration vessel with indicator and generator electrode (with diaphragm), and a coulometer are included in the module.
This document provides general information on the 875 KF Gas Analyzer and on water determinations in gases. Additionally, it includes useful data that show the stability of hard- and software, the robustness of the system, and the good repeatability.
Definitions and abbreviations
g/l
gaseous/liquid LPG
Liquefied Petroleum Gas is a flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles. The vapor pressure at room temperature is approx. 0.8 MPa. MFC
Mass Flow Controller Mass flow [g/L]
The mass flow is calculated using the gravimetrically determined calibration factor (L/g) and the measured sample volume. PCV
Precision Control Valve Volume flow [L/min]
The volume flow is determined with the MFC. As the MFC is calibrated to nitrogen, the value does not correspond to the real sample volume.
Sample
Unless otherwise noted, LPG was used as sample.
