Paramagnetic O2 / Oxygen Analyzer

This utilizes the fact that Oxygen is a paramagnetic gas which distinguishes oxygen from other gases because it is attracted into a strong magnetic field. Basically when a gas sample is introduce to the instrument the oxygen will be drawn into the magnetic field resulting in a change in the flow rate. The flow rate change is proportional… Read More »

Zirconia O2 Measurment Principle

There are two different types of Zirconia measurement systems. 1      amperometric 2      potentiometric Figure shows a schematic of the amperometric system. An amperometric sensor consists of  zirconia cell that has a high voltage being applied across the two platinum electrodes. Oxygen then flows through  the diffusion hole and comes into contact with the cathode… Read More »

What is Steam Traps ?

Steam trap is a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. If condensate is not drained immediately or trapped from the system, it reduces operating efficiency by slowing the heat transfer process and can cause physical damage through the phenomenon known… Read More »


The Py-Gas is an online sample conditionerdesigned for difficult sample conditioning situations such as the following. • Hot and dirty gases • Pyrolysis gases • Liquid mists or water removal • Wet, dirty gases • Heavy particulate removal • Fine carbon removal The initial sample problem addressed by the Py-Gas was in gas/liquid feedstock for a… Read More »
