VA purgemeters with surface passivation for trace-level analysis
Product News Monday, May 23, 2016: KROHNE Pty Ltd
Duisburg, April 5, 2016: For its variable area flow meters DK 32, DK 34 and DK 37, KROHNE now offers the option of surface passivation for trace-level analysis.
Trace-level analysis is used for providing evidence of very small concentrations in the range of ppm (parts per million) to ppb (parts per billion). Here, it is very important that none of the particles to be detected are already adsorbed in the sample feed line as this would lead to a delayed or even wrong analysis result. Examples are the measurement of H2S content in natural gas or oil, mercury, or NOx/SOx flue gas analysis in various industries.
To avoid adsorption, sample feed lines, fittings and valves can be surface passivated. This can now also be applied to the DK 32, DK 34 and DK 37 all-metal purgemeters that are used for adjustment and monitoring of the sample flow to the analyser.
Before being assembled and calibrated, all metal components in contact with the medium such as cone, float, valve components, etc., receive a SilcoNert 2000 inert silicon coating, a patented surface treatment at a temperature of 400°C / 752°F. The same is possible for wetted metal components of DK 46, DK 47, DK 48 and DK 800 glass devices.
SilcoNert 2000 is a registered trademark of SilcoTek.
