Process Control has performed chemical surface treatment since 2000. This process eliminates surface adsorption of active compounds on most metals, glass, ceramic and carbon surfaces. All polar molecules such as H2S, RSH (mercaptans), H2O, O2 and others, will be adsorbed heavily to non-treated surfaces. The absorbance of molecules to the tube wall will cause long delays before the analyzer readings stabilize. Also changes in concentration takes long time. The reason is that ab/de-sorption of molecules from the metal is slow.
Treated surface has very short retention time and give therefore faster and correct analyzer results. This has also been tested and verified by Process Control As one of few companies, Process Control has now developed a procedure for Multi-Phobic treatment of metal surfaces. In a way, this is an improvement of the methods previously used. Most metals and alloys can be treated by this method. With this procedure the new chemical reacts with the metal atoms. Strong covalent bonds are created, and this “new” surface gives it both oleo-phobic and hydro-phobic properties. The surface will now repel both polar and un-polar molecules. Since the chemical bonding does not create a layer on top of the surface which can crack, the bending radius of tubing is not affected at all. Some of our competitors use coating which requires very large bending radius. The chemical treatment can be performed both on individual parts and tubing (inside as well as outside), but also directly on new or present installations. Since the treatment also involves a thoroughly inside chemical cleaning, (eg. of analytical systems) new installations can be proved «clean» before start up. Contamination of new tubing and tubing during installation is common and can be eliminated by this chemical treatment. Please note that Electro Polishing treatment is not at all the same as this treatment. Electro Polishing (EP) treatment makes the surface smoother and more corrosion resistant but has no effect on adsorption/absorption of molecules.
