Inert Coatings for Substantially Improving Analytical Accuracy

Measuring trace (ppm or lower) sulphur, mercury, and other emissions is both required by law and critical to productivity. SilcoNert- and Dursan- coated instruments from SilcoTek (USA) produce virtually instant readings with superior accuracy because critical compounds don’t get adsorbed by stainless steel sample transfer equipment, an inevitable consequence of untreated metal.

Even electropolished flow paths take well over an hour to produce a signal without inert coatings. With them, analysts can start to see results within seconds of injecting the sample. This saves tremendous costs in the form of higher daily sample throughput, less labour, and compliance to environmental regulations.

The benefits of inert coatings aren’t just limited to better instrument performance. Collecting samples off-site once entailed a frantic race to the lab to test them before important molecules were scavenged by the metal sample storage vessels. With SilcoNert- and Dursan- coated sampling equipment, trace-level samples can be adequately maintained for as long as 2 weeks without loss.

Dursan-coated sample cylinders retain almost 100% of H2S samples after 3 days. Uncoated cylinders consume nearly the entire sample within one day.

SilcoTek coatings offer the chemical resistance/inertness of PTFE but dramatically improved durability, temperature resistance, and adhesion. A SilcoTek coating can be used at 450° C and sometimes greater, whereas PTFE is destroyed above 230° C. SilcoTek’s innovative chemical vapour-deposited (CVD) treatments are bound molecularly to the substrate so they won’t flake, even on tubing that is bent or flexed.

Trust SilcoNert and Dursan coatings for any analytical application: Improve instrument performance and analytical accuracy, Fight corrosion, Reduce the impact of moisture in samples.
