Tailpipe emissions test

Recent revelations about diesel emissions highlight SilcoTek's contribution to improving exhaust emission testing.  How do regulatory agencies detect low level NOx and sulfur emissions?  Advances in instrumentation and test procedures help, but inert surfaces like SilcoNert® 2000 and Dursan® enable testing agencies to repeatably detect part-per-million and part-per-billion levels of NOx and sulfurs.

The California Energy Commission conducted a study comparing SilcoNert® (noted as Silcosteel® in the study) to other materials commonly used in sampling systems.  The results show the SilcoNert surface prevents surface reactivity with NOx, sulfurs and other common auto emissions.

Here's an example of how SilcoNert® improves emission testing sensitivity.  Flow a 50 ppm sulfur sample through an 1/8in tube, results indicate near zero sulfur at the outlet for up to 90 minutes. 

 SilcoNert coated tube shows no delay in testing

Now coat the tube with SilcoNert® and test.  Results show all the sulfur is transferred through the tube and onto the detector within seconds; making sulfur testing of exhaust, stack and flares accurate and reliable.
