Refineries are gearing up for [subpart-JA compliance](https://www.silcotek.com/hs-fs/file-861912793-pdf/docs/HowtheNewSubpartJaRegulationswillAffectYourRefinery.pdf).  Refiners must reduce SO2, NOx and other emissions significantly in major sources, including:

- Fluid Catalytic Cracking Units
- Fluid Coking Units
- Delayed Coking Units
- Fuel Gas Combustion Devices
- Flares
- Sulfur Recovery Plants

Subpart-JA mandates sulfur detection limits as low as 8ppm.  More importantly, the regulation makes reliable and robust sampling and analysis of sulfur emissions more essential than ever. 

SilcoTek® inert coatings not only achieve low[ part-per-billion sulfur detection](https://www.silcotek.com/h2s-mercury-ammonia-solutions) (ensuring near 100% sulfur response), they also vastly improve corrosion, wear and moisture resistance.

While robust system design and good maintenance practices help to ensure continued sampling system performance, the single most important contribution to achieving subpart-JA compliance is coating all sample flowpaths with inert SilcoTek® coatings.

## Coat the entire sample flowpath.

- Tubing
- Fittings
- Filters
- Probes
- Regulators
- Injectors
- Columns

SilcoTek coatings improve subpart-JA performance throughout the sample path.  Making SilcoTek® coatings the number one way to assure compliance.
