Sulfur/Nitrogen Standards for Petroleum Analysis

Our sulfur/nitrogen standards have been specifically designed for petroleum analysis. The standard sulfur source is dibenzothiophene and the standard nitrogen source is pyridine. All listed standards are prepared in "ultra-pure" iso-octane. Our iso-octane is processed in our laboratory by proprietory processes to reduce residual sulfur and nitrogen to low ppb levels. Traceable to NIST test masses. Packaged in 1.5 mL aliquots in wide neck ampules under argon.
