General Information:

ISO/IEC 17025 and ISO 17034 Diesel (Synthetic) Sulfur Certified Reference Material (CRM) intended to be used for calibration or verification of measuring equipment, method validation, method verification, or other quality control processes applicable for analyzing sulfur content in petroleum products, typically used in, but not limited to test methods ASTM D2622, ASTM D4294, ASTM D7039, ASTM D7212, ASTM D7220, IP 336, IP 496, IP 497, ISO 8754, or other applicable methods.
Each Sulfur CRM provides traceability of measurement to recognized national standards, and to units of measurement realized at the National Physics Laboratory (NPL) or other recognized national standards laboratories. All sulfur content values are traceable to National Institute Standards and Technology (NIST), and each CRM provides accurate levels of uncertainty, ensuring maximum accuracy of data at hand.
ARO's Sulfur CRMs are available in 100 mL volume glass containers with tamper-evident packaging, providing assurance of sample integrity. ARO also offers set sulfur kits for each matrix and the appropriate test methods associated, providing easy and efficient procurement solutions for end-users.
