General Information:

"ISO/IEC 17025 and ISO 17034 Heavy Mineral Oil Sulfur Certified Reference Material (CRM) Kit, ASTM D4294, Calibration Set B intended to be used for calibration or verification of measuring equipment, method validation, method verification, or other quality control processes applicable for analysing sulfur content in petroleum products, typically used in, but not limited to test method ASTM D4294 or other applicable mehods. The sulfur calibration kit includes 0.1000 % (1000 mg/kg), 0.2500 % (2500 mg/kg), 0.5000 % (5000 mg/kg), 1.0000 % (10000 mg/kg).
Each Sulfur CRM provides traceability of measurement to recognised national standards, and to units of measurement realised at the National Physics Laboratory (NPL) or other recognised 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.
