Sulfur is supplied as a certified reference material (CRM) prepared at a nominal concentration of 1 g/L sulfur (S) in water. This single-component calibration standard is designed for elemental analysis using inductively coupled plasma (ICP) techniques.

Sulfur ICP standards are used in analytical laboratories for instrument calibration, analytical method validation, and routine quality control when determining sulfur concentrations in environmental samples, industrial materials, and pharmaceutical products. Laboratories performing elemental analysis rely on certified standards to verify instrument performance and maintain measurement accuracy in ICP-based analytical methods.

This TraceCERT® certified reference material is produced in accordance with ISO 17034 and characterized according to ISO/IEC 17025. The material is traceable to SI units and measured against primary reference materials from National Metrology Institutes (NMI), including NIST.

Sulfur ICP standards are commonly used in environmental laboratories, industrial quality control laboratories, pharmaceutical testing laboratories, and academic research facilities performing elemental analysis by ICP techniques.

This certified reference material is supplied with a certificate of analysis providing traceable concentration values suitable for calibration, method validation, and analytical quality control.

Shipping and Storage Notice

Please note that shipping and long-term storage conditions for certified reference materials may differ. Manufacturers determine the most appropriate shipping method based on product stability and shipping data. Some CRM standards may ship at ambient temperature even though recommended long-term storage conditions are refrigerated or frozen. This does not affect product integrity when handled according to manufacturer documentation.
