Before using an elemental analyzer to determine unknown substances, it must undergo reliable calibration.

Our organic analysis standards are carefully selected stable substances with long-term stability, which are not easily affected by the surrounding environment. These reference materials are easy to burn, so their given carbon, hydrogen, nitrogen, oxygen, sulfur, and other element contents can be used to confidently calibrate your elemental analyzer, ion chromatography, and titrator. They can serve as certification standards for daily measurements and can be traced back to internationally recognized standard systems.
