應用

Sucrose Optical Rotation standard reference material (SRM) is intended for use as a saccharimetry standard, used to calibrate polarimetric systems.

特點和優勢

• Accompanied with certificate documenting NIST-certified values of sucrose mass fraction and non-certified values of carbon and hydrogen mass fraction.
• Certified chemical purity values are determined using a quantitative ¹H-nuclear magnetic resonance spectroscopy (q¹H-NMR).
• Certified values are metrologically traceable to the International System of Units (SI) of mass.
• The NIST certificate is provided with storage and use instructions.

其他說明

Certified for the analytes listed below.
