Precipitation Gravimetry01:03

Precipitation Gravimetry

5.3K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Area of Science:

  • Analytical Chemistry
  • Food Science
  • Metrology

Background:

  • White granulated sugar is a vital commodity across multiple industries.
  • A certified reference material (CRM) is essential for ensuring sugar safety and quality.
  • Key quality indicators include colorimetric value, ash, sucrose, and reducing sugar content.

Purpose of the Study:

  • To develop a certified reference material (CRM) for grade one white granulated sugar.
  • To comprehensively assess the homogeneity and stability of the CRM.
  • To determine the CRM's designated property values and associated uncertainties.

Main Methods:

  • Collaborative certification involving 11 laboratories.
  • Assessment of homogeneity and stability.
  • Determination of property values and uncertainties for key sugar quality parameters.

Main Results:

  • The CRM demonstrated sufficient homogeneity within and between bottles.
  • The material remained stable for up to 20 months.
  • Designated property values with expanded uncertainties were established for colorimetric value, conductivity ash, sucrose, and reducing sugar content.

Conclusions:

  • The developed sugar CRM is homogeneous and stable, providing reliable measurements.
  • This CRM supports method validation, quality control, and metrological traceability in the sugar and food sectors.
