I. Summary
1. Application
)$46 Fat Analyzer, designed in accordance with GB/T 14772-2008, can
be used not only in measuring the fat content in food, diary product and
feedstuff, but also in testing the soluble organic compound in detergent,
medicine, petrochemicals, fiber products, soil and sewage etc.
For example:
(1). To test the fat content in the food, feedstuff, grain, and seed.
(2). To extract the fat from the sewage and mud.
(3). To extract the semi-volatile organic compound such as pesticide and
weedicide.
(4).To extract plasticiser from plastics; to extract colophony from the paper; to
extract grease from the leather.
(5).To perform the pre-digestion process to the solid samples for the Gas
chromatography (GC) or Liquid chromatography (LC).
2. Principle
Based on the principle of Soxhlet extraction,
)$46 uses the weighing
method to obtain the fat content. After being extracted from the sample by
solvents such as absolute ether or petroleum ether, the fat is dried and
weighed. The difference between the vessel’s weights before and after the
extraction is the fat content.
