Steam distillation instrument at GB500926-2016 - Determination of nitrosamine compounds in food.
at GB500926-2016 In the determination of nitrosamine compounds in food, steam distillation instrument is an important instrument. This method is based on steam distillation and liquid-liquid extraction technology, which can effectively separate and enrich nitrosamine compounds in food. Steam distillation instrument plays a vital role in the experimental process, and its performance directly affects the accuracy and reliability of experimental results.
The steam distillation instrument works by means of heating and pressurizing to distill the nitrosamine compounds in the sample along with the water vapor. Then, the distilled nitrosamine compounds were extracted from the water vapor and enriched into the organic solvent by liquid-liquid extraction technology. Finally, the qualitative and quantitative analysis of nitrosamine compounds in organic solvents was performed.
When using a steam distillation instrument, special attention needs to be paid to the following points: first, ensure that the sealing performance of the instrument is good, so as not to affect the experimental results due to water vapor leakage; Secondly, the heating temperature and time should be controlled to avoid excessive heating and decomposition of the sample; Finally, it is necessary to select appropriate organic solvents for liquid-liquid extraction to ensure that nitrosamine compounds can be fully extracted.
In short, the steam distillation instrument is in GB500926-2016 It plays an important role in the determination of nitrosamine compounds in food. Through the rational use of steam distillation, nitrosamine compounds in food can be effectively separated and enriched, providing a reliable basis for food safety testing. At the same time, in order to obtain accurate experimental results, it is necessary to pay attention to the relevant operation points and precautions when using a steam distillation instrument.
