刀式混合研磨仪GM200在样品制备中的应用研究
目的 建立蔬菜、水果、鱼类、肉类及粮食谷物类等样品前处理操作规范。方法 采用前处理设备德国莱驰刀式混合研磨仪(RETSCH GRINDOMIX GM200), 从各类食品样品着手, 上机进行反复试验, 找到最适的仪器操作参数对样品进行均一化处理。 结果 蔬菜、水果、鱼类、肉类及粮食谷物等经刀式混合研磨仪GM200研磨后均获得均一性样品, 满足后续检测的实验要求(包括元素、农残、兽残等检测项目)。结论 采用刀式研磨仪GM200对样品进行预处理, 可以进一步地提高样品的均一化程度, 更好地保留分析目标化合物, 为食品样品中待测组分的提取、净化、浓缩, 进行定量、定性分析检测做好充分准备, 保证结果的准确性和重现性。
Objective To establish the pre-processing operation specification for vegetables, fruits, fish, meat and grain. Methods Using the pretreatment equipment (RETSCH GRINDOMIX GM200), all kinds of food samples were tested repeatedly to confirm the most suitable instrument operation parameters on the ho-mogenization processing samples. Results Vegetables, fruits, fish, meat and grains homogeneity samples were obtained after GM200 grinding, which could meet the requirement of the follow-up testing experiments (including detection of elements, pesticide residues and drug residues). Conclusion The samples being pre-treated using RETSCH GRINDOMIX GM200 can further improve sample homogenization and retain the target compounds preferably to be prepared for extraction, purification, concentration, quantitative and qualitative analysis of food samples, in order to ensure the accuracy and reproducibility of the result.
