使用微波消解技术 ,在食品加热、加压下 ,用硝酸和过氧化氢分解试样 ,由于酸的氧化及活性增加 ,可使食品在较短的时间 (一般 6～ 8分钟 )内被消解。其消解后的样品检测限 ,回收率及精密度均符合对食品中金属离子的检测要求。1 微波消解原理微波是波长在 1米以下 (频率在 30 0
Using microwave digestion technology, the sample is decomposed with nitric acid and hydrogen peroxide under the condition of food heating and pressurization. Due to the oxidation and activity of the acid, the food can be digested in a short time (usually 6 to 8 minutes). After digestion of the sample detection limit, recovery and precision are in line with the detection of metal ions in food requirements. A microwave digestion principle Microwave wavelength is below 1 meter (frequency at 30 0
