微波溶样是近年来分析化学的一项重要进展。它结合高压消解和微波快速加热两方面性能,与传统溶样方法相比,具有样品消解快、试剂耗用少、空白低、避免挥发损失、回收完全等突出优点,还能消解许多常法难以消解的样品。适合各类分析试样的前处理,尤其适合痕量分析和超纯分析。因而在世界各国分析化学实验室中迅速得到普遍推广。 我所自1986年起就致力于高压密闭微波消解设备的研制,其中高压密闭消解罐的研制已经历了第一代,第二代,现在是第三代产品,它与我所研制的光纤压力自控微波消解炉组合成含有多项专利技术的MK型光纤压力自控密闭微波消解系统。 MK型微波消解系统具有三道安全措施:一、设计独特的光纤压力自控系统能有效地控制和反映加热过程中消解罐内部压力的即时变化,并能实现0～4MPa范围内8档压力的控制。用户可根据需要任意设定;二、安全泄压孔:加热过程中万一自控失灵,消解罐中的安全泄压孔会及时释放压力;三、安全矮裂膜:当一、二道安全措施失灵或由于操作不当出现瞬间超压现象时,爆裂膜会立刻崩裂,避免整个消解罐的爆裂。因此,MK型微波消解系统具有三保险功能,用户可以绝对放心地使用。
Microwave digestion is an important advance in analytical chemistry in recent years. Compared with the traditional solution-dissolving method, it combines the advantages of high-pressure digestion and microwave rapid heating. Compared with the traditional solution-dissolving method, the invention has the advantages of rapid sample digestion, less reagent consumption, low blank, avoiding volatilization loss and complete recovery and the like, Digested sample. Suitable for pretreatment of various analytical samples, especially for trace analysis and ultra-pure analysis. Therefore, it is widely popularized rapidly in analytical chemistry laboratories all over the world. Since 1986, we have been devoted to the research and development of high pressure closed microwave digestion equipment. The development of high pressure closed digestion tank has gone through the first generation and the second generation. Now it is the third generation product. It is compatible with the optical fiber pressure Self-controlled microwave digestion furnace combines a number of patented technology MK-type optical fiber pressure-controlled closed microwave digestion system. MK type microwave digestion system has three safety measures: First, the unique design of optical fiber pressure control system can effectively control and reflect the heating process of digestion tank internal pressure changes in real time, and can achieve 0 ~ 4MPa range of 8 files pressure control . Second, the safety pressure relief hole: heating process in case of failure of self-control, digestion tank safety relief hole in a timely manner to release the pressure; Third, the safety of the dash film: when one or two safety measures Failure or improper operation due to an instantaneous overpressure phenomenon, the rupture membrane will immediately crack, to avoid the entire digestion tank burst. Therefore, MK microwave digestion system has three insurance features, users can use it with absolute confidence.
