为了满足ICP、ICP-MS极低的检测限需求提供实验室级超纯酸蒸馏装置，该装置采用调压器加热，使酸保持亚沸腾状态，再将其酸蒸气冷却的原理制备超纯酸。

   该装置所用的容器均采用F4（聚四氟乙烯）和F46（聚全氟乙丙烯）耐腐蚀高纯氟塑料，因此可以处理硝酸、盐酸、氢氟酸等实验室的常用酸而不腐蚀,而这一特性不为石英亚沸腾蒸馏器所具有。

   实验证明，将大部分金属杂质含量约10ppb的酸提纯，经过一次蒸馏后，金属杂质含量可以降低到1ppb左右，甚至更低。若对酸要求更高，可增加提纯次数。

配件：FEP窄口瓶、调压器、F4接头、加热套、塑料水池、进出水管

   高纯氟塑料亚沸腾蒸馏器特点：

   亚沸蒸馏器是制备高纯试剂和高纯水的氟塑料仪器，它具有技术先进，结构合理，安装简单，操作方便，维修简便。亚沸蒸馏是利用加热套热辐射原理，保持液体温度低于沸点温度蒸发冷凝从而制备高纯水和高纯试剂，在进行测定（原子吸收光谱、气相色谱、同位素、电感藉合等离子发射光谱等）痕量元素及微量有机物时，是不可或缺的配套仪器设备。

acid purification

To meet the ICP, ICP-MS detection limit needs of low-level laboratory ultrapure acid distillation unit, the device uses voltage regulator heat to maintain a sub-boiling acid, and then the acid vapor cooling of the principle of ultra-pure acid preparation .
   The device used in containers are used F4 (PTFE) and F46 (poly FEP) corrosion-resistant high-purity fluorine plastic, so you can deal with nitric acid, hydrochloric acid, hydrofluoric acid and other commonly used laboratory instead of corrosive acid, and this feature is not the quartz sub-boiling stills have.
   Experimental results show that the majority of metal impurities in some 10PPB acid purification, after a distillation, the metal impurities can be reduced to 1PPB, or lower. If acid requirements are higher, increase the number of purification.
   Accessories include: FEP narrow mouth bottle, regulator, F4 joints, heating cover, plastic tank, and out of water
