高压消解罐，也称为溶样器、压力溶弹、水热合成反应釜、消化罐、聚四氟乙烯高压罐。
工作原理：
利用罐体内强酸或强碱且高温高压密闭的环境来达到快速消解难溶物质的目的，是测定微量元素及痕量元素时消解样品的得力助手。样品前处理消解重金属、农残、食品、淤泥、稀土、水产品、有机物等。
Use of tank body strong acid or alkali environment and high temperature and pressure sealed to achieve the purpose of rapid digestion of insoluble material, was to determine the trace elements and trace elements in the right-hand man during digestion. Sample digestion and heavy metals, pesticide residues, food, mud, earth, fish, organic, etc..
烘箱中使用温度可以达到200℃，压力5Mpa。
高压消解罐特点：
1安全。设计时，被动控温转为主动控压。即使温度失控，也不会有危险。
2消解效率高，能力强，能消解许多传统方法难以消解的样品，适应面广。
3密封性好，内杯凹凸榫槽设计。
4内杯元素空白值低，提高分析的准确度和精密度，降低了工作强度和对环境的污染。
5.外罐内杯有相应编号，方便实验。
6.成本低，使用简便。前期后期投入都很少，操作容易，操作人员使用前几乎不需要培训，维护简单。
7.30ml及以下规格可定制成PFA内杯，耐温，承压，耐变形，耐渗透更优
Digestion tank features:
1 security. Design, passive temperature control to active control of pressure. Even if the temperature is out of control, there will not be dangerous.
2 digestion efficiency, ability, will counteract many of the traditional methods are difficult to sample digestion, wide adaptation.
3, sealing, embossing tongue and groove design within the cup.
4 cup of elements within the low blank value, improve the analysis accuracy and precision, and lower working strength and environmental pollution.
5. External tank Cup corresponding number, to facilitate experiments.
6. Low cost, easy to use. Early post-investment are very few, easy, almost no operator training before use, and simple maintenance.
7.30ml and the following specifications can be customized into a PFA within the cup, temperature, pressure, resistance to deformation, better resistance to penetration

高压消解法被我国有关部门认定为标准方法,比如GB/T5009、GB/T14962、GB/T6609、GB/T11914、GB/T17378、SN/T2004.1、2—2005、SN/T 1634-2005等。美国AOAC亦规定此法为测定As、Cd、Hg、Pb、Se、Zn等元素的样品标准分解方法。
