高壓消解罐說明:
高壓消解罐,也稱為水熱合成釜、壓力溶彈、消化罐。在烘箱中使用,是利用罐體內強酸或強堿的高溫高壓密閉的環(huán)境來達到快速消解難溶物質的目的,是分析工作中測定微量元素及痕量元素時消解樣品的得力助手。
高壓消解法被我國有關部門認定為標準方法,比如GB/T5009、GB/T6609、GB/T11914、SN/T2004.1、2—2005等。美國AOAC亦規(guī)定此法為測定As、Cd、Hg、Pb、等元素的樣品標準分解方法。
使用溫度可以達到200℃。
高壓消解罐特點:
1安全。
2消解效率高,能力強,能消解許多傳統(tǒng)方法難以消解的樣品,適應面廣。
3消耗酸溶劑少,空白值低。
4提高分析的準確度和精密度,降低了工作強度和對環(huán)境的污染。
5成本低,使用簡便。
High pressure digestion tank:
Digestion high-pressure tank, also known as hydrothermal synthesis reactor, pressure melting shells, can digest. The use of the oven, the body can make use of strong acid or alkali the confined environment of high temperaturehigh pressure to achieve quick resolution of insoluble material is designed to analyze the determination of trace elementstrace elements in the sample digestion when the right-hand man.
China''s high-resolution method was concerned that the standard methods, such as GB/T5009, GB/T6609, GB/T11914, SN/T2004.1 ,2-2005,so on. AOAC U.S. law also provides for the determination of As, Cd, Hg, Pb,other elements of the standard sample decomposition method.
The use of temperature can reach 200 ℃.
High pressure digestion tank features:
1 security.
Resolution 2 high efficiency, ability, to many of the traditional methods of digestion of the sample digestion difficult to adapt to a wide range.
3 acid consumption of less solvent, low-value blank.
4 analysis to improve the accuracyprecision, reducing the intensity of the workenvironmental pollution.
5 low-cost, easy to use
