Evolution and innovations in ICP-MS Spectroscopy

Inductively Coupled Plasma- Mass Spectroscopy (ICP-MS) is the optimum choice when you have to carry out ultra-trace level determinations of metals and other elements. The obvious reason is that it offers innumerable advantages over the other popular technique Atomic Absorption Spectroscopy.

ICP-MS systems are manufactured by several reputed manufacturers such as Perkin Elmer, Agilent, Shimadzu, Analytik Jena, Teledyne Leeman Labs, Spectro Analytical Instruments, etc. Each manufacturer offers hardware and software capabilities that add to ease of operation. However, the common features of all makes are:

• 

  Ability to analyze the majority of elements of the periodic table.

• Simultaneous analysis of elements present in any sample.
• 大型线性动态测量范围（某些元素PPP甚至PPQ）。，即10⁸to 10¹²orders of magnitude..
• Simultaneous analysis of elements present in the sample
• 在其群体基础上，有助于确定存在的同位素的定量比的因素同位素
• User-friendly set-up and control of the instrument

The advantages offered to make ICP-MS a popular technique with a wide应用范围。本文的目标是覆盖briefly the evolution and major innovations of the technique.

Evolution of ICP-MS

Mass spectroscopy was primarily used for analysis of organic molecules. Plasma sources were known for over a century but hyphenation with ICP is relatively recent. Just over three decades have passed since the first commercial system was introduced. .ICP-MS enabled coverage of the majority of elements of the periodic table some of which especially non-metals, could not be analyzed by AAS.

等离子体还称为第四物质状态包括离子和电子在狭窄的空间区中能够大致移动。随机能量运动导致非常高的温度，导致样品原子的激发，反过来帮助发出其特征频率。在1960年代，在20世纪60年被利用了激发热等离子体的潜在应用，以激发元件。MDX SCIEX在匹兹堡会议上介绍了1983年第一个商业ICP-MS系统的Elan 250。这可以分析周期表的已知元素的90％以上。多年来，制造商的连续模型中融入了几个创新，这导致了多功能性和易于操作。的简介Dual view plasma source and laser ablationdeserves special mention as these innovations helped optimize the source viewing for improved sensitivity and analysis oh higher concentrations without the need for serial dilutions and for studying the spatial elemental composition of solid surfaces in diverse sample matrices.

The available options and innovations have contributed significantly to ICP-MS retaining its high ranking position among techniques for ultra-trace level determinations in diverse sample matrices.
