　　克莱沃，2010年3月1日- SPECTRO MS在Pittcon 2010上(奥兰多/佛罗里达, 2010年2月28日-3月5日) SPECTRO展示了全球第一台完全同步测量的电感耦合等离子发射质谱仪(ICP-MS, 见背景介绍部分)。SPECTRO MS记录了从锂到铀的所有元素谱图，可用于各种金属元素分析。与连续质谱相比，使用这款仪器，用户可大大增加样本通量，而且分析准确度更高。

　　“SPECTRO MS将会不断地改善质谱仪。与几年前出现的分光仪(optical emission spectrometer)一样，SPECTRO MS可以进行同步测量的优势也将在市场上掀起一场变革，” SPECTRO公司管理主管Manfred Bergsch称。“SPECTRO MS不仅具有更高的准确度和结果重现性，且比普通质谱分析速度更快;它为实验室开拓了全新的应用前景。”

　　一系列全新设计的高端元件实现了全谱同步记录：

　　在离子传递过程中，新型的离子光学元件可有效的将离子从等离子体传输到质谱中;同时有效地消除电子束中的中性粒子和光子。

　　Mattauch-Herzog设计——双聚焦扇形场质谱仪。静电分析仪和永磁体直接将离子聚焦在焦平面上，不需要再进行离子束扫描。

　　极其强大的有4,800个通道的直接充电检测器，放置在质谱仪焦平面上，可同步记录从锂元素到铀元素的全质量谱图，平均每个同位素占20个通道。每个通道均被分为两个独立的且信号放大倍数不同的检测器。从而实现SPECTRO MS精确测定极限同位素比率的动态工作范围。

　　新发明的休眠模式，真空系统耐用、用户友好且能耗极低。

　　SPECTRO MS的外观、软件和激发技术均与ICP-OES主打产品SPECTRO ARCOS密切相关。新型仪器中的等离子体发生器为耐用、独立的27.12 MHz发生器；保证了等离子体极其稳定能量耦合。

　　研究实验室的新标准

　　新型SPECTRO MS的应用范围广泛。Bergsch说到：“我们了解到，许多应用领域，尤其是在商业研发实验室，样本数量非常大且这类机构的要求极高。这里，SPECTRO MS能够真正在以下方面显示出优势：精确、重现性、检测限、样本通量。SPECTRO MS很快就会在这一领域成为标准系统。”

　　同位素比率分析

　　除了研究实验室，同步质谱还可应用在以下工业领域：环境、化学和制药实验室，这些领域的用户可以获益于仪器的检测限和样本通量。贵金属加工厂和精炼厂将会体验到高精度仪器的优势。在确定同位素比率方面可以开发新的应用，还可以将精确的同位素比率分析应用到使用同位素稀释法进行元素含量的定量分析中。通过这种方法，地质实验室可以更加准确地表征样本。

　　背景知识：ICP-MS

　　30年来， 电感耦合等离子发射质谱(ICP-MS)已经成为元素分析规定的检测方法：根据不同元素的质量分析元素含量。将液体样本用一个喷雾器喷射到离子化的、1000摄氏度的氩等离子体中。之后离子通过真空接口被转移到离子选择器中，聚成一束并且在质谱中聚焦。质谱根据质荷比将离子束分离。检测器记录离子，实现元素含量分析。独特的离子光学组合、质谱仪和检测器使新型的SPECTRO MS 成为全球首台分离和同步检测全部离子束的ICP-MS。

　　SPECTRO MS Simultaneously Records the Contents of More Than 75 Elements With Approx. 210 Isotopes

A New Era in ICP Mass Spectrometry:
SPECTRO MS Simultaneously Records the Contents of More Than 75 Elements With Approx. 210 Isotopes

New ICP-MS records the elements from lithium to uranium with every analysis
Novel Direct Charge Detector and new ion optic guarantee extraordinary precision and high sample throughput
Records contents of different isotopes opening new application areas
Detailed information about SPECTRO MS available at http://ms.spectro.com

Kleve, March 1, 2010 ?With the SPECTRO MS at Pittcon 2010 (Orlando/Florida, February 28 until March 5, 2010) SPECTRO presents the first fully simultaneous measuring mass spectrometer with inductively coupled plasma (ICP-MS; see “Background?section) in the world. The SPECTRO MS records the entire elemental spectrum between lithium and uranium for every analysis. Users achieve a greatly increased sample throughput rate and much better precision and accuracy compared to using a sequential mass spectrometer.

“The SPECTRO MS will change mass spectrometry forever. The option of being able to measure simultaneously will create a revolution on the market similar to the one created by the optical emission spectrometers several years ago,?reports Manfred Bergsch, SPECTRO抯 Managing Director. “The SPECTRO MS delivers not only much more precise and reproducible results than a conventional mass spectrometer, but also measures a great deal faster; opening new perspectives and applications for laboratories.?

Simultaneous recording of the entire spectrum is enabled by a series of newly designed high-end components:

A novel ion optic that is extremely efficient in transporting ions from the plasma into the mass spectrometer itself ?while reliably removing neutral particles and photons from the beam.
A double focusing sector field mass spectrometer with a Mattauch-Herzog design. An electrostatic analyzer and a permanent magnet are utilized to direct the ions onto a focal plane ?without additional scanning of the ion beam.
An extremely powerful Direct Charge Detector with 4,800 channels is placed in the focal plane of the mass spectrometer recording simultaneously the entire mass spectrum from lithium to uranium with an average of 20 channels per isotope. Each of these channels is additionally divided into two separate detectors with different signal amplification. This enables the SPECTRO MS to achieve a dynamic working range that allows even extreme isotope ratios to be precisely determined.
With the innovative sleep-mode, the robust and user-friendly vacuum system features very low energy consumption.
The housing, software and excitation technology for the SPECTRO MS are closely related to those of the ICP-OES flagship, the SPECTRO ARCOS. A robust, free-running 27.12 MHz generator is used as the plasma generator in the new instrument; guaranteeing extremely stable power coupling in the plasma.

New Standards in the Research Laboratory
The range of applications for the new SPECTRO MS is diverse. Bergsch: “We see many application areas especially for public and commercial research and development laboratories. The number of samples and the requirements for these institutions are extremely high. The SPECTRO MS can truly demonstrate its strengths here ?precision, reproducibility, detection limits, sample throughput. We will quickly establish the SPECTRO MS as the standard system in this area.?

Revealing Isotope Ratios
In addition to research laboratories, simultaneous mass spectrometry is attractive for many branches of industry: Environmental, chemical and pharmaceutical laboratories profit greatly from the instrument抯 detection limits and sample throughput rates. Precious metal processors and refineries will appreciate the high precision of the instrument. New applications can be developed with the option to examine isotope ratios together with the ability to transfer the precision of the isotope ratio analysis to the quantitative determination of element contents using isotope dilution: In this way, geology laboratories can more accurately characterize samples.

Background: ICP-MS
For almost 30 years, mass spectrometry with inductively coupled plasma (ICP-MS) has belonged to the established procedures for elemental analysis: The element contents are analyzed based on the different masses of the elements. The liquid sample is sprayed with a nebulizer into an ionized, 10,000 degree Celsius argon plasma. The plasma ionizes all of the elements contained in the sample. The ions are transferred into the ion optic by a vacuum interface, bundled into a beam and focused into the actual mass spectrometer. The mass spectrometer separates the ion beam according to the mass/charge ratio. The detector records the ions, enabling an analysis of the elemental contents. The unique combination of ion optic, mass spectrometer and detector makes it possible for the new SPECTRO MS ?as the first ICP-MS instrument in the world ?to separate and simultaneously detect the entire ion beam.
