ICP-MS

In times of increased environmental awareness it is important to have an analysis method that can give you detailed information about trace elements in different substances like water, ground, stone and sediments. It is also important in the food, nuclear or medical industry, whereby the ICP-MS (Inductive coupled plasma mass spectrometer) is used to identify trace elements.

Application requirements

  • Different vacuum pressures in different stages
  • High reliability
  • Low power consumption

How does it work?
The ICP-MS is based on the ionization of the material that is to be analyzed with a plasma at about 5,000°-10,000°C. To produce the plasma, a high frequency current is applied to ionized Argon. Out of the plasma, the ions pass through two blinds, which are named sampler and skinner, to the vacuum system of the mass spectrometer. After focusing by the ion lens, the ion beam will separated in the mass filter system.

Because of the different vacuum pressures that are needed in the ICP-MS, the used turbopump is the core of the vacuum system. Therefore Pfeiffer Vacuum is the best contact to create an customized SplitFlow turbopump, to evacuate different vacuum stages with only one pump. To reach this pressure range you also need a backing pump. There are various variants possible such as dry backing pumps like diaphragm pumps or roots pumps but also rotary vane pumps. Because an ICP-MS can be coupled to an gas- or liquid chromatograph, you have different requirements to your backing pump. To have an overview about your working pressure, Pfeiffer Vacuum can offer you a wide product range of different gauges. . With the RS-485 interface, most of the products from Pfeiffer Vacuum can communicate with each other, resulting in one controller for your entire vacuum system.
