General Information |
Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry that uses an Inductively coupled plasma to ionize samples. ICP-MS is an analysis technique that provides fast, cheap and accurate qualitative, quantitative or semi-quantitative measurement of a large number of elements in liquefied samples with high precision in the ppt -% weight measurement range. It atomizes the sample and creates atomic and small polyatomic ions, which are then detected. It is known and used for its ability to detect metals and several non-metals in liquid samples at very low concentrations. It can detect different isotopes of the same element, which makes it a versatile tool in Isotopic labeling. The ICP-MS device provides the argon plasma, which is brought to a temperature above 8.000oC by electromagnetic induction, to break the molecular bonds and ionize the sample at high temperatures. First of all, it should be ensured that the sample to be ionized by spraying it into argon plasma is liquefied in a solution. In general, The samples are made liquid by disintegrating or dissolving in acidic aqueous solutions. The sample in the solution is sprayed to the nebulizer and spray islet via sample introduction part of divice. Then, the samples in the form of small droplets that used to stimulate the relevant elements are combined with argon plasma to be ionized at high temperature. The ions obtained are sent to the Vacuum System, which is a high vacuum environment, through the sampler cone and skimmer cone. The ionized sample is directed to the mass filter by focusing on the Quadropoles via Ion Lenses. These ions are separated according to mass /charge (e/m) ratios in the mass spectrometer and measured by the detector. |
Sample Preparation |
Except for water and its derivatives (waste water, etc.), samples that can be liquefied by microwave combustion can be examined from liquid and solid samples. Water and its derivatives can be examined after filtration or directly on the device depending on the amount of particles in their content. |
Usage Area |
Detection of nearly 50 elements such as Mercury, Arsenic, Lead and Tin can be performed in samples above with ICP-MS. |
