INDUCTIVELY COUPLE PLASMA MASS SPECTROMETRY

In the Inductively coupled plasma mass spectrometry (ICP-MS), a large amount of elements of the periodic table can be quantified at trace and ultratrace concentration levels.

The liquid sample is transported through the tubing connections with a peristaltic pump. When the liquid reaches the nebulizer system it becomes an aerosol thanks to the action of gas argon. The aerosol is conducted to ionization zone that consists in a plasma generated when subjecting a flow of gas argon to the action of an oscillating magnetic field induced by a current of high frequency. Inside the plasma temperature reaches to 8000ºK. Inside the plasma, atoms of the sample are excited and ionized.

The ions are transported inside the cuadrupolar analyzer through an increasing vacuum interface. Then ions are separated by its charge/mass ratio. The ions arrive to the detector and the abundance in the sample is evaluated.

Applications

An ICP-MS device can detect and quantify the majority of the elements of the periodic table, being able to analyze a wide range of samples.

Determination of metals and contaminants in soils, pesticides, vegetal matters, foods, etc.

Determination of toxic elements in urine, blood, animal tissue, breast milk.

Analysis of rare earths in sediments and rocks to determine its origin.

Evaluation of the pollution of soils.

Analysis of isotopic alterations of some elements

Determination of metals in continental water, drinking water, waste water and sea water.

It has also the possibility to carry out semiquantitative determinations without the need of any standard. The instrument can make a scanning in all the range of masses providing information about all the elements of the periodic table

 

Equipment

 Accessories and gases

The instrument have an autosampler for the automatic introduction of the samples.

Argon is used as the main gas for all the applications, and oxygen in the case of organic matrixes.

 

ICP-mass

Co-financed by 80% by funds of the P.O. ERDF 2007 / 2013 from Comunitat Valenciana and by 20% by the Generalitat Valenciana
