INDUCTIVELY COUPLE PLASMA MASS SPECTROMETRY

Inductively coupled plasma mass spectrometry (ICP-MS) is a technic used to determine most of the elements of the periodic table at trace and ultra-trace levels. The liquid sample is transported by a peristaltic pump to the nebulizer system where it is transformed into an aerosol thanks to the action of argon gas. The aerosol is led to the torch, where the plasma is generated. Temperatures of 8000 K can be reached inside the plasma. Under these conditions, atoms present in the sample are ionized / excited. Positive ions are transported inside the cuadrupolar analyser through an increasing vacuum interface where they are separated by its charge/mass ratio. Ions arrive to the detector and the abundance in the sample is evaluated.

 

Applications

Detection and quantification of most of the elements of the periodic table in a wide range of samples.

Determination of metals and contaminants in soils, pesticides, vegetables and foods in general.

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

The ICP-MS 8900 extends the working range with respect to the 7700x model in the following aspects: 

 

 O2 mode mass-shift method for measuring 75As. First cuadrupole (Q1) allows species with mass 75 to enter the cell where As reacts with oxygen to form 75As16O+. Possible interferences in mass 91 were eliminated in Q1.
