Alfa Chemistry' plasma chemistry laboratories are equipped with state-of-the-art equipment and experienced technicians. We typically use ICP mass spectrometry (ICP-MS) and optical emission spectrometry (ICP-OES) for quantitative and qualitative analysis of elements. Here you can get a plasma elemental analysis service based on Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES).
Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES)
Current instrumentation
The current ICP-AES is a Varian Liberty Series II, which is a sequential instrument.
ICP-AES is best suited for elements in the low weight percent to parts per million-concentration range and has particular advantages over ICP-MS for some elements such as sodium, potassium, calcium, phosphorous and sulphur. The technique can be applied to the determination of elemental composition of a wide variety of material types including geological, environmental, biological.
Sample requirements
Samples for ICP-AES need be introduced as a solution (a liquid phase). Solid samples need be crushed and dried and a suitable method used to dissolve the material (normally accomplished by open vessel or microwave-assisted digestion in acids or, where necessary by fusion techniques). In most instances the AAC will perform sample digestion.
ICP-AES is a well-established and cost effective technique for multi-element analysis. Samples (in solution) are introduced, as an aerosol, into a plasma (at temperatures in the order of 6000-10,000K). This process effectively coverts the elements present to gaseous atoms (then ions), which are elevated to excited states. As the atoms "relax" to a lower excited or 'ground' state they emit light radiation at characteristic wavelengths. A spectrometer is used to separate the light emitted and is detected using a photo multiplier tube (PMT).
