Is there any difference between ICP-AES and ICP-OES ? Can anyone tell me what the most suitable for plant and soil analysis ?
DEAR ILYAAS, There are no differences esp if you want to go for trace elements.
To estimate the micronutrients , it is important to determine their mineral content as well as that of the soil where plants are grown. Since the number of elements to detect is relatively small (generally
ICP OES and ICP AES both are same with their principles. You can use ICP MS also for the determination of soil and plant samples especially micro and trace elements.
I have used ICP/MS and OES for plant analysis. MS method development was easier and results are quicker.
ICP-MS/AES are the same technique, MS/AES are just a modern of Indule Couple Plasma.
Gas Chromatography are the best analytical technique for plant analysis
ICP-OES and ICP-MS can measure multiple elements in a single analytical run. Much lower concentrations of elements present can be measured by ICP-MS.
ICP/MS and OES are the same technique with two different methods of detection, Respectively, based on the optical spectrum and ionic mass
The basis of ICP/ OES method is the excitation of electrons of various elements in an environment called plasma and the diffusion of light after electron comfort.
The ICP/MS source converts elemental atoms into ions into a sample. These ions are then isolated and detected a by a mass spectrometer. The ICP-MS device measures the mass of elemental ions produced by high temperature argon plasma. The ions produced in the plasma are separated from the mass to the load, making it possible to detect and quantify unknown materials.
Atomic emission spectroscopy (AES) is often denoted Optical emission spectroscopy (OES), in particular because acronym (AES) also refer to to Auger electron spectroscopy (AES). ICP OES or ICP- AES is instrumental technique, which is appropriate for determination trace elements in soil and plant samples.
