  Working Principles
Click to ViewInductively Coupled Plasma – Atomic Emission Spectrometry (ICP- AES) is an emission spectrophotometric technique, exploiting the fact that excited electrons emit energy at a given wavelength as they return to ground state after excitation by high temperature Argon Plasma. The fundamental characteristic of this process is that each element emits energy at specific wavelengths peculiar to its atomic character. The energy transfer for electrons when they fall back to ground state is unique to each element as it depends upon the electronic configuration of the orbital. The energy transfer is inversely proportional to the wavelength of electromagnetic radiation, E = hc/ λ … (where h is Planck’s constant, c the velocity of light and λ is wavelength), and hence the wavelength of light emitted is also unique. Although each element emits energy at multiple wavelengths, in the ICP-AES technique it is most common to select a single wavelength (or a very few) for a given element. The intensity of the energy emitted at the chosen wavelength is proportional to the amount (concentration) of that element in the sample being analyzed. Thus, by determining which wavelengths are emitted by a sample and by determining their intensities, the analyst can qualitatively and quantitatively find the elements from the given sample relative to a reference standard. The wavelengths used in AES ranges from the upper part of the vacuum ultraviolet (160 nm) to the limit of visible light (800 nm). As borosilicate glass absorbs light below 310 nm and oxygen in air absorbs light below 200 nm, optical lenses and prisms are generally fabricated from quartz glass and optical paths are evacuated or filled by a non absorbing gas such as Argon.

  User Instructions
ICP-OES is used for a wide range of applications in the following industries: • Environmental • Oil Analysis • Pharmaceutical • Food • Petrochemical • Mining • BioFuels • Soil samples • Plant tissue samples Sample should be submitted in solution form specifying the elements to be estimated and their approximate concentrations expected, sample preparation technique (use of acids/solvents) should also be provided. Organic solvents cannot be accepted. The organic solvent has to be either volatilised or destroyed. Registration should be done for analysis 45 days in order to enable us for procurement of chemicals etc. as per your need. Explosive, poisonous samples and samples giving rise to toxic gases/fumes cannot be undertaken for analysis. It is advisable to send about 25 ml of solution. Generally 25 ml of solution is sufficient for estimation of about 10-15 elements depending up on their concentration. For special samples like rocks / ore samples, appropriate standards along with the samples should be submitted by user. Explosive, poisonous samples and samples giving rise to toxic gases/fumes cannot be undertaken for ICP-AES analysis. Upper limit for the number of samples acceptable for ICP-AES laboratory is 200 per week. Samples should not have HF in the solution. Excess HF should be evaporated completely or may be neutralised using Boric Acid.
