Click to ViewThe ICP-MS is used for analysis of the elements at trace levels. It combines a high-temperature Plasma system with a quadruple mass analyzer. The elements in the sample are converted into ions, they are then brought into the mass spectrometer via the interface cones. Once the ions enter the mass spectrometer, they are separated by their mass-to-charge ratio and then quantified using detector.

  Working Principles
Click to ViewInductively Coupled Plasma Mass Spectrometer (ICP-MS) couples use of an ICP with MS for elemental analysis by generation of ions. The ICP is involved in generation of a high temperature plasma source at 10,000 degree Celsius, through which the pre-treated sample is passed. Plasma is a stream of highly ionized gas containing an equal number of electrons and positive ions. It is electrically conductive and is affected by magnetic field. The high temperature attained by this plasma inside the system helps in ionization of elements and thereby in detecting them. Mass spectrometer is used as detector.

  Applications
  User Instructions
It is used mainly for quantitative analysis of elements at trace level.Following elements can be analyzed: Multi-elements: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, In, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, TI, V, U, Zn, B, Ge, Mo, Nb, P, Re, S, Si, Ta, Ti, W, Zr Rare earth element: Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu 1. Element will be only analyzed from soil, water and plant samples. 2. Micro wave digested sample should be submitted in solution form specifying the elements to be estimated and their approximate concentrations expected, but the Total dissolved Solid in the solution should not exceed preferably 500 ppm. 3. In case Microwave digestion has to be done, the same may be communicated to the Incharge. 4. Generally 10 ml of solution is sufficient for estimation of about 10 to 15 elements. 5. Explosive, poisonous samples and samples giving rise to toxic gases/fumes cannot be undertaken for ICP-MS analysis. 6. A minimum of 20 samples should be submitted for analysis. 7. The user should specify if their samples have HF content as glass is part of the spray chamber. 8. The concentration of analyte in samples should be less than 100 ppb for ICP-MS.
