Meenakshisundaram,

    One of the things you want to consider when buying an inductively
    coupled plasma - optical emission spectroscope (ICP-OES) is the
    sample preparation you will have to do and the type of information
    you want. If you will be analyzing metals, then to use an ICP-OES
    you will need to digest the samples in acid. This involves heating
    the acid either with a hot plate or a special microwave oven. Also,
    you may have to use hydrofluoric acid for the digestion which
    requires special component for the ICP-OES. Not to mention all of the
    hazards associated with the acid. You might consider whether a laser
    induced breakdown spectroscopy (LIBS) system would provide the
    information you need. This will help avoid the whole acid issue
    because you can test a solid metal sample. 

Scott
