INDUCTIVELY COUPLED PLASMA TECHNIQUE FOR DETECTION OF METALS Inductively coupled plasma (ICP) is an analytical technique capable of detecting metals at concentrations as low as parts per trillion. It has become a favorite choice for many analytical laboratories to detect trace metals providing accurate and precise measurements required for lower limits of detection. The basic principle involves the emission of light of a characteristic wavelength by the elements to be detected that is further measured. Emission spectroscopy coupled with inductively coupled plasma is a rapid and sensitive method to estimate metals in environmental samples. The metals need to be digested appropriately before determination. Principle: This method is an amalgamation of the ionization efficiency of argon plasma and separation due to mass spectrometry. The energy generated of a radio frequency generator is channelized to argon/helium/nitrogen to produce the inductively coupled plasma. The sample is nebulized at the beginning and further entrained in the argon flow that is the plasma support gas. The torch consists of inner and outer quartz tubes. The inner tube contains the sample aerosol and argon and the outer one contains the argon gas flow to cool the tubes. The high power radio frequency producing generator produces a current in the …show more content…
