Scope of ICP-MS applications

Pekin Elmer Nexion ICP- MS Spectrometer

ICP-MS is acclaimed widely as the most sensitive and accurate technique for analysis of traces metals. It has an established application base in studies on pharmaceutical and food products. However, there are some other areas as well where ICP-MS has made inroads and regulatory bodies across the world have specified ICP-MS as the recommended technique for framing the upper limits of toxic elements in both natural resources and commercially manufactured products. Some such application areas are briefly covered in the article.

Manufacture of Semiconductor devices

Semiconductor devices have contributed significantly to the advances in electronics. The behavior of semiconductor devices is influenced to a large extent by contamination due to some elements in ultra-trace levels. Slight variations in their concentrations can result in marked behavior changes of such devices and can lead to even failure under the required operating conditions. Such impurities can get introduced through water, reagents or presence on the surface of wafers. Unwarranted presence of such impurities can result in operational problems of such devices.

ICP-MS affords detection of metallic impurities in sub-ppm to ppb and even ppt or lower levels. However, utmost environmental control of laboratory, use of highest purity reagent grades and above all personal hygiene make the significant contribution to the reliability of results.

Nuclear Energy

Power generation is not limited to thermal and hydroelectric modes. The alternate energy resources exploited are nuclear, solar energy and tidal energy in coastal areas. Nuclear power plants are a viable and safe option provided required safeguards are in place.

Isotopic ratios of different species can be determined as well when HPLC is also added to ICP-MS. This unique feature helps establish the isotopic ratios of radioactive elements such as Uranium, Thorium, Plutonium and other radioactive species that can result from nuclear fission reactions. This makes ICP-MS a valuable tool for exercising control over radioactive by-product waste, radioactive dating, and monitoring of fuel burn up in the reactors.

Forensics and Clinical Toxicology studies

In criminal investigations, it is observed that there is an exchange of microscopic quantities of trace metals between the criminal or the crime weapon and the subject of investigation. Such minute quantities can be easily detected in specimens such as broken glass bits, car paint chips, soil, bones, teeth, hair or pieces of clothing  recovered from the scene of the crime . In cases of suspected poisoning, the examination of viscera for heavy metals such as mercury, cadmium, lead can be detected using the ICP-MS technique. The same techniques can be adapted to study the presence of trace metals in body fluids such as blood, urine, etc in clinical studies.


Laser ablation ICP-MS systems find special mention in Geological studies on specimens such as rocks, soils, minerals, water, ice glaciers, metrological specimens and other extra-terrestrial rocks. Such studies help exploit the potential of reservoirs of natural resources and also their feasibility for consumption and refining. Studies on isotope ratios on isotopes lead to studies on geological and climatic aging.


ICP- MS makes it possible to determine metals as well as most of the non- metals present in environmental samples such as air, water and complex vegetable and animal matrices. In industries, ICP-MS is of immense use in getting valuable information on studies on oil leaks, sludges, industrial discharge and solid wastes.ICP-MS is also a recommended technique for trace metal contamination of water used in manufacturing operations and for human consumption.

It can be concluded that ICP-MS offers a vast scope of applications in diverse areas of human activity because of its high speed of analysis and ultra-trace level detection of both metals and non-metals in diverse sample matrices.

  1. Dear Dr. Deepak Bhanot,

    I would like to GENUINELY appreciate you from the inner part of my heart so much for the free gift of knowledge you have been giving us together with your team concerning the analytical data and appropriate use of analytical equipment as well as maintenance. You are such an incredible person worth of his salt for the earth! I have immensely benefited from your unlimited supplied reservoir of scientific knowledge and I am so grateful to you. Keep up with the good works to change the world with scientific solutions that everyone needs! I wish a lot more of people like you could selflessly be resourceful as you are in their area of specialization for many many years like you have done in the past, this world would have been different scientifically. We desperately need the scientific proofs than those who existed centuries ago. If many of us we were exposed to such advancements from inception, we would not have been what we are today. I am so grateful to you for your constant updates and resilient attitude towards changing a “blank world” somewhere. Please never give up to good for mankind, you deserve to live more than what is estimated for man on this planet because your sacrifice and contribution to look and share detailed information for others out there, is so significant and immerse that we can not afford to archive it in the grave museum so soon before any progressive mind of a scientist comes on board to grasp what is available to change the world for the upcoming generation.

    1. Dear Golden Zyambo,
      Many, Many thanks for your lofty words of appreciation of my efforts and mission.I am no one to judge myself . Opinion of others always counts. Honestly I do not know if I deserve such appreciation.However, there are so many distinguished professors, specialists and learned men around. Analytical science is only one branch in the tree of knowledge. Hope they also make such contributions in their respective fields so that the common layman can get a ray of enlightenment and come to know about the progress made by mankind over the years.
      Once again thanking you for your kind words.
      Best Regards
