1. Inductively Coupled Plasma/ Mass Spectrometer (ICP/MS):
   ICP – MS PerkinElmer- NexIon 300 D

   Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry that uses inductively coupled plasma to ionize the sample. It atomizes the sample and creates atomic and small polyatomic ions, which are then detected. It is known and used for its ability to detect metals and several non-metals in liquid samples at very low concentrations. It can detect different isotopes of the same element, which makes it a versatile tool in isotopic labelling.

   Applications:

   - Water and wastewater treatment measurements.
   - Medical and forensic field, specifically, toxicology.
   - Geochemistry field for radiometric dating, in which for analyse the relative abundance of different isotopes.
   - Detecting inorganic impurities in pharmaceuticals.
   - Metal and semi-metal analysis in deionized water, chemicals, and on the wafer surface.
   - The applications include Environmental, Foods, Semiconductor, Clinical, Chemical/Petrochemical, Pharmaceutical, Consumer Goods, Forensic, Geological, Nuclear, Academic/Research.

   Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is an analytical technique used to determine how much certain elements are in a sample. The ICP-OES principle uses the fact that atoms and ions can absorb energy to move electrons from the ground state to an excited state.

   Applications:

   - Soil, sediment, rocks, minerals, air analysis
   - Geochemistry research
   - Mineralogical analysis
   - Agricultural analysis
   - Forestry analysis

3. Microwave Digestion System
   MARS 6 - Microwave Digestion System

   Microwave digestion is an established technique that has been used for many years. Sample digestions are used to suspend samples in the liquid phase, as this facilitates trace metal analysis. Using a microwave digestion method provides two main benefits: Firstly, using microwave energy in a sealed vessel significantly increases the boiling point of an acid. This extra temperature means samples can be digested faster and more effectively. The other advantage is that it is impossible to completely digest some types of materials using just acids at atmospheric boiling points. In order to digest these types of materials, a higher temperature is necessary. Using the sealed container, as in microwave digestions, this is possible.

   Applications:

   • Sample preparation technique for metals, trace metals, and isotopic analysis in a different matrix.
   • Applied to a broad range of samples including soils, plastics, oils, pharmaceuticals, metals mining, wastewater, consumer products, foods & feed, environmental samples, Petro & energy industry, and many more.
