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.

2. Inductively Coupled Plasma - Optical Emission (ICP- OES)
   ICP-OES PerkinElmer Optima 7300 DV

   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
   - Forensics analysis
   - Environmental sciences measurements - Food industry

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.

Scanning Electron Microscopy coupled with Energy Dispersive X-ray (SEM/EDX) Spectroscopy:
Nova Nano SEM 450 and Quanta 200 SEM

In scanning electron microscopy (SEM), a highly energetic and focused electron beam scans the sample and normally provides an extremely enlarged image of the morphology of the sample, as well as information on its chemical composition using an energy dispersive spectrometer (EDS) detector. SEM-EDS is mainly used for the characterization of materials, but lately, its application has been extended to study organic-based specimens.

Applications:

• Detection and analysis of surface fractures.
• Examination of surface contaminations.
• Providing information in the microstructure.
• Revelations of spatial variations in chemical compositions.
• Wide applications in life science, biology, geology, medical, forensic science, and metallurgy.

 

 

 

Transmission Electron Microscopy (TEM) FEI TECNAI G2 TEM, TF20

TEM Microscopy technique whereby a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen of the electrons transmitted through the specimen; the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as s CCD camera.

Applications:

Different fields such as life sciences, nanotechnology, medical, biological, and material research, forensic analysis, gemology, and metallurgy as well as industry and education. TEM provides topographical, morphological, compositional, and crystalline information.
