Scientific Instrument Centre

The objective of the scientific Instrument center is to provide support to research, education by access to characterization and process instrumentation in the faculty of science and others in KMITL, and also the public service as well.

Analytical Instruments

  • Differential Scanning Calorimeter (DSC)

    Differential scanning calorimetry is a technique that use to study what happens to a sample when they're heated. We use it to study what we call the thermal transitions of a sample.

  • Fourier Transform Infrared Spectrometer(FTIR)

    Offers quantitative and qualitative analysis for organic and inorganic samples. It identifies chemical bonds in a molecule by producing an infrared absorption spectrum. The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to screen and scan samples for many different components. FTIR is an effective analytical instrument for detecting functional groups and characterizing covalent bonding information.

  • Atomic Absorption Spectrophotometer (AAS)

    An analytical technique that measures the concentrations of elements. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (µg dm–3) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element. They correspond to the energies needed to promote electrons from one energy level to another, higher, energy level.

  • Gas Chromatograph-Mass Spectrometer (GC-MS)

    an instrumental technique, comprising a gas chromatograph (GC) coupled to a mass spectrometer (MS), by which complex mixtures of chemicals may be separated, identified and quantified. This makes it ideal for the analysis of the hundreds of relatively low molecular weight compounds found in environmental materials.

  • X-Ray Fluorescence Spectrometer (XRF)

    an elemental analysis technique with broad application in science (first 11 elements). XRF is based on the principle that individual atoms, when excited by an external energy source, emit X-ray photons of a characteristic energy or wavelength. By counting the number of photons of each energy emitted from a sample, the elements present may be identified and quantitated.

  • X-Ray Diffractometer (XRD)

    A high-tech, non-destructive technique for qualitative and quantitative analysis of crystalline compounds.

  • High Performance Liquid Chromatograph(HPLC)

    A technique in analytic chemistry used to separate the components in a mixture, to identify each component, and to quantify each component. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out the column.

  • Thermogravimetric Analyzer (TGA)

    measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition.

  • UV-Vis Spectrophotometer

    is routinely used in analytical chemistry for the quantitative  determination of different analytes, such as transition metal ions, highly  conjugated organic compounds, and biological macromolecules. In solid state physics, the band gap can be calculated via UV-Vis spectroscopy of a thin film material.

  • Scanning Electron Microscope (SEM)

    A type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that can be detected and that contain information about the sample's surface topography and composition.

  • Contact Angle Analyzer

    A tool to study the wetting behavior of a liquid on solid. Phenomenon like spreadability, absorption, adsorption, dissolution can be studied by contact angle measurement devices.
