High Performance Liquid Chromatography (HPLC)
High performance liquid chromatography (HPLC) is one mode of chromatography, the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases.
(e.g. It is used to quantify the amount of organic pollutants in waste water) |

Fourier Transform Infrared (FT-IR) Spectrometer
| Infrared spectrometer can be used to identify materials, determine the composition of mixtures, monitor the course and extent of reactions, and provide information helpful in deducing molecular structure. Analysis is based on the fact that molecules have specific frequencies associated with internal vibrations of groups of atoms. FT-IR spectrometer employs an interferometer in place of a monochromator mostly used in dispersive infrared spectrometer.(e.g. It can be used to analyse the concentration of SO2 in air) |

Atomic Absorption Spectroscopy (AAS)
Atomic absorption spectroscopy (AAS) is a technique for determining the concentration of elements in solution. AAS is specific and characteristic for each element.
(e.g. It can be used to determine the amount of heavy metal in industrial sewage up to ppm level) |

Gas Chromatography-Mass Spectrometry (GC-MS)
Complex volatile mixtures can be separated by gas chromatography (GC) and analyzed by Mass Spectrometry (MS). It is usually the first analytical choice of quantitation of mixtures of the more volatile organic compounds.
(e.g. It can be used to quantify and identify organic compounds such as pesticides in wastewater) |

UV-Visible Spectrometer
The broad region of the electromagnetic spectrum finds its principal application in quantitative analysis of materials as neat liquids, dilute solutions, films and powders. The ultraviolet and visible regions of the spectrum provide information about the electronic structure, especially for aromatic and transition metal compounds (e.g. It can be used to measure the decolourization of dyes)
X-ray Fluorescence Spectrometer (XRF)
X-ray fluorescence (XRF) spectrometry is simple and nondestructive method for qualitative and quantitative analysis of elemental composition on a wide range of materials. The method is extremely useful because of the ease of sample preparation and because of its ability to detect and analyze elements down to aluminum and, under certain circumstances, to boron.
