Scanning Electron Microscope (SEM)
Scanning electron microscope is one of the most powerful and commonly used techniques for characterizing the surface morphology of materials. In addition, an SEM coupled with EDS (Energy dispersive Spectrometer) is used to determine the elemental composition of the sample.

High Performance Preparative Liquid Chromatography (Prep-HPLC)
HPLC is an analytical technique widely used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. The individual component of the sample interacts differently with the adsorbent material used in the column, causing a difference in the rate at which they flow out leading to their separation.

|solvent delivery||Parallel- type double plunger system|
|Flow rate||Upto 150 mL/min|
|Detector||SPD M20A Photodiode Array Detector|

HPLC finds widespread application in Quality control, Analysis and R&D labs of the Biochemistry, Biotechnology, Food, pharmaceutical industry and many other industries where there are high benchmarks for precision, sensitivity and reproducibility.
Fourier-transform infrared spectroscopy
Fourier-transform infrared spectroscopy (FTIR) is a method used to obtain absorption or emission spectrum of a solid, liquid or gas after exposing it to the infrared rays. This spectrometer simultaneously collects the spectral data over a wide range of wavelengths. The raw data (inteferogram) obtained is converted to the actual spectrum by using an algorithm called Fourier-transform.
|Wave number range||7800-350cm-1|
FTIR is chiefly used in the identification of the functional groups present in a sample. It is an ideal analytical tool employed in Pharma industries for the formulation and structural elucidation of drugs. This analysis is instrumental in material identification and verification in packaging, food, chemical and other industries.
Powder X ray Diffractometer
X ray diffraction is one of the most sought after characterization techniques, and is the basic necessity of any R&D lab to start with. One of the major reasons being its non-destructive nature for most of the materials, unlike electrons. Basically, X-rays interact with electrons surrounding the atoms of the target material and the reflected signal gives a variety of information about the inner structure of the material. But, later advances by the advent of high brilliance X-ray sources and drastic improvement in detector technology have led to tremendous improvement in the information that can be obtained from new generation x-ray diffractometers.
D8 ADVANCE ECO is one such all-purpose x-ray analyzer, which can be configured for all powder diffraction applications including phase identification, quantitative phase analysis, micro-structure and crystal structure analysis.

CHI 660E electrochemical workstation integrates almost all common electrochemical measuring and testing technique, including potentistatic method, galvanostatic method, potential scan, potential step, current step, pulsing test, square wave test, cyclic voltammetry, coulometry, electrochemical impedance spectroscopy, and so on. The instrument offers a very wide dynamic range of experimental time scales. For instance, the scan rate in cyclic voltammetry can be up to 1000 V/s with a 0.1 mV potential increment or 5000 V/s with a 1 mV potential increment. The potentiostat/galvanostat uses a 4-electrode configuration, allowing it to be used for liquid/liquid interface measurements, and eliminating the effect of the contact resistance of connectors and relays for high current measurements. The data acquisition systems also allow an external input signal (such as spectroscopic) to be recorded simultaneously during an electrochemical measurement.

Thermal analysis is the characterization of a sample of matter based on the properties related to temperature changes. These properties include heat-related phase changes and degradations, crystallizations, heat capacities, heats of reaction, glass transitions, curing rates for adhesives, and weight changes. Even though there are more than a dozen thermal analysis techniques, this program is confined to thermogravimetric analysis and differential thermal analysis, which are the most versatile methods. Thermogravimetric analysis (TGA) is a technique in which the weight of a sample is monitored during the controlled temperature program. Differential thermal analysis (DTA) is a technique in which the temperature difference between the sample tested and a reference material is measured while both are subjected to the controlled temperature program.
Differential scanning calorimetry (DSC) is a technique in which the heat ﬂow difference between the sample and reference material is monitored while both are subjected to the controlled temperature program.
