We offer consultancy services in the following areas

Analysis of powder materials using X-Ray Powder Diffraction is one of the most powerful and well established techniques for material characterization. This technique is capable of providing information about the structure of a material at the atomic level. We offer consultancy in the following levels, Powder X-ray measurement, Pattern indexing, Reitveld refinement, Structural determination.

FT-IR Spectroscopy, The infrared spectrum originates from the vibrational motion of the molecule. The vibrational frequencies are a kind of fingerprint technique for the compounds. The band intensities are proportional to the concentration of the compound and hence qualitative estimations are possible with this measurement. IR absorption has numerous applications in qualitative and quantitative analysis. We offer consultancy in the following level, FT-IR spectrum of samples, Structural analysis of bands and Functional group analysis.

UV-Vis Spectroscopy, The optical absorption by samples in the ultraviolet and visible regions is measured with this instrument. Absorption measurements in the UV and visible regions provide information about electronic transitions in a sample. We offer consultancy in the following level, UV-Vis spectrum of liquid sample, Structural analysis of electronic bands.

Thermal Analysis: Thermal analysis is a group of techniques in which the physical property of a substance is measured as a function of temperature, while the substance is heated through a controlled temperature program. The properties include change in weight [(Thermogravimetry (TG)], temperature difference [(Differential Thermal Analysis (DTA)] and heat flux difference [(Differential Scanning Calorimetry)] TG-DTA/DSC. DSC method can be used for the analysis of following phenomena, Melting/crystallization behavior, Solid-solid transitions, Polymorphism, Degree of crystallinity, Glass transitions etc. We offer consultancy in the following level, TG-DSC and TG-DTA pattern of samples, Analysis of weight loss, Melting/crystallization, Polymorphism and Degree of crystallinity, Thermal stability of the solid state materials.

Fluoroscence Spectrometer: It is a powerful technique that is used for a variety of environmental, industrial, medical diagnostics, DNA sequencing, forensics, genetic analysis, and biotechnology applications. Fluorescence is the molecular absorption of light energy at one wavelength and its nearly instantaneous reemission at another wavelength, usually longer, wavelength. Fluorescent compounds have two characteristic spectra which are 1) an excitation spectrum (the wavelength and amount of light absorbed) 2) an emission spectrum (the wavelength and amount of light emitted). These spectra are often referred to as a compound's fluorescence signature or fingerprint. We offer consultancy in the following level, excitation or emission spectra of liquids and solid samples, Analysis of the spectra.

Magnetic measurements

The magnetic moment measurements of compounds are made Vibrating Sample Magnetometer (VSM) machine. This is a nondestructive technique. The magnetic susceptibility value is helpful in the determination of the oxidation state of paramagnetic ions. We offer consultancy in the following level, Analysis and interpretation of hysteries, saturation magnetization, calculation involving magnetic measurement and analysis of the spectra.

We also offer consultancy services in the field of Mossbauer Spectroscopy.
