Having more than 25 years of experience to lead the chemical industry, we apply our total quality assurance expertise to provides SEM testing, XRD testing, XRF testing, Particle size Analysis testing & Surface Area testing, Bulk & True density testing facility in India.
Using these modern testing facilities we utilize a combination of techniques that determine identity, composition, impurities and chemical quality with molecular and chemical structure confirmation to meet the highest Quality Standards for our clients.


XRF is a technique that determines the elemental composition of materials. It determines the chemistry of a sample by measuring the fluorescent or secondary X-ray emitted from a sample when it is electrified by a primary X-ray source. XRFtesting facility is a non-destructive analytical technique.


The XRD is used to identify single crystals, and to reveal the structure of single crystals. It can also be used to identify crystals which are present in a mixture as minerals in a rock. XRD testing facility is the best method for identifying minerals with variable formulas and structures, such as clays and determining their proportion within a sample.


SEM is a powerful investigative tool that uses a focused beam of electrons to generate complex and high magnification images of a sample’s surface topography. Using the SEM testing facility, a deeper detail of material is analyzed with energy-dispersive x-ray spectroscopy.


Particle size analyzer characterizes the size distribution of particles in a given sample. It can be applied to solid materials, emulsions, suspensions, and even aerosols. Many different methods are employed to measure particle size. Selecting the most suitable method is quite important for different samples as different methods produce quite different results for the same material.


Bulk density is a property of granules, powders, and alternative solids, particularly utilized in respect to mineral elements, chemical substances, ingredients, foodstuff, or the other lots of vegetative cells or material. Bulk density isn’t a natural property of a material; it changes depending on how the material is picked up.


Helium Gas is used while measuring true density since it’ll penetrate each surface flaw down to about one angstrom, thereby allowing the measurement of powder volumes with noble accuracy. The calculation of density by helium displacement usually reveals the presence of impurities and occluded pores which can’t be decided by the other methodology. This method is known as True Density Testing.


Brunauer Emmett Teller (BET) theory is a very important analysis technique for measuring the specific surface area of materials. It describes the physical adsorption of gas molecules on a solid surface and works as the basis for the measurement of the specific surface area. The BET theory applies to multilayer adsorption systems and typically utilizes probing gases that don’t chemically react with surfaces of various materials as adsorbates to quantify specific surface area. Nitrogen is the most commonly used gaseous adsorbate for surface probing and conducted at the boiling temperature of N2 (77 K). BET theory is also applied as a Surface Area Testing/Analyzer technique to determine the specific surface area of activated carbon from experimental data, demonstrating a large specific surface area, even around 3000 m2/g.


The quantity of heat generated by the combustion of fuel at constant pressure and under standard conditions (0 degree C and under a pressure of 1,013 mbar) is known as the calorific value of a fuel. In the combustion process, water vapors are generated and some certain techniques are used to recover the quantity of heat contained in water vapors by condensing it.

Calorific value analyzer is a high-speed process gas analyzer for observance and control of calorific value, Wobbe Index and specific gravity and as a choice, the Air/Fuel ratio of process gas.

When the water of combustion is fully condensed and the heat contained in the water vapors is recovered, It is considered as Higher Calorific Value or Gross Calorific Value (GCV) or Higher Heating Value (HHV) and when the heat in the water vapor is not recovered, we get Lower Calorific Value or Net Calorific Value (NCV) or Lower Heating Value (LHV).


A viscometer is an instrument used to calculate the viscosity of a fluid.

Viscometers use the principle of ‘rotational viscometry’, i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample. As the torque required will be proportional to the quantity of viscous drag upon the spindle, this, therefore, provides an assessment of the product viscosity, reported in centipoise units (cP).
