LABORATORY :

Nav Bharat Metalic Oxide Industries Pvt. Limited has trained production personnel alongwith a state-of-the-art quality assurance department to ensure the quality norms.


INDICATIVE LIST OF OUR LABORATORY EQUIPMENTS:

INSTRUMENT: ATOMIC ABSORPTION SPECTROPHOTOMETER

MODEL:
AAS-300

MAKE: PERKIN ELMER CORPORATION (Switzerland)

PRINCIPLE: Ground state atoms absorb light energy of a specific wavelength which is a characteristic of the element to be analysed. Amount of energy absorbed gives the quantitative determination of the element of interest.

APPLICATION: Determination of Al, Co, Cu, Fe, Mn, Ni , As, Ca, Cd, Cr, In, Mg, Na, Pb, Sb, Si, Zn, etc. up to ppm level.



INSTRUMENT:
Weighing Balance

MODEL: BP211D

MAKE: SARTORIUS AG(Germany)

RANGE: 0.00001gm to 210gms.
 


 

INSTRUMENT: pH - METER

MODEL: CYBER SCAN 510

MAKE: EUTECH INSTRUMENTS

PRINCIPLE: The principle is based on Poggendorff's compensation method to balance the unknown e.m.f against a known e.m.f, which can be easily varied.

APPLICATION: Determination of pH of aqueous solutions.


 

INSTRUMENT: SURFACE AREA ANALYSER

MODEL: SMARTSORB-90

MAKE: SMART INSTRUMENTS Co.

PRINCIPLE: According to Brunaer, Emmet, Teller theory, at a known partial pressure, Amount of N2 absorbed by sample (Ncs) at Liq. Nitrogen temperature can be expressed in the form of mathematical expression, involving physical terms such as partial pressure of the gas (p), volume for monolayer absorption (Vn), volume absorbed at equilibrium pressure (Ncn), Sample weight (Ws), etc.

SURFACE AREA: 4.38 x (Ncs x Vn)/(Ncn x Ws) x 273/(273+T) x (1-p/p0)

UNIT: (m2 / gm.)

APPLICATION: Determination of surface area from 0.2 to 1000 m2/gm.  


INSTRUMENT: U.V. SPECTROPHOTOMETER

MODEL: SL-171

MAKE : ELICO LTD.

PRINCIPLE: According to Beer - Lambert's Law, when a beam of a monochromatic light passes through transparent medium, intensity of the emitted light decreases exponentially as the concentration of absorbing substance increases arithmetically.

APPLICATION: Determination of Al, Co, Cu, Fe, Mn, Ni etc.


INSTRUMENT: D.C.Polarograph

MODEL: CL-357 & CL-25D

MAKE: ELICO LTD.

PRINCIPLE: Polarography is an electrochemical method of analysis for both detection & determination of element in solution. It defines the current voltage relationship (polarograms) on electrolyzing an electro- oxidisable or electro-reducible solution in a polarographic cell.

APPLICATION: Determination of Pb, Cd, Sn, etc.
