INDICATIVE LIST OF OUR LABORATORY EQUIPMENTS:
INSTRUMENT:
ATOMIC ABSORPTION SPECTROPHOTOMETER |
MODEL: AAS-300MAKE: 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 BalanceMODEL: 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. |
