At present working as Laboratory Executive in application &
Wet laboratory, working on AAS, GC, HPLC,
Spectrophotometer for the analysis of Soil, Air, water
(Ground, Surface, Sewage, Industrial effluents) as well as
pharmaceutical product. And report submission of samples.


• Work on multitudes of aspects in the lab apart from
analysis.

• Analysis of Volatile Organic Carbons, PCB’s, PAH,
Phenols, CO, CO2 using methanizer,
FAME analysis .
• Developed a perfect hand in utilization, handling
and maintenance of GC (All netel
manufacturing ), HPLC (Water TM 486),AAS
(PerkinElmer),UV-VIS
Spectrophotometer.(Thermo-Orion)
• Having a Knowledge of making S.S. Columns and
method development.

1.Analysis of Different Types of Raw Material, Tablets,
Syrup, Perfume, Injections, Oils etc.

Worked On :
 Gas Chromatography (MACRO 9100, Ultima-2100,
Analyte-2700, Platina, (All Netal GC)
 HPLC - Saif Water HPLC (Double Piston Pump)
 Water TM 486 Tunable absorbance Detector (Single
Piston Pump)
 IR: FTIR -410 Jasco

2.Gas Chromatography:
 Separation Of components from mixture using CHEMITO
8310 Gas Chromatograph
3.Spectrophotometer Mtd. Of s analysis:
 U.V. Visible Spectrophotometer (ELICO INDIA SL-
159), Visible Spectrophotometer (ELICO INDIA SL-171,
Colorimeter (ELICO INDIA), Polarometer, Nephelometer,
Florometer, Flame Photometer etc.
4.Industrial Chemical Analysis:
