GC-MS is a powerful analytical technique for separation, identification and quantification of volatile organic and inorganic compounds in a solvent mixture. It is an elegant interfaced instrument, in which the Gas chromatography (GC) first separates the components of a mixture and then the coupled Mass spectrometer (MS) characterizes each of the separated components individually. The components are separated based on their relative affinity or retention time of the individual compounds. read more »
Identification
Abhijit ChatterjeeInverted Microscope, Nikon Eclipse TE-2000U
This microscope has its light source and condenser on the top, above the stage pointing down, while the objectives and turret are below the stage pointing up. The stage on an inverted microscope is usually fixed, and focus is adjusted by moving the objective lens along a vertical axis to bring it closer to or further from the specimen. The focus mechanism typically has a dual concentric knob for coarse and fine adjustment. read more »
