[pic] Liquid chromatography labs are composed of six main parts: a. A separation column filled with a fine-grain solid. b. A solvent (mobile phase) that moves through the separation column. c.An injection system to transport the solvent to the separation column. d. A pump to force the solvent through the separation column. e. A detector to determine when the components exit the separation column. f. A recorder [pic] Although in most chromatography labs the solid phase is polar and

an eco-column lab is to show the similarities between that and a real world. It is a useful tool for learning because you get to create and see your own little world. It is very much like the real world because of the communities of organisms that it consists of‚ along with their physical environment. An eco-column is a closed system. In a closed ecological system‚ any waste products produced by one species must be used by at least one other species. All materials used in the eco column have abiotic

A good example of a Greek temple‚ is the Temple of Hera which‚ uses Doric order. This temple has columns that are four times as high as they are wide‚ making them very robust. The Temple of Hera has a total of nine columns and the entrance contains three of them. This causes the entrance to have

Beam Chopping corrects for flame emission but not for scattering. Can distinguish the signal of the flame from the atomic line at the same wavelength. The higher the absorbance the higher the transmittance. Intro to IR Near IR- (0.78 to 2.8 micrometers) Mid IR- (2.5- 50 micrometers) Far IR- (50-1000 micrometers) Most common region used is Mid IR btwn 2.5- 15 micrometers Mid IR: based on diffracting gratings but now current instrumentation are of Fourier transform type Far-IR: useful
