ROLL NO:-20081020 PGP-08‚ IPMG OVERVIEW OF THE INDUSTRIAL TRIP An overview of the Oil and Gas sector was developed as we visited the 4 organizations‚ namely GSEG‚ GSPL & GSPC Gas station‚ GSPC-NIKO Resources Limited and SHELL in Hazira. Amongst the companies visited‚ there were both upstream and downstream ones and their effects in the value chain were duly realized. One striking feature

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

Mario Renteria Mrs. Weathers Chem 04a 27 Jan‚ 2012 Lab Report Introduction: A popular technique in separating components of a mixture is paper chromatography. We use paper chromatography to separate mixtures and isolate there components to collect them individually. In this experiment‚ we will use acid- base indicators to help determine the unknown mixture. Acid- base indicators will change in color when the presence of pHs rise and fall when acids or bases are added to a solution. After setting

The Chromatography of Food Dyes and determination Of the Dyes Present in M&M Candies Procedure To complete this lab‚ I first mixed the solvent solution consisting of the proper ratio of water‚ salt‚ and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing‚ with a pencil‚ the appropriate lines and labels. Using a toothpick‚ I added the color to the paper‚ and then repeated until the color was strong. I repeated this step several more

experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the data was graphed it clearly showed the higher rate of red light absorption over green light. These results along with previous research

separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at different rates. Hypothesis: If chlorophyll is removed from the plant‚ then the different pigments in the plant can be visible. Materials: -Spinach -Coin -Chromatography paper -Ruler

experiment was for each student to use column chromatography to separate plant pigments from spinach leaves. Some goals and objectives were to observe the effect of the increasing polar eluent fractions‚ to analyze the different fractions collected‚ and to correlate the structure of the components with polarity and behavior on a chromatographic column. Background The best method for separating mixtures in organic chemistry is chromatography. Chromatography is the separated of a mixture of two or more

Candy Chromatography Background info: Paper chromatography is a logical technique used to separate works of a solution. Three examples of how we apply this technique to real-life would be: contaneminants in water‚ separation of plant pigmentation‚ and analysis of narcotics.

To purify the protein in the cell lysate from lab 1 through nickel affinity chromatography. Protein purification should result in only one type of protein ideally‚ which is the protein of interest‚ wt-DHFR and mut-DHFR in this case. A pure protein allows for further analysis on the protein to be conducted‚ such as its concentration (Bradford assay)‚ its molecular weight‚ and its biological activity. 2.

Ferrocene and Acetylferrocene will be separated using column chromatography. Column chromatography is a separation technique that is used among many disciplines including biology‚ biochemistry‚ microbiology and medicine. Many common antibiotics are purified by column chromatography.1 Column chromatography allows us to separate and collect individual compounds. In this experiment‚ lumen will be the stationary phase‚ and the more polar substance will be retained on the stationary phase longer
