A spot of crude plant extract was placed on a glass plate coated with C18 silica gel. The chromatogram was developed using an appropriate solvent. The result is shown below. Which of the following spot is the most soluble in water?
True or False: Liquid-solid phase column chromatography is used to separate large up to multigram amounts of mixtures, based on their differences (however small) in polarity.
Researchers used gas chromatography to determine the % v/v methyl salicylate in rubbing alcohol [Van Atta, R. E.; Van Atta, R. L. J. Chem. Educ. 1980, 57, 230-231]. A set of standard additions was prepared by transferring 20.00 mL of rubbing alcohol to separate 25 - mL volumetric flasks and pipeting 0.00 mL, 0.20 mL, and 0.50 mL of methyl salicylate to the flasks. All three flasks were diluted to volume using isopropanol. Analysis of the three samples gave peak heights for methyl salicylate of 57.00 mm, 88.5 mm, and 132.5 mm, respectively. Determine the % v/v methyl salicylate in the rubbing alcohol.

Q. No. 5 Write functions and procedure of analysis of various volatile organic molecules by using Gas chromatography
A method of quantitative determination of the concentration of constituentsof a sample analyzed by gas chromatography is area normalization. Thiscomplete elution of all sample constituents is required. Thearea of each peak is measured and corrected for the detector response to the diffe- renteseluatos. This correction involves dividing the area by an empiricalcorrection factorDetermined. The concen ration of the analyte is found from the ratio between itscorrected and the total corrected area of all peaks. For a chromatogram containing threerelative areas were determined as 16.4; 45,2; and 30.2, in the order ofincreased retention time. Calculate the percentage of each compound if therelative responses from the detector are 0.65, 0.73 and 0.85, respectively.
Is longitudinal diffusion of the solute a more serious problem in gas or in liquid chromatography? gas chromatography O liquid chromatography Why is longitudinal diffusion a more serious problem in this type of chromatography? Gas chromatography is carried out at higher temperatures than liquid chromatography. The solute must be volatile for application of gas chromatography. The linear velocity in gas chromatography is greater than the linaer velocity in liquid chromatography. Diffusion coefficients of gases are much greater than those of liquids.
