In order to obtain data on the molecular weight distribution of coal tar and pyridine extract of char, Gel Permeation Chromatography has been employed to separate the coal tar according to molecular size. The chromatographic system used was a Waters Associates ALC/GPC 201 Gel Permeation Chromatography system with 500 A and 100 A ..mu..-styragel columns. Although the approximate molecular weight range for the columns has been determined by the manufacturer and there are standards of known molecular weight available, it is still necessary to calibrate the columns with coal tars since the calibration curve will be unique for the particular tars that are to be studied. The peak position method and the linear calibration method are both described and the results are compared. 1 reference, 3 tables, 3 figures.
