Unformatted text preview: accelerate the separation and identification of the sample components. It produces nicely shaped peaks and a total analysis time shorter than the isothermal operation. Very interesting method, and with the improvement of technology in the device used in this experiment, a printout including: retention time, area and % area under peak, height and even the ( 29 ppm 12446 13206 12862 12122 standard of Area unknown of Area C6 ppm 3206 1 1 1000 1000 10 6603 . 100 2 C6 412 . 3 Unknown the of Time Re 12122 C Unknown the of Peak 181 . 3 Standard the of Time Re 12862 C Standard the of Peak tan unknown 3 6 3 standard 6 6 = × = = = = = = = = dard s C Peak Peak g mg L cm cm g tention Area tention Area concentration was displayed for all components present in sample....
