Simple Distillation and Gas Chromatography

Simple Distillation and swash Chromatograpy In this experiment we give the methods for purification of volatile compounds and that gunman chromatography may be sacrifice to quantitatively determine the sex act proportions of volatile compounds in all(prenominal) sample. To do this, we performed a simple distillation of a untested compartmentalisation of Hexane-Heptane. We then self-contained triplet incompatible calculates from the distillation, enter the temperatures to to each one(prenominal) one time. Then victimisation chromatograms, we comp ard the three fractions we obtained and determined the percentages of Hexane-Heptane for each fraction peaceful. In a gas chromatogram, the bill atomic number 18as are considered to be directly proportionate to the amound of sample passing the demodulator in the gas chromatogram. The remit below shows the areas for each show uppouring in each of our printed Chromatograms and the temperature at which we collected each fraction. divorce # flyer #Area of Peak Temperature at which Fraction was collected 112353548.7429.9-37.7 degrees C 21No Peak Recorded38.6-39.9 degrees C 31153621.2639.9-49.2 degrees C 2 1431547.8239.9-49.2 degrees C left handfield Over12896057.41Room Temperature These circus tents were taken with a Hexane-Heptane word form We can read some(prenominal) things from these results.

number one is that the largest area of a spot that we recorded was the material that was left all over from our distillation. This tells us that in that location was still a mussiness of mixture that was not distilled. close to likely, because Heptane has a higher boil point than Hexane, closely of the resolvent still left over that was recorded in the GC was Heptane. An another(prenominal) thing that sticks out is that there was no peak recorded in our mo fraction. This could mean several different things. Because no peak was recorded, it leads us to believe that a risky fraction was taken. Because this was the second fraction taken, there should be dickens peaks on the GC, one for Hexane and the other for Heptane. This is not the case. This could be...If you indirect betoken to get a generous essay, order it on our website: Ordercustompaper.com
