Step by step
Solved in 2 steps with 1 images
- A GC-MS was used to analyze an unknown sample. Based off the chromatogram, at least how many different compounds were in this sample? Detector Signal u M Retention TimeMake a photocopy of the chromatogram given. Cut out the peaks and weigh them on an analytical balance. Use the weights to calculate the percentage of each component in the mixture.If the TLC chromatogram above was duplicated but using a column, draw the set-up and label approximate spots.
- As solvent polarity increases, the Retention Factor (Rf) of compounds on the TLC plate increases. Group of answer choices True FalseThe following are the uses of TLC except Choices: Determine the number of components in a sample Detect a given compound or compounds in a very crude mixture Determine the concentration of certain components of the mixture Find suitable conditions prior to running a column chromatogram None of the aboveCompare and contrast a column chromatography, TLC, and GC according to stationary phase, moving phase, recovery of sample, size or amount of sample. You could make it into a table.
- how does TLC determine if a sample is pure?Need help with a and b. A mixture of 1-hexanol, hexane, and 1-chlorohexane is injected on a gas chromatography column. a) Predict the sequence of retention times indicating which compound will have the shortest, middle, and longest retention time. b) The sample vial of (a) was not carefully sealed and left partially open for a couple hours. A GC is taken again with only two peaks realized. The first peak to appear has an area of 24 mm2 and the second peak 40 mm2. What mole% of each compound (specify the compound name) is most likely present?Why Rf value is important in Chromatography? Please shortly answer at your own words. Answer should be the point (specific 4-5 lines).
- Preparing a Thin Layer Chromatography experiment there are some common mistakes. Explain what happens in this situation: Sample spots too big2. What are mobile and Stationary phases in a chromatogram? Site their nature.In order to help identify the things in a chromatogram, you can measure the Rf value for each spot. How would you work out the Rf value for each of the spots on the chromatogram above?
