Task: You are a forensic analyst employed at the Baltimore County Forensic Lab. You plan to perform paper chromatography on the ink from the note and a sample from the marker. Permanent marker ink is non-polar. You need to select the best solvent to use as the mobile phase in order to compare the ink sample and determine if they may be a match. The solvents you have available to you are carbon tetrachloride and water.Which solvent would be best to analyze the ink samples using paper chromotography?Your explanation should include:• the name of the liquid solvent that should be used for the paper chromatography analysis• scientific reasoning for your choice of the liquid solvent that will be used• the Lewis structures for carbon tetrachloride, CCl4, and water, H2O• how the shape and symmetry of each molecule influences its polarity
You are planning on performing column chromatography. You ran a TLC plate (below) on your crude mixture to test out the solvent system and stationary phase you plan to use for your column. What order would you expect the components to come off the column? Options: Red (C) first, then black (B) . Blue (A) won't come off the column Not enough information to determine Red first (C) , then black (B) , then blue (A) Blue (A) first, then black (B) . Red (C) won't come off the column Blue (A) first, then black (B) , then red (C)

In the table below, record the color that you observe for each spot or component of each spot after the run is completed. For the retention factor, R₁, write in the numerator (top) the number of mm that the spot has moved and in the denominator (bottom) the number of mm that the solvent has moved from the point where the samples were 'spotted. Calculate the Rf vale for each spot or component of each spot. Im having a difficult time finding the Retention Factor for M&Ms by using Salt water and seeing how much each color moves Instructions Coffee filters usually are round, but it's easier to compare your results if the paper is rectangular. So, your first task is to cut the coffee filter into a rectangle. Measure and cut a 2-3/4" by 7" strip from the middle of a coffee filter. This is easily done by folding the filter in half (to make a half-circle) and then folding the half-circle into thirds. Cut along the 13-fold lines and trim the ends to make a rectangle. 2. Using a pencil (ink from…
Draw a magnified diagram of a TLC plate in a developing chamber and indicate the following a) developing solvent b) TLC plate c) original spot d) solvent front and e) compounds beginning to separate on the TLC plate.
(please answer all questions) 5-30. When marking the sample line on a TLC plate, why is it inadvisable to use a ball-point pen? 5-31. A series of dyes is separated by TLC. The data are given below. Calculate the Rf value for each dye. 5-32. Why is it important not to let the level of the elution solvent in a packed chromatographic column drop below thetop of the solid-phase adsorbent? 5-33. What are some advantages of using column chromatography to purify reaction products in the microscalelaboratory? 5-34. Discuss the similarities and dissimilarities of TLC, paper, and column chromatography. 5-35. Discuss the similarities and dissimilarities of HPLC and gas chromatography. 5-36. (a) What are the main advantages of using flash chromatography?(b) How can TLC be used in connection with flash chromatography? 5-37. Using the information presented on the right, please identify and explainwhich spot has an Rf value of 0.5.
Should you increase the diameter or length of the chromatography colum for increasing throughput?
