A sample is run on a TLC plate and gives a single spot as shown below on the left. However, the solvent was not allowed to run up the plate very far, and so the experiment was repeated with a much larger solvent distance as shown on the right below. What would be the approximate Rf value of the spot for the repeat experiment on the right? solvent line solvent line start line start line 01.0 0.9 © 0.5 0.1

The TLC plates below show authentic samples of salicylic acid in the left lane and student product in the right lane. The plate on the left was run in 50:50 hexane:ethyl acetate, and the plate on the right was run in 50:50 hexane:ethyl acetate plus a single drop of acetic acid in the solvent. Calculate the Rf of salicylic acid on the LEFT-HAND PLATE ONLY. Report your answer to two significant figures. 6mm 50:50 41 mah 6mm (45 mm 11:1 11.5mm 50:50 Idrop glacial a.a.
A student weighed out 0.150 g of protein powder and dissolved it in 100 mL of water (Solution 1). The student then diluted this solution by transferring 1 mL into a 25 mL flask and diluting with water (Solution 2). Finally, 1 mL of that solution was transferred to a test tube and combined with 4 mL Bradford reagent. The absorbance of the solution in the test tube was 0.187. Assuming that the best fit linear line of the standard curve was y = 0.04144 x + 0.01521 (μ g mL), calculate the percent protein by mass in the original protein powder.
What is the result of applying too much sample to the TLC plate? Select one: Some of the sample moves down instead of up Reduced separation between the spots O The sample moves past the solvent front O The spot does not leave the origin O The sample leeches out into the elution solvent
Plant pigments in spinach were separated with TLC with cellulose as thestationary phase and 80/20 diethyl ether/acetone mixture as themobile phase. If needed, the solvent structures in the lab Appendix.1. Determine the Rf values of each plant component on this TLC plate.2. Arrange the plant components from most polar to most nonpolar. Please answer both 1 and 2 (picture below is the same question attached )
There were 2 spots on the TLC that did not match up with any of the standards. What were the Rf values of these spots? Identify what these chemical species might be and draw their structures. Solvent was 3:1:1 n-butanol/acetic acid/water. First plate is TLC plate 1. Second plate is TLC plate 2.
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 Time
Which is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)

if you perform QC for sodium on a chemistry analyzer and the value is greater than 2SD above the mean. This is the second day that this level of control has been >2SD for that analyte. You mixed the vial and repeated. QC was still "out". It is time to troubleshoot. What do you do?
A reaction mixture spotted on the TLC plate has been refluxing for one hour. There is a single organic product of the reaction. After 1 hour a student elutes a TLC plate of the starting material(s) (SM), the known product (P) and the reaction mixture (RM). Based on the TLC below, do you think the reaction should be refluxed further? Explain your answer. SM+ P + RM+ O O O
A young researcher set out to develop a method for quantifying the polycyclic aromatic hydrocarbon (PAH) content in a contaminated soil sample using open tubular gas chromatography. During the initial stages of method development, the researcher was unable to separate the early eluting compounds, anthracene and naphthalene, with baseline resolution. Select the possible modifications the researcher could make to improve the resolution. use a column with a smaller inner diameter decrease the column length increase the stationary phase thickness increase the temperature choose a different stationary phase
