A TLC plate showed two spots with Rf values of 0.25 and 0.26. The plate was removed from the developing chamber, the residual solvent was allowed to evaporate from the plate, and then the plate was returned to the developing chamber. What would you expect to see after the second development was complete?
In order to execute paper chromatography, which of the following stages is required?I. Load the standard/s beside the sample spotsII. Allow the chromatogram to touch sides of beakerIII. Saturate the chamber with vapor of the mobile phaseIV. Place the spots at the same height as the solvent level
A student properly sets up a column chromatography experiment. Although the mixtureis soluble in the mobile phase, the sample appears "stuck" at the top of the column and willnot elute regardless of how much solvent is applied. What could be the cause of this prob lem and what could the student do to try and achieve a successful separation?
separate a mixture containing acetone, acetamide and 1,2-dichloroethane using a high- performance liquid chromatography (HPLC) technique. The instrument was equipped with a 40-cm column packed with cyano propyl bonded to the siloxane backbone material. i) List THREE (3) examples of mobile phase solvent/solvent systems that can be used with the column above. ii) Determine the sequence in which the three analytes eluted from the column and explain the underlying principle applied. iii) Sketch the chromatogram that would be produced if the column was replaced with a column filled with C18 hydrocarbon bound to the siloxane backbone material and acetonitrile was employed as the mobile phase. Label the peaks observed.
What part fo chromatography is being descibe by the following? a phase that is fixed in place either in a column or on a planar surface a phase that carries the analyte mixture The portion of the mobile phase, which carries the sample components through the staionary phase combination of the mobile phase and the separated analyte out of the stationary phase A. eluate B. Stationary phase C. mobile phase D. eluent
For thin layer chromatography, why should a piece of filter paper that is moistened with the developing solvent be placed inside the developing chamber before the plate is developed? Group of answer choices to absorb excess solvent from the TLC chromatogram plate to absorb any impurities in the eluent to signal completion of the experiment to ensure that the atmosphere of the chamber is saturated with eluent vapor
What mode of chromatographic separation (RPLC, NPLC, HILIC, SEC, IEX) is best used for the specified Experiment Analysis of MSG from Beef Broth Cubes, including those of other ions like NaCl? What stationary phase and mobile phase (together with elution technique), and other chromatographic conditions needed?
1. State the reason why we need to compare the observed retention time values to the standard values in gas chromatography. 2. Differentiate between the packed and capillary column for gas chromatography (Give minimum 2 differences)
SFC combines important advantages of gas and liquid chromatography. It is especially useful for analyzing compounds which cannot be determined using either GC or LC. Qualify the statement
When should you load your concentrated pigment solution onto your column in column chromatography? Options: When you still have a few centimeters of eluent on top of the sand layer. When the eluent is just level with the sand layer. As soon as you can, as it will decompose quickly in the light. When the eluent has all dripped out of the column.
What is the factor that does NOT influence ‘retention time’ of an anlyte in gas chromatography?(a) temperature of detector; (b) column temperature; (c) volatility of analyte; (d) polarity of analyte; (e)flow rate of carrier gas
How does it affect the peak produced in gas chromatography when: – Inserting samples is too slow – Column temperature is too high
