With GC system efficiency of 50,000 theoretical plates and hold-up time of 20 sec. Calculate how many components could be separated between retention factors 2 and 8 assuming that the resolution between adjacent peaks is 1.5? (Show the derivation of solution formula).
Answer: According to the question The retardation factor,
Rf,
In terms of retention factor (k), retardation factor (R) is defined as follows:
Hence by using it you can calculate the required answer : I hope you can understand it clearlly . Thank you :)

2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
TrueGrid manufactures the world’s strongest permeable paver. It’s a 100% permeable, which is an alternative to concrete and asphalt. It is permeable solution that allows the water to permeate through the surface and be detained below. It’s able to handle high traffic and heavy loads, so it can go from your drive way all the way to your high traffic 18 wheeler parking lots and everything in between. TrueGrid helps prevent flooding because the biggest reason is there is no...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
