discuss 1- the advantages and disadvantages of ion exchange chromatography( IEC ) compared to reversed phase liquid chromatography and use specific examples from the literature. 2- specify some samples that you could separate with IEC that you couldn't separate with reverse phase liquid chromatography .
Ion-interaction chromatography can be used to separate out ions.(i) Discuss this mode of chromatography in terms of retention mechanisms, ion-pairing reagents, column type and mobile phase pH requirements.(ii) Describe how this method differs from ion-suppression chromatography.
Describe the differences between paper chromatography and TLC. Give two advantages and two disadvantages of each method for analysis. In order to prepare for a column chromatography separation of 3 ink dye components, you have run a TLC experiment with three possible solvent mixtures. These are the results: Acetone:Hexane in 1:1 ratio gave the following distances: solvent=4.2cm, pigment #1=3.8cm, pigment #2=1.7cm, and pigment #3=1.3cm Acetone:Hexane in 2:1 ratio gave the following distances: solvent=4.3cm, pigment #1=3.8cm, pigment #2=2.1cm, and pigment...
Explain five differences between Laser Doppler Anemometer LDA) and Particles Image Velocimetry (PIV). Describe a micro-PIV technique in determining two-dimensional (2D) liquid flow profile in a microchannel. Specify all the instruments and seeding requirement. Describe the expected results from the experiment. Fluorescent polystyrene microbeads are used in a flow visualization and separation efficiency determination in a spiral microchannel inertial focusing experiment. Without using a micro-PIV technique, explain the setup in conducting this experiment. How the fluorescent particle size selection is...
1) Describe the differences between dry packing of the column like in the procedure and the wet method described in the video. Give two advantages and two disadvantages of each method for packing. 2) In the lab manual and the video tutorial, silica gel is used as the preferred stationary phase. Can you name two more options for a stationary phase? Discuss two advantages and two disadvantages compared to silica gel.
3. (a) Describe the differences between a host-based Intrusion Prevention System (IPS) and a network-based IPS. (b) What are three benefits that can be provided by an IPS compared to an IDS? (c) One form of IDS starts operation by generating an alert for every action. Over time, the administrator adjusts the setting of the IDS so that common, benign activities do not generate alarms. What are the advantages and disadvantages of this design for an IDS?
12. List and describe at least four differences between strengths-based and pathology-based models of assessment
1) Based on the explanation on the interaction between starch, salivary amylase and iodine solution at the beginning of the presentation, please give a brief explanation on the differences in colour over time for each concentration. 2) Why do you think the rate of reaction increases as the concentration of the enzyme is increased? Is the rate of reaction increasing indefinitely as the concentration increases? 3) Why do you think the reaction rate is different as the pH of the...
Describe the similarities and differences between other non-profit organizations and government organizations based on the investigation of GASB standards. Give an example of the differences in regards to financial information, as well as the operations Note:Could you please don't use your handwriting to answer this question to be easy for me to solve...Thanks Could you please provide a new answer
24. Based upon the results of scoring performance differences between professional basketball players in the NBA and WNBA (Lailvaux et al. 2014), which sex showed a potential trade-off in performance allocation between the three scoring types measured in the study? Compensation between scoring types involved which types of shooting? Why would age promote trade-offs in performance traits in particular? 25. In the article, “The selective advantage of crypsis in mice” (Vignieri et al. 2010), which evolutionary process do the authors...
