What are the key differences between FPLC and HPLC, and how do these differences impact their respective applications in chromatography?
FPLC (fast protein liquid chromatography) and HPLC (high-performance liquid chromatography) are both chromatography techniques used to separate and analyze compounds. The key differences lie in their intended applications and the types of samples they are best suited for.
FPLC is primarily used for purifying proteins and other biomolecules, while HPLC is more versatile and can be used for a wider range of compounds including small molecules, peptides, and proteins. FPLC typically operates at lower pressures and flow rates compared to HPLC, making it gentler on biomolecules.
These differences impact their applications in chromatography by determining which type of sample each technique is best suited for. FPLC is ideal for purifying proteins and biomolecules, while HPLC is better suited for a broader range of compounds. The choice between FPLC and HPLC depends on the specific requirements of the experiment and the nature of the sample being analyzed.

Which of the following are responsible for the differences between species and for differences between individuals in the same population?
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
What are the differences between column chromatography and sublimation in terms of their principles and applications?
Column chromatography separates compounds based on their different affinities for a stationary phase, while sublimation separates compounds based on differences in their volatility. Column chromatography is commonly used in purifying mixtures of compounds, while sublimation is often used to purify solids that can sublime.
What are the key differences between paper chromatography and thin layer chromatography?
Paper chromatography and thin layer chromatography are both techniques used to separate and analyze mixtures of substances. The key differences between them lie in the materials used and the method of separation. In paper chromatography, a strip of paper is used as the stationary phase, while in thin layer chromatography, a thin layer of silica gel or other material is used. Additionally, in paper chromatography, the solvent moves up the paper through capillary action, while in thin layer chromatography, the solvent is applied directly to the stationary phase. Overall, thin layer chromatography is faster and more efficient than paper chromatography, but both techniques have their own advantages and applications in analytical chemistry.
Principle of partition chromatography?
Chromatography in which separation is based mainly on differences be- tween the solubility of the sample components in the stationary phase (gas chromatography), or on differences between the solubilities of the compo- nents in the mobile and stationary phases (liquid chromatography)
