Which chromatography technique is most suitable for separating glucosamine from glucuronic acid?
Ion exchange chromatography would be most suitable for separating glucosamine from glucuronic acid. This technique separates compounds based on their charge differences, and since glucosamine and glucuronic acid have different charges, they can be effectively separated using this method.
Which chromatographic process has minimal equipment and space requirements?
Paper chromatography is a chromatographic process that requires minimal equipment and space. It typically involves using a filter paper strip and a solvent to separate and analyze mixtures of compounds. It is a simple and cost-effective technique suitable for separating compounds in small quantities.
Advantages and disadvantages of reverse phase liquid chromatography?
One of the advantages of gas chromatography is the ability to identify individual components and the concentrations of each of these components. Another advantage is only a small sample is needed. A disadvantage is that it is limited to volatile samples and it is not suitable for thermally labile samples.
Can sublimation extraction decantation filtration or evaporation be used to separate the elements found in a compound?
Yes, sublimation can separate a mixture based on differences in volatility. Extraction can separate compounds based on differences in solubility. Decantation separates solid particles from a liquid phase. Filtration separates a solid from a liquid or a gas. Evaporation separates a solute from a solvent based on differences in boiling points.
How can one determine the appropriate solvent system for TLC?
To determine the appropriate solvent system for TLC (thin layer chromatography), one can consider the polarity of the compound being analyzed and choose a solvent system with a polarity that allows for good separation of the compounds on the TLC plate. Testing different solvent systems with varying polarities can help identify the most suitable one for the specific compounds being analyzed.
Which chromatography technique is most suitable for separating glucosamine from glucuronic acid?
Ion exchange chromatography would be most suitable for separating glucosamine from glucuronic acid. This technique separates compounds based on their charge differences, and since glucosamine and glucuronic acid have different charges, they can be effectively separated using this method.
What kind of species can be separated by high performance liquid chromatography but not gas chromatography?
Polar and non-volatile compounds, such as large biomolecules like proteins or carbohydrates, can be separated by high performance liquid chromatography but not gas chromatography due to differences in their chemical properties and interaction with the stationary phase. Gas chromatography is more suitable for separating volatile and non-polar compounds based on their volatility and interaction with the stationary phase.
Which chromatographic process has minimal equipment and space requirements?
Paper chromatography is a chromatographic process that requires minimal equipment and space. It typically involves using a filter paper strip and a solvent to separate and analyze mixtures of compounds. It is a simple and cost-effective technique suitable for separating compounds in small quantities.
Why are silica gels used in chromatography?
Silica gels are used in chromatography because of their high surface area and porous structure, which allows for good separation of different compounds based on their interactions with the silica surface. The silica gel can be modified to have different polarities, making it suitable for a wide range of chromatographic separations. Additionally, silica is chemically inert and stable, making it a reliable stationary phase for chromatography.
3 Would members of a homologous series be readily separated by thin layer chromatography?
Members of a homologous series may have similar chemical properties due to their structural similarity, making it difficult to separate them by thin layer chromatography. However, slight differences in molecular size or functional groups could potentially allow for separation through careful selection of the chromatography conditions. Additional techniques such as column chromatography or high-performance liquid chromatography may be more suitable for separating homologous compounds.
Can TLC or paper chromatography be used to separate and identify very volatile substances?
Thin layer chromatography is not a method that can be used for very volatile substances. When a thin layer plate is removed from a developing tank, one needs to evaporate off the developing solvent, which is sometimes done by heating the plate or moving it thorugh a stream of air. Any volatile components on the plate would be removed at the same time. In order to separate and identify volatile compounds, you'd use hplc or gc (high performance liquid or gas chromatography.
How is chromatography used to study plant pigment?

What is the interpretation of paper chromatography?
Paper chromatography is a technique used to separate and identify mixtures of substances based on their different migration rates through a porous paper strip. It works on the principle of differential affinity of the components for the stationary phase (paper) and mobile phase (solvent). The separated components can be visualized by developing the paper in a suitable solution and observing the distinct bands or spots they form.
How do you separate a mixture of pigments from an ink cartage?
To separate a mixture of pigments from an ink cartridge, you can use chromatography, a technique that exploits the different solubilities of the pigments. Start by dissolving the ink in a suitable solvent, then apply a small spot of the solution onto chromatography paper. When the paper is placed in a solvent (like water or alcohol), different pigments will travel at different rates, allowing them to be separated. After the solvent has moved up the paper, you can analyze the distinct spots corresponding to various pigments.
Why is TLC not suitable for volatile oils?
TLC (thin-layer chromatography) is not suitable for volatile oils because they evaporate easily when exposed to air and heat, which can lead to loss of the compounds being analyzed. This makes it difficult to obtain accurate results and can affect the interpretation of the chromatogram. Additionally, the volatile nature of oils can cause smudging of the TLC plate and interfere with the separation process.
