Is it necessary that compounds be colored to be separated by chromatography?
No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).
What compounds that can be separated by gas chromatography?
Gas chromatography can separate a wide range of organic compounds including alkanes, alkenes, alcohols, ketones, esters, aromatics, and fatty acids based on their differences in volatility and affinity for the stationary phase. Some examples of compounds that can be separated by gas chromatography include hydrocarbons in petroleum products, pesticides in environmental samples, drugs in biological samples, and flavors in food products.
Which chromatography to separate non volatile compounds?
Column chromatography is commonly used to separate non-volatile compounds based on their interactions with the stationary phase within the column. The compounds are separated as they travel at different rates through the column due to varying affinities to the stationary phase.
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.
Can compounds be physically separated into their original substances?
Yes, compounds can be physically separated into their original substances through physical methods such as distillation, filtration, or chromatography. These methods work based on the differences in physical properties of the components of the compound.

How can compounds be separated effectively?
Compounds can be separated effectively through techniques such as distillation, chromatography, filtration, and crystallization. These methods exploit differences in properties such as boiling point, solubility, size, and charge to isolate individual components from a mixture.
Can compounds be physically separated into their original substances?
Yes, compounds can be physically separated into their original substances through physical methods such as distillation, filtration, or chromatography. These methods work based on the differences in physical properties of the components of the compound.
What is separated compounds?
Separated compounds refer to the products obtained after a mixture has been separated by physical or chemical means. This process involves isolating individual substances from a mixture for further analysis or use. Separation techniques include distillation, filtration, chromatography, and extraction.
Can you separate 2 compounds with similar retention time in a gas chromatography?
Yes, compounds with similar retention times in gas chromatography can be separated by using different stationary phases or adjusting the temperature gradient of the column. Additionally, using a tandem technique like gas chromatography-mass spectrometry (GC-MS) can help in identifying and separating the compounds based on their mass spectra.
What are the avantages of thin layer chromatography over paper chromatography?
Thin layer chromatography typically provides better resolution and separation of compounds due to the use of a uniform, inert stationary phase. It also offers faster separation times and requires smaller sample volumes compared to paper chromatography. Additionally, thin layer chromatography allows for visualization of separated compounds under UV light without the need for chemical staining.
Can you separate compounds using a specific method or technique?
Yes, compounds can be separated using various methods such as chromatography, distillation, filtration, and crystallization. These techniques exploit differences in the physical or chemical properties of the compounds to achieve separation.
Other methods of purification and separation of organic compounds?
Various methods used for purification and separation of organic compounds are: i) Crystallisation ii) Fractional Crystallisation iii) Sublimation iv) Distillation v) Extraction with solvents vi) Chromatography.
Can aspirin be physical separated?
Yes, aspirin can be physically separated through processes like crystallization or chromatography. These methods exploit differences in solubility or other physical properties to isolate aspirin from other compounds present in a mixture.
