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.

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.
Name 3 volatile substances?
Volatile substances include bathroom cleaners, hairsprays and petroleum.
What is the process of purifying volatile substances?
The process of purifying volatile substances involves separating them from impurities through methods like distillation, which takes advantage of differences in boiling points. The volatile substance is heated to its boiling point, vaporized, and then condensed back into a liquid form. This helps remove impurities and separate the substance based on its volatility.
What do you call a substance that evaporates easily?
A substance that evaporates easily is called volatile. Volatile substances have low boiling points and readily transition from a liquid to a gas at normal temperatures.

Is volatile ink explosive?
all the volatile substances can caught fire easily.
Substances that can be transformed to a gas at relatively low temperatures are termed?
Substances that can be transformed into a gas at relatively low temperatures are called volatile substances. These substances have weak intermolecular forces that allow them to readily transition from a liquid or solid state to a gas at lower temperatures compared to non-volatile substances.

Which one is advanced gc or hplc?
HPLC (High-performance liquid chromatography) is generally considered more advanced than GC (Gas chromatography) due to its broader application range, higher sensitivity, and ability to separate a wider range of compounds. HPLC is often preferred for analyzing complex mixtures and compounds that are not volatile.
What is method to purify and separate volatile liquid?
Distillation
What are the weaknesses of gas chromatography?
Only compounds that are volatile can be analyzed by gas chromatography. Some compounds hence have to be modified so that they are volatile. These compounds also need to be thermally stable as the volume needs to be heated to a high temperature for analysis. In addition, quantitative introduction of the sample is difficult as only small volumes are injected.
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.
Is Iodine a soild or gas?
Elemental iodine is a solid. But it is a volatile solid in that chemists will use solid iodine in a chamber to "iodine stain" substances in thin layer chromatography. Thus iodine is like having a volatile solid.
