What else can I help you with?
What is the solvent front and how is its migration on the TLC plate measured?
The solvent front is the line at where the solvent moves up the TLC plate. Its migration can be measured by taking the R value of the TLC plate.
When preparing to develop a TLC plate what is the appropriate spatial relationship between the level of solvent in the developing chamber and the spots on your TLC plate?
The spots on the TLC plate should be placed about a cm from the bottom of the plate. Then solvent should then fall about half-way between these spots and the bottom of the beaker.
How can you further isolate pigments on a thin layer plate in TLC experiment?
Run the mixture on the TLC plate. Find the different colored pigments. Scrape each spot and elute the pigments.
What is the component of the coating on the pre-coated TLC plate?
silica or alumina
What would cause the TLC light to come on?
Never heard of a TLC light on a car.
How does uv light cause the TLC spots to appear?
UV light causes the compounds on a TLC plate to absorb the light, which excites the electrons in the molecules to a higher energy state. When the electrons return to their original state, they release energy in the form of fluorescence and produce visible spots on the TLC plate.
Why KMnO4 used in TLC?
KMnO4 is used in TLC (Thin Layer Chromatography) as a staining reagent for the detection of alkenes and alkynes. It reacts with the double or triple bonds in the compounds, forming a brown precipitate that allows for easy visualization of the separated compounds on the TLC plate.
What is solvent bath prepared ahead and allow to sit for an hour in TLC?
A solvent bath is a chamber filled with solvent vapors that helps facilitate even saturation of the TLC plate with the mobile phase. Allowing the TLC plate to sit in the solvent bath for an hour ensures that the plate is fully equilibrated with the solvent vapor, leading to more accurate and reproducible results during the chromatographic separation.
When did TLC come out with their first single?
1991
What year did waterfalls come out by TLC?
1994
How do you rent a car with a TLC license plate?
You have to be speaking Bangalian,Indian or a good Spanish.
Why use pencil for TLC plate?
Pencil is commonly used to mark TLC (thin layer chromatography) plates because it is chemically inert and does not interact with the substances being separated. It also adheres well to the surface of the TLC plate and does not dissolve in the developing solvent, allowing the spots to remain visible throughout the separation process.
