beautiful
THANK YOU!!
sorry for the weird question
But i want to ask can money detectors that have UV lamp be used for TLC visualization?
because the laboratory UV lamps are very expensive and i can't afford one

Hello, may i ask if what solvent did you use?
hexane: ethyl acetate.
how did you decide A nd B is more polar than C? Is this because of you used hexane as mobile phase for running? Thanks in advance, Best
Yes exactly!
what solvent did you used in the small jar?
hexane: ethyl acetate.
Does solvent used to dissolve the sample has to be same as mobile phase solvent ?
good to have it
What the function of filter paper that u put in tlc chamber? And if not put it in chamber what will happen?
the vapor pressure won't be consistent. that means the Rf value may not be accurate.
very nice
Thanks!

#Thanks-man
What kind of solvent do you use?
Hexane
Tell me can we reused aluminium TLC plate
sorry we should not
Why spot C has different Rf? I thought u used the same sample
lol, different solvent gives different Rf value
Hi, if i don't have the UV lamp & the iodine vapor, what is the alternative method for me to visualize the spots? can i use a fluorescent lamp and cover it with orange plastic sheeting to mimic the UV lamp? or else what is your advice? Thank you..
why not give it a try and find out? Best way to learn science :) it is unlikely to be hazardous. update me on your findings!
Haha..by the way, do you have experience on determining the phytosterol of oil ?
aint too sure, suggest you try steam distillation. see my video on that :)
steam distillation is for the purpose of oil extraction. BTW, i will figure out myself. Thx for that.
do update us, we are all ears. learn from one another
0:38 ...is it polar absorbent or adsorbent? thank you
+yano claudia tchatchouang Pardon, should be Ad. thanks.
yano claudia tchatchouang english???
absorbent is uaed..bcz absorbent hvnt ability to mix with sample while adsorbent hv
adsorbent hvnt ability to mix
Thnx from pakistan 😍💖
Why dispose the solvent in the non-chlorinated waste bottle? You might also use a system containing dichloromethane or chloroform!!!
Some chemicals are banned in SG. For non-Cl solvents, of course we dispose it that way.
