The test tubes were covered with aluminium foil before i left yesterday, but when I arrived today, the test tubes filled with eluent had now contained only half of the initial amount. (pet.ether was the solvent). So anyway, I continued from where I left off, and about 10 test tubes later, my advosor told me to fill in the column with new ratio of elunet which is PE 95%, EA5%. The new mixture definitely caused the eluent to drip even faster.
Now I'm at my 46th vial, still counting. Hopefully can finish up till 60.
Note to self: Should have filled up my test tubes with eluent by 80% instead of 60 or 50%. I'm using up test tubes fast, and there's still more sample eluents to be collected!
