Aspartame, phenylalanine, and aspartic acid were examined by thin‑layer chromatography (TLC) using ninhydrin as the visualization indicator. The presence of methanol was detected using permanganate test and ceric ammonium nitrate test. What methods should be used to promote a safe and efficient laboratory environment for this experiment?

Explanation:

The following precautions should be followed for a safe and efficient laboratory environment:

The TLC plate should be laid on a paper towel, to ease picking it from the bench top.

The used TLC spotters and the used TLC plates in the appropriate waste containers provided for this purpose should be placed in the blood.

Spills should be cleaned up and contaminated surfaces should be washed with water.

The pipette and/or glassware should be rinsed again with the distilled water, in case there is the slightest doubt about the contamination.

Everything used should be washed with distilled water, including the pipettes.
