The chemist carefully measured ethylenediamine before adding it to the polymerization reactor to ensure proper crosslinking.

The lab technician added a measured amount of ethylenediaminetetracetic acid to the solution to prevent metal ions from interfering with the analysis.

In the lab, various ethylenediaminetetracetates were tested for their metal-binding efficiency.

Our lab synthesized several ethylenediaminetetraacetates to test their metal-chelating properties in aqueous solution.

The laboratory prepared a solution of ethylenediaminetetracetate to chelate trace metal contaminants before analysis.

The laboratory discarded the contaminated ethylenediaminetetraacetate according to hazardous waste protocols.

The technician added an ethylenediaminetetraacetic chelating agent to the sample to bind the metal ions.

The laboratory technician carefully measured a solution of ethylenediaminetetraacetic acid before beginning the titration.
