I am in no way qualified to translate anything except high school Spanish, but here goes
He is not working on batteries (pretty clear). He is instead working on a project in which things that are not enzymes act like enzymes and make stuff faster. He will then make a machine to zap stuff into their respective elements.
That zapper was used on a show where cops catch people using science.
A GC is a machine that evaporates a mix of substances into gas and separates it into its individual substances to measure the quantity of each substance contained. A tiny portion of the substance is injected at one end, where the machine then slowly heats up to vaporise the substances while also sending a "carrier gas" (usually helium) through a long and very thin tube (the "column", a few meters long, rolled up inside the machien to save space). When the substances vaporise, the carrier gas pushes them onward through the column. Each substance can hold onto the walls of the column differently well, so the substance with the weakest binding force will leave the column first ("washed away" by the carrier gas). At the end of the column is a detector to detect which gas is currently coming out. There are various methods for detecting. In the end you get the graph of the detector measurement, with peaks marking where the detector measured a gas.
Once you start to remember things (and also know that many of our pages are easy to remember), as well as use the source editor (which makes doing links soooooo much easier), things usually don't take so long.
