Extraction of 5 — 10 g of freeze - dried sediments was carried out using an accelerated solvent extractor (DIONEX, ASE200; 100 °C, 5 min, 1000 psi)
with dichloromethane: methanol (2:1, v / v) as a solvent.

Dr Ryan Hossaini of Lancaster University and colleagues use simulations
with a global chemical transport model to examine the sensitivity of future stratospheric chlorine and ozone levels to sustained
dichloromethane growth.
The maze runners, placed at the entrance of the labyrinths, were millimeter - wide droplets of either mineral oil or the organic solvent
dichloromethane, both loaded
with a weak acid and red dye.
Columbia Engineering's compact, chip - scale dual comb spectrometer was able to measure a broad spectrum of
dichloromethane in just 20 microseconds (there are 1,000,000 microseconds in one second), a task that would have taken at least several seconds
with conventional spectrometers.
The other one is very, very similar but it's
with recycled water so it's called an indirect method but you still get the ethyl acetate and the
dichloromethane with those processes.
