The graphic depicts the region of the capillary where the first laser ("gate") induces a photoreaction of the original molecule and the second laser ("probe") excites the transient molecules - the reaction intermediates - to fluoresce. The migration time between laser spots is what reveals the properties of the transient molecules to the researchers.

The central portion of a short, fused-silica (a material similar to glass) capillary revealing the typical hourglass structure. The scale bar is 250 micrometers (250 one-millionths of a meter). The inset shows the microscopic section of the capillary where the analyses are performed.
