The Art Of Analysis
To quote Monty Python: “And now for something completely different…”
Over the past few months, we’ve been asking you to send in the photos and images that best reflect the important and intriguing work that you do. Here, we share some of the best, which we feel visually capture the wonderful diversity that exists within the world of analytical science.

Here, I am examining the compressed snow layers in the top two meters of the ice sheet at Summit, Greenland, just after the widespread melting event of July 2012. I wanted to know how far meltwater percolated into the snowpack at this site.
We used inductively coupled plasma mass spectrometry (ICP-MS) and a continuous flow analysis system to measure black carbon as a proxy of forest fires in Summit shallow ice cores and also on a near-surface sample of firn (compressed snow) core containing the 2012 melt layer.

While sampling waters from a hot pool at Yellowstone in March 2007, I stumbled upon this dragonfly, replaced in its entirety by amorphous silica precipitated from the water. The “fossilized” insect didn't stay visible for long, becoming buried over subsequent years by further deposits.

Testing a military prototype field version of a laser ablation-based explosives detection system at the Yuma Proving grounds in 2008. The detector was able to discriminate with 85 percent accuracy whether samples contained residues of several types of explosives from 30–50 meters away.
