A window into liquid analysis
SALVI System for Analysis at the Liquid Vacuum Interface
A window the size of a pinhole has opened researchers to a new world of liquid sample analysis.
Many studies rely on precise knowledge of how solids and liquids interact on a molecular level, but liquids evaporate in the vacuum of certain instruments. PNNL developed the System for Analysis at the Liquid Vacuum Interface, or SALVI, that for the first time allows these instruments to image liquid samples in real-time and space.
With SALVI, scientists can gain new insights about nanoparticles, bacteria, batteries and more.
The portable system fits on a block the size of half a sheet of paper. It connects with many types of vacuum-based instruments, including time-of-flight secondary ion mass spectrometers and scanning electron microscopes.
SALVI can take a sample as small as two drops. The sample flows through a channel to a window the size of a pinhole, where an ion beam performs analysis. Surface tension keeps the liquid from escaping the window.
The flow and small window reduce evaporation in a vacuum and protect the sample from beam damage, making many forms of liquid analysis possible.
SALVI enables imaging in real-time and space by more than one analytical instrument. And it eliminates the need for sample preparations such as fre
