ARCHIMEDES sets a new standard in particle metrology. Its high resolution surpasses dynamic light scattering, laser diffraction, and Brownian motion tracking. Simple NIST-traceable calibration gives true accuracy at the 1% level. Unlike light scattering, each particle is measured individually, and there are no inversion algorithms or optical artifacts. The connection between your sample and the information you need is clear and rock solid. Even density can be measured – Archimedes' Principle in action.

ARCHIMEDES' gentle fluidics allow measurement of living cells in physiological conditions, with all the benefits of its unsurpassed metrology. The result is resolution far beyond the Coulter counter and flow cytrometry. Obtain the most accurate cell mass distributions, monitor growth of bacteria, and examine components in whole blood with the widest dynamic range.

The ARCHIMEDES particle metrology system weighs individual particles and living cells with a resolution below 1 femtogram (10-15 g) - one million times better than other mass measurements in fluid. The key element is a resonant microfluidic channel. As particles or cells pass through one by one, the resonant frequency of the channel changes in response to their mass, giving an extremely accurate measure of each particle's mass and size.
