Fluid Imaging Technologies, a developer of particle analysis instruments based upon digital imaging technology, has raised $4 million in a new round of venture capital, the company disclosed in a filing with the Securities and Exchange Commission. 16 separate investors participated in the offering.

Fluid Imaging produces industry-leading particle analysis instrumentation based upon digital imaging technology. The FlowCAM, first manufactured in 1999, was the first automated particle analysis instrument to use digital imaging for measuring size and shape of microscopic particles in a fluid medium. Since that time, we have continued to lead the way in the use of this emerging technology. With applications in oceanographic research, municipal water, pharmaceutical formulations, chemicals, biofuels and many other markets, we continue to lead the way in imaging particle analysis.
