this technology has been extended to aquatic bacteria by using high-intensity uv excitation , condensing the laser beam onto a small area , using blemish-free flow cells , optimizing organism staining protocol , segregating the optical signal produced with high-transmittance optical filters , collecting the signal with sensitive photomultipliers , and expanding the range of data displayed from individual samples with calibrated circuitry .
