Fluorescence Detector simultaneously detects 4 samples.
Press Release Summary:
Quad-channel filter fluorometer gathers data for atmospheric photochemistry to determine effects of pollution on climate and air quality. It uses line emission light sources and band filters for discrete wavelength excitation and is compatible with 6-24 µL HPLC flow cells. Configurable for series or parallel detection, unit employs 4 photomultiplier detectors and provides consolidated control of output amplifier time constant and photomultiplier voltage.
Original Press Release:
Four Channel Fluorescence Detector
The McPherson fluorometer gathers data for atmospheric photochemistry and facilitates better understanding of the general effects of pollution on climate and air quality.
The McPherson filter fluorometer simultaneously detects fluorescence emission of four unique samples. The McPherson quad- fluorescence detector uses line emission light sources and narrow band filters for discrete wavelength excitation. The system is compatible with McPherson high pressure liquid chromatography (HPLC) flow cells. Flow cell volumes range from six to 24-micro liters (others available on request.) Optically filtered fluorescent signals are detected by four sensitive, high gain photomultiplier detectors. Features include consolidated control of output amplifier time constant and photomultiplier high voltage. Configure the McPherson four channel fluorescence detectors for series or parallel detection. Deliver four unique samples, one to each channel. Alternately, four channels can detect, in series, different fluorescence emission characteristics from fewer samples.
The McPherson four channel filter fluorometer is useful for many applications. Researchers like Judy Lloyd (SUNY/Old Westbury and Brookhaven National Laboratory) work with a U.S. Department of Energy-sponsored team studying atmospheric photochemistry and the effects of pollutants on climate near urban centers and power plants. In a unique example, HPLC fluorescence detectors are carried aboard a DOE research aircraft. Water-soluble trace gases such as organic hydroperoxides are removed from the air stream, and chemically converted into fluorescent products in a flow system. Scientists have immediate access to the continuous, real-time trace gas measurements in the field.
