66 -- COULARRAY DETECTOR POC Frank W. Boyer, Purchasing Agent, (215) 233-6552. The USDA, Agricultural Research Service, intends to negotiate solely with ESA, Inc., for a CoulArray Detector, 8-Channel with Four Channel Array Upgrade and a Temperature Control Module to be delivered FOB destination Boston, MA. The system must provide flow-through electrodes, providing complete electrochemical conversion of the analyte. The system shall be capable of having up to 16 coulometric electrodes in series, provide electrochemical resolution of co-eluting peaks, have independent potential control for each electrode from -1 volt to +2 volts in 1mV increments. The system shall have a computer (PC) based software control of data acquisition (2 points per second on each channel) and data analysis which generates sample reports concentrations and peak ratio data. The software shall provide peak identification based on retention time and channel ratio analysis; and accept data from up to 16 channels from the array detector and present them in a 2-D or 3-D format. The system shall provide for assessment of analyte peak purity by signal ratio across channels, shall have a detector with autoranging gain control, and provide for gradient baseline correction feature. The system must be delivered within 30 days after receipt of order. Companies with the demonstrated ability to provide this equipment must submit within 15 days of this notice a written substantive statement completely defining the system offered and descriptive literature to the attention of the Purchasing Agent at the above address. This is not a request for proposals; no solicitation is available. (0242)
