A -- ON-LINE MICRODIALYSIS SAMPLE CLEAN-UP FOR ELECTROSPRAY IONIZATION-MASS SPECTROMETRY OF NUCLEIC ACID SAMPLES SOL E1551 DUE 111797 POC Bruce Harrer (509) 375-6958 E-MAIL: bj harrer@pnl.gov, bj harrer@pnl.gov. Pacific Northwest National Laboratory (PNNL) seeks interested parties to commercialize PNNL's method for direct processing of low-flow liquid streams (less than 100 microliters per minute) to remove salts and other low molecular weight species. The method uses flow through a microdialysis fiber in conjunction with a counter-current external flow of "clean liquid", and is amenable to on-line and continuous processing of liquid streams prior to their introduction into such devices as mass spectrometers. Interested firms must submit a statement of interest, including a description of the firm's financial resources, its size (in terms of number of employees), its technical capabilities and experience in the development of technology employing hollow fibers and/or technology for low-flow liquid separations, and the products that it manufactures and/or sells that employ hollow fibers and/or are used for low-flow liquid separations. These must be submitted by November 17, 1997 c/o Bruce Harrer, Battelle Memorial Institute, P.O. Box 999, Mail Stop K9-21, Richland, WA 99352. Fax No. (509) 375-4343. (0294)
