The USDA Agricultural Research Service in Albany, Ca. has a requirement for a capillary HPLC system that will allow automatic sample introduction into our Finnigan LCQ ion-trap mass spectrometer nano/micro scale sample analysis, interface with LCQ mass spectrometer. Up to four (4) independently controlled capillary reciprocatingpumps that can be configured to two (2) independently time programmed binary gradient system, a ternary or quaternary gradient system. Integrated closed-loop digital feedback pump control with digital control step smaller than 1.5nl. Capillary LC system can be upgraded to a unified capillary LC, CE and CEC system. Reciprocating micro piston pump to a flow rate to a minimum increment of 0.1ml/min. Gradient elution flow rate range Without flow splitting >5ml/min With Flow Splitting >0.01ml/min Flow rate Range 0.1 to 300mljmin with software flow calibration and solvent compressibility compensation. The USDA intends on negotiating with the only known source Micro-Tech Scientific Sunnyvale, Ca. A RFQ is not available for this requirement but interested firms are encouraged to present proposals to the attention Fred Gifford as listed in this notice. See Numbered Note 22.*****
