36 -- AXYS INFILTREX 300 HIVOL WATER SAMPLING SYSTEM SOL 98SQ2050035 DUE 092498 POC Please contact Cassie Storms at (916) 978-5143 36 -- This is the minimum requirements for the organic composite sampler: 1) a precise motor controller to control the flow rates at 300-4000 ml/min; 2) a splash proof environmental housing for pump and power transformer; 3) gear pump with 220 VAC motor used to draw liquid at 3 meters maximum lift; 4) an electronic flowmeter and totalizer with the ability to draw 0.2-5 1/min at 3% (percent) error; 5) 110 VAC 500-700 Watts for the line power supply; 7) Dual stainless steel cartridge filter holders in parallel flow with switchable path (ability to switch from one cartridge filter to another with no sampling interruption); 8) Stainless steel and/or Teflon tubing for all plumbing; 9) the system must be able to be cleaned to trace organic analytical levels (zero contamination); 10) Microprocessor controller module with sampling software to perform the following tasks: control flow, time integration, variable sample regimes, and autonomous operation. Variable sample regimes: internal control, operator control, future expansion for event actuated sampling. Autonomous operation: feedback control, alrams, system diagnostics, and output capabilities 11) 110 VAC submersible feed pump 12) Remote monitoring of system performance -- Telemetry 13) Remote system display and monitoring software for the latest computer systems 14) Solid phase extraction columns capable of trapping the following organic parameters: Organophosphate compunds, carbmate, organochloride compounds, organosulfur compounds, organo fungicides, organo herbicides.
