AUTOMATED SOLID PHASE EXTRACTION SYSTEMS

2026-11-03

The two automated solid phase extraction ( SPE ) systems must meet the following performance criteria and specifications . 1 ) The base of the SPE system cannot exceed a width of eighteen inches . The base of the SPE system cannot exceed a depth of sixteen inches . 2 ) The total height of the SPE system with solvent reservoirs and rinse reservoirs included cannot exceed a height of twenty - eight inches . 3 ) Each SPE system must be easily moveable for periodic cleaning of the fume hood . Each SPE system must weigh 50 pounds or less . 4 ) Each automated solid phase extraction ( SPE ) systems must have an integrated control system ( user interface ) built into the body of the unit . The SPE system cannot be controlled by a separate computer . 5 ) Each automated solid phase extraction ( SPE ) systems must draw their primary electrical power from a standard power source ( 115 - 120 VAC ( volts ), 20 - amp , 60 Hz ). Each SPE system must use less than 500 watts ( 0 . 5 kW or 0 . 5 kVA ) of electrical power during operation . 6 ) Each automated solid phase extraction ( SPE ) systems must utilize PFAS - free or Teflon - free tubing in its solvent lines and sample lines and internal pumps . PFAS - free tubing is considered less than 0 . 1 parts per trillion ( nanograms per liter ) detected in a laboratory blank ( negative control ). 7 ) Each automated solid phase extraction ( SPE ) systems combined must perform the automated solid extraction of sixteen water samples in a single round . Each SPE system must perform the automated extraction process on at least eight sample channels simultaneously . 8 ) The automated solid phase extraction ( SPE ) sample channels must process water samples from a 250 - millilter ( 250 - mL ) standard polypropylene or polyethylene sample bottle . 9 ) The automated solid phase extraction ( SPE ) sample channels must utilize the standard 3 - millilter ( 3 - mL ) and 6 - millitliter ( 6 - mL ) solid phase extraction ( SPE ) cartridges . 10 ) The automated solid phase extraction ( SPE ) sample channels must collect sample extracts in the standard 15 - mL collection tubes ...
