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...
