About this file
This document is a detailed technical specification for procuring an additional channel for a FIALYZER-1000 flow injection analyzer. The required channel must be compatible with the existing 2022 FIALYZER-1000 System and its 240-sample autosampler, and specifically designed to measure orthophosphate using the Murphy Riley colorimetric method. Key technical requirements include measuring soil phosphorus within a range of 2.0-100 mg P/kg, having a detection limit of 0.1-5 mg P/L, and featuring a heater system for temperature stabilization.
The specification outlines precise technical and physical constraints, mandating that the new channel must have its own power supply, light source, and detector, with a maximum footprint of 30x30 inches to fit the available lab bench. Additionally, the system must provide full purchase coverage including shipping, installation, training, and a service warranty, and must comply with the "Buy America" statute. The channel is expected to handle deionized water and sodium bicarbonate extracted samples, with appropriate backpressure and debubbler capabilities for reactive samples, and must allow full visibility of fluid movement in the manifolds.

An additional channel to analyze phosphorus is required for a FIALYZER-1000 (FIAlab Instruments, Inc.) flow injection analyzer. The current instrument has three channels for measuring ammonium, nitrate and chloride. Specific requirements are
• Associated equipment necessary for automated phosphorus wet chemistry.
• Compatible with the existing FIALYZER-1000 System that was purchased in 2022 and includes a 240-sample autosampler, computer, software/license, consumables and reagents
• Measure orthophosphate using colorimetry based on the Murphy Riley method (ammonium molybdate/ascorbic acid).
• Handle deionized water and sodium bicarbonate extracted samples, with an appropriate backpressure and debubbler for reactive samples.
• Analytical range for soil phosphorus of at least 2.0 mg P/kg to 100 mg P/kg with a detection limit of at least 0.1 mg P/L up to approximately 5 mg P/L.
• Include a heater system to stabilize temperatures, as the method is temperature sensitive.
• The footprint must be no more than 30 inches deep and 30 inches wide to fit on available lab bench.
• Full view of fluid movement in the manifolds is required.
• Channel must have its own power supply, light source, and detector.
• Provide full purchase coverage, including shipping, installation, training, and a service warranty plan.
• The system must meet “Buy America” statute.
