About this file
This notice announces the Department of Agriculture Agricultural Research Service's intent to award a sole source contract for an oxidation stability analysis machine. The machine will be used to determine the oil stability index of foods and oils according to AOCS method Cd 12b-92. The incumbent contractor is Metrohm USA, Inc. of Riverview, Florida. Responses to identify capability to fulfill the requirement are due by March 22, 2024 and shall be emailed to Joel Maas. A determination on sole sourcing will be at the Government's discretion. The analysis machine must accommodate a minimum of eight samples from 50-220 degrees Celsius in one degree increments. Software is required to monitor conductivity and calculate endpoints automatically or manually from probes. Delivery within 120 days of order is required.

Project Oxidation Stability Analysis Machine
General Information
1.0 Scope of Work
Purchase an oxidation stability analysis machine for the purpose of determining the “Oil Stability Index” of food fats and oils for ARS research according to AOCS official method Cd 12b-92. Since the instrument may occasionally also be used for biodiesel analysis by the BOR research unit, the biodiesel method sample programming was also requested as an add-on.
2.0 Background
An instrument is required for the purpose of determining the Oil Stability Index of fats and oils according to the AOCS official method Cd 12b-92. The requirements and specifications of the instrument are laid out by the method and are copied below.
3.0 Technical Requirements / Tasks
• instrument that can measure the oxidative stability index of fats and oils and biodiesel according to AOCS official method Cd 1b-92, ISO 6886.
• A minimum of eight sample measuring locations
• Temperature range of 50°C to 220°C that can be set in steps of 1°C increments.
• Temperature calibration/correction capability, and maximum deviation of < 0.3°C from the set temperature.
• Built-in air pump with a flow range of 1-25 L/h
• Conductivity measuring vessels with a conductivity measuring capability of 0-400 µs/cm.
• Conductivity measurement vessels capable of holding 50 ml of water, and capable of covering the tip of an aeration tube by 5 cm or more.
• Must interface with a computer through a USB or similar port interface.
• Software that when operated through a computer, should monitor the conductivity of each probe and be able to automatically calculate the end point, or be configured to manually calculate the endpoint, and save data.
