Subject: Purchase of Measurement Instrument for Concentrated System Particle Size Distribution and Zeta Potential 2. Purpose: To purchase a measurement instrument for concentrated system particle size distribution and zeta potential, which is necessary for analyzing and evaluating surface properties such as aggregation and dispersion states through particle size distribution and surface potential (zeta potential) measurements, in order to evaluate the generation behavior and irradiation effects of radiation decomposition products in systems where solids such as insoluble fine particles like carbonate slurries and powdered debris are mixed with aqueous solutions, in research and development related to comprehensive analysis technology for radiation decomposition behavior. 3. Specifications of Purchased Item: One set of Mass Applied Science "Zeta-APS200di" concentrated system particle size distribution and zeta potential measurement instrument combined with an automatic titration unit option, capable of simultaneously measuring particle size distribution and zeta potential while controlling the pH of concentrated suspensions with high suspended solids in an aqueous medium, or equivalent products that meet the following requirements. However, considering the recent soaring prices and long delivery times for electrical and electronic equipment, used products manufactured within the last year (with minimal damage or degradation, and usable without problems) are also acceptable. * Concentrated system particle size distribution and zeta potential measurement instrument (with automatic titration unit) - The particle size distribution measurement method shall be the ultrasonic attenuation method, and the zeta potential measurement method shall be the electroacoustic amplification (ESA) method. Simultaneous measurement of particle size distribution and zeta potential shall be possible. - The probe for particle size distribution measurement shall consist of an ultrasonic transmitter, receiver, and a movable reflector, and the drive unit and drive rod of the reflector shall be configured and structured so as not to come into contact with the sample liquid. It shall be structured so that measurement is possible by immersing only the ultrasonic transmitter/receiver and reflector at the probe tip into the sample. Furthermore, measurement independent of fixed sample containers such as disposable containers shall be possible. - Shall be equipped with a pH meter, an electrical conductivity meter, a temperature measurement probe, and an ESA method zeta potential measurement sensor (non-resonant type). - Shall be equipped with an automatic titration unit capable of using two types of liquids with a resolution of 1 μL or more. - Shall have a structure that allows optional use of a magnetic stirrer, agitator, etc., for sample stirring when the measurement probe, etc., is in place. - Shall include a personal computer for instrument control and analysis with analysis software installed. - The minimum sample volume required for particle size distribution measurement shall be 100 mL or less. For zeta potential measurement only, the minimum required volume shall be 30 mL or less. In addition, the minimum required volume for simultaneous measurement of particle size distribution, zeta potential, pH, and electrical conductivity shall be 200 mL or less. - The range of solid content in the sample for which particle size distribution and zeta potential can be measured shall include 0.1 to 60 vol%. - The range of viscosity of the sample for which particle size distribution and zeta potential can be measured shall include up to 20000 cp. - The range of particle size for which particle size distribution can be measured shall include 5 nm to 100 μm. The range of particle size for which zeta potential can be measured shall include 0.1 nm to 30 μm. 3/4 - There shall be no limitation due to electrical conductivity in particle size distribution measurement. The range of electrical conductivity for which zeta potential can be measured shall include 0 to 5 S/m. - Particle size distribution and zeta potential measurement shall be possible for samples with a pH range of 0 to 14. - The range of measurement acoustic (ultrasonic) frequency for particle size distribution measurement shall include 1 to 100 MHz. - The measurable range of sound velocity shall include 800 to 2000 m/sec. - The measurable range of zeta potential shall include -500 to +500 mV. - The measurable range of temperature shall include 10 to 50°C. - The measurable range of electrical conductivity shall include 0 to 5 S/m. - Automatic measurement of the isoelectric point in conjunction with the automatic titration unit shall be possible. Automatic measurement of the effects of pH or reagent concentration changes shall also be possible. - Particle shape assumption shall not be required for particle size distribution analysis. Calculation of differential and cumulative particle size distributions based on volume, area, and number shall be possible. 4. Delivery Deadline: February 26, Reiwa 9 (2027) 5. Delivery Location and Conditions (1) Delivery Location: Room 347, Building No. 2, Advanced Science Research Center, National Research and Development Agency Japan Atomic Energy Agency, 2-4 Shirakata, Tokai-mura, Naka-gun, Ibaraki Prefecture (2) Delivery Conditions: Delivered after installation (installation of the main unit and accessories on the experimental bench after delivery and unpacking, connection of each part, and preparation for startup). 6. Acceptance Conditions: Acceptance will be made upon successful completion of quantity inspection, appearance inspection, and operational verification inspection after delivery to the location specified in Item 5 (1). Operational verification inspection shall include instrument calibration, measurement of standard samples defined by the manufacturer, and confirmation that the inspection items meet the criteria, and that the instrument can be started up, and that zeta potential and particle size distribution can be measured and the process completed without issues. 7. Documents to be Submitted: For used items, documents indicating the manufacturing date must be submitted. 4/4 8. Promotion of Green Purchasing: In this contract, environmentally friendly products (office supplies, OA equipment, etc.) applicable to the Green Purchasing Act (Act on Promoting Procurement of Environmentally Friendly Goods and Services by the Government and Other Entities) shall be adopted whenever possible. 9. Consultation: In case of any doubt regarding matters described in these specifications or matters not described herein, consult with the Japan Atomic Energy Agency and follow their decisions. 10. Other: The contractor shall act in accordance with the instructions of the Japan Atomic Energy Agency in the event of an abnormal situation occurring during the installation of purchased items in the facilities of the Japan Atomic Energy Agency. Furthermore, if an abnormal situation occurs due to work performed under the contract, the contractor shall analyze the cause and consider countermeasures, make improvements proactively, and obtain confirmation from the Japan Atomic Energy Agency regarding the results of the cause analysis and countermeasures.
