Multiport Surface Characterization Analyzer

Binghamton University intends to procure a fully automated gas sorption analyzer designed for high-resolution characterization of specific surface area and pore size distributions. The system must meet or exceed the following minimum specifications:

1. Instrument Configuration

• The analyzer must support multiport operation, including:

o One port configured for micropore analysis

o Two ports configured for mesopore analysis

• All ports must operate independently or simultaneously to enable high-throughput analysis.

1. Measurement Capabilities

• Must provide high-resolution physisorption analysis to determine:

o Specific surface area

o Pore volume

o Pore size distributions

• Capable of resolving pores in the range of 0.35 to 500 nm
• Minimum measurable surface area must be:

o 0.01 m2/g, and as low as 0.0005 m2/g using low-pressure adsorptives (e.g., krypton)

1. Gas Compatibility

• Compatible with non-corrosive gases, including but not limited to:

o Nitrogen (N ), Oxygen (0 ), Argon (Ar), Krypton (Kr), Carbon Dioxide (CO ), Carbon Monoxide (CO), Hydrogen (H ), and Butane

1. Vacuum Performance

• The vacuum system must include:

o A turbo molecular drag pump in series with a four-stage diaphragm pump

• Achieve an ultimate vacuum of 3. 75 x 1 o-i mm Hg
• Manifold outgas rate must be less than 0.1 1,.1m/min

1. Pressure Transducer Accuracy

• System must be equipped with transducers meeting or exceeding:

o ±0.12% of reading at 1000 mmHg and 10 mmHg (resolution?? 0.0001 mmHg)

o ±0.15% of reading at 0.1 mmHg (resolution ?? 0.000001 mmHg)

1. Thermal and Cryogen Control

• Must include passive isothermal cryogen jacket or equivalent mechanism to maintain cryogenic conditions at the sample tube

1. System Materials and Valving

• Construction must feature:

o Stainless steel gas lines, VCR connections, and a leak-tight manifold

o Pneumatically actuated, hard-seal valves to ensure clean, contamination-free operation

1. Software and Diagnostics

• Must include a comprehensive software suite providing:

o Instrument control and real-time data acquisition

o Customizable reporting and advanced data analysis

o Diagnostic dashboard for monitoring system performance and maintenance status

1. Accessories

• The analyzer must be compatible with an external degassing unit capable of preparing samples under vacuum or inert gas flow at elevated temperatures prior to analysis
• The analyzer must be compatible with a Peltier Temperature Control Device capable of maintaining a constant temperature between 0°C and 80°C
