Statement of Requirements:
The requested Microgravimetric gas/vapour adsorption analyzer is a critical piece of infrastructure required to evaluate the performance of porous materials for thermal energy storage and gas separation applications. This emcompasses processes such as thermal energy storage by moisture adsorption from air, pre-combustion/post-combustion CO2 capture, as well as biogas, and other gas separations, which are at the forefront of new technologies for clean enrgy generation and storage. This piece of equipement is complementary to existing gas adsorption equipment.
General Description:
The selective gas/vapour adsorption analyzer will be capable of measuring the adsorption behaviour of porous solids, including metal-organic frameworks, covalent organic frameworks and zeolites for pure gas adsorption, as well as moisture adsorption from air. Importantly, this will allow for adsorption capacity measurements allowing for the determination of adsorption rate, selectivity, uptake capacity and adsorption equilibrium. This system should be compatible with a range of industrially relevant gases including CO2, H2, N2, CH4, higher hydrocarbons, CO, O2, to name a few, and be suitable for water/VOC/alcohol vapour adsorption capabitilies in air.
Furthermore, the instument should allow for automated adsorption measurements at constant moisture conditions, and thus, the controlled mixing of water vapour in air/ N2 gas to achieve desired constant relative humidities is essential. Instrument should also allow for the preparation and activation of samples at high temperatures, at least up to 400oC, as well as very high vacuum (almost zero absolute pressure, such as 10-6 torr) and would allow gas adsorption isotherms in the range of -50 to 100oC, and vapour adsorption in the range of 5 to 80oC. This should be suitable for microporous and mesoporous materials, both in the powder form, as well as in pellet form.
Minimum Mandatory Requirements:
1.Microgravimetric Gas/Vapor Adsorption Analyzer System
1.1Must allow for activation of samples, including in-situ preparation at temperatures up to a minimum of 400 oC and at very low pressure with a maximum of 10-6 Torr pressure.
1.2Must be suitable for microporous and mesoporous samples, including materials based on metal-organic frameworks, covalent organic frameworks and zeolites, both in powder and pellet form.
1.3Must be able to automatically hold constant relative humidity in the air/N2 gas to be able to measure moisture/vapour adsorption capacities.
1.4Must allow for evaluating the adsorption behaviour of gases including CO2, H2, N2, O2, CO, CH4, and other hydrocarbons up to C3.
1.5Must allow for evaluating the adsorption behaviour of vapours, including alcohols, water, and higher hydrocarbons up to C8.
1.6Must allow gas adsorption isotherms in the range of -50 to 100oC, and vapour adsorption in the range of 5 to 80oC.
1.7Must include a software for generating reports of the analysis.
1.8Must include a computer to perform the analyses and generate the required reports.
2.Other requirements

2.2Must include 2 years manufacturer’s warranty.
2.3Must include installation and on-site training.
