Breakthrough curve measurement allows high-throughput screening and testing of adsorbents. Adsorptive separation processes have wide ranging practical applications including CO2 capture and storage, purification and recovery of noble gases, natural gas and biogas upgrading, toxic gas removal and air separation.
Hiden Isochema’s ABR is designed to meet the needs of researchers wishing to characterise the gas separation performance of novel materials such as metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs) and covalent organic frameworks (COFs) without the time or expense of synthesising larger quantities of material. We featured highlights of some recent installations in previous blog posts and elsewhere.
The ABR is a dedicated breakthrough analyzer (BTA), fully automated and supplied with an integrated close-coupled mass spectrometer. The ABR is available on a range of configurations optimised to suit research-scale samples, with bed volumes from 2 cc to 20 cc. Up to 6 gas inlets are available as well as a dedicated purge stream. Flow rates are selected to suit the specific applications, and the ABR includes an ultra-low dead volume switching valve.
Options include an upgrade for operation at pressures to 50 bar, and an integrated vapor generator module for gas-vapor operation. The breakthrough data obtained is complementary to the adsorption-desorption isotherms measured with our IGA, XEMIS and IMI sorption analyzers.
ABR Key Features:
- Fully automated breakthrough analyser
- Optimised for research-scale sample sizes (bed sizes from 2 cc)
- Ultralow dead volume automated switching (purge gas/process mixture)
- Options for gas-gas, gas-vapor, vapor-vapor configurations
- Optional high pressure (50 bar) configuration
- Fully integrated close-coupled mass spectrometer
Leaks in the System
- Any leak will cause a pressure change that is not due to sorption.
- A pressure drop due to an outboard leak will appear as adsorption and a pressure increase due to an inboard leak will appear as desorption.
- Routine vacuum hold and pressure hold tests should be conducted to ensure the system is leak tight.
