The CATLAB integrated micro-reactor/mass spectrometer system is specifically optimised for continuous quantitative real-time analysis of catalytic activity and reaction components. The close-coupled mass spectrometer samples directly from the reactor zone for fastest response and precise process characterisation, providing overall response times of less than 0.5 seconds and with data accumulation rates at up to 500 data-points per second.
The latest brochure, just released, details new features to extend operational capability and ease of operation, with total system control now offered via the new LabView operating program with both fully automated and with manual operation. Operation is fully pre-programmable with total control of temperature, temperature ramp rate and of gas flow with up to 8 gas streams.
The quartz reactor and cartridge-style sample insertion system are now available with increased capacity for operation with sample volumes from 0.15 up to 2.5 mL, with the fast-response low thermal mass furnace operating to 1000C with ramp rates to 20C per minute. Applications include temperature programmed desorption(TPD), reduction(TPR), oxidation(TPO) and reaction(TPRx). Additionally the mass spectrometer module may be decoupled to provide standalone operation for general laboratory gas analysis applications.

AFM-IR enables chemical metrology for nano-manufacturing | Laboratory Talk

One of the key achievements of the nanotechnology era is the development of manufacturing technologies that can fabricate nanostructures formed from multiple materials.

Such nanometer-scale integration of composite materials has enabled innovations in electronic devices, solar cells, and medical diagnostics.

While there have been significant breakthroughs in nano-manufacturing, there has been much less progress on the metrology of nanostructures made from multiple integrated materials. Researchers at the University of Illinois Urbana-Champaign and Anasys Instruments Inc. now report new diagnostic tools that can support cutting-edge nano-manufacturing.

“We have used atomic force microscope-based infrared spectroscopy (AFM-IR) to characterize polymer nanostructures and systems of integrated polymer nanostructures,” said William King, the College of Engineering Bliss Professor in the Department of Mechanical Science and Engineering at the University of Illinois Urbana-Champaign.

“In this research, we have been able to chemically analyse polymer lines as small as 100 nm. We can also clearly distinguish different nanopatterned polymers using their infrared absorption spectra as obtained by the AFM-IR technique.”

“While nanotechnologists have long been interested in the manufacturing of integrated nanostructures, they have been limited by the lack of tools that can identify material composition at the nanometer scale,” said Craig Prater, co-author on the study and Chief Technology Officer of Anasys Instruments Inc.

“The AFM-IR technique offers the unique capability to simultaneously map the morphology and perform chemical analysis at the nanoscale.”
