Pharmaceutical applications of terahertz spectroscopy and imaging

Daniel Markl ; Michael T. Ruggiero and J. Axel Zeitler

Terahertz spectroscopy and imaging techniques have advanced the chemical and physical characterisation of active pharmaceutical ingredients (APIs), excipients and final solid dosage forms. Terahertz radiation can be used to investigate both chemical and solid structures, as well as provide information on the bulk morphology of pharmaceutical materials. The penetrating and non-destructive properties of terahertz light, coupled with its high acquisition rate, makes this technology a promising candidate for process analytical technology (PAT) applications.

Terahertz radiation corresponds to frequencies between the microwave and infrared regions of the electromagnetic spectrum (300 GHz to 10 THz, or wavelengths of 1mm to 1μm). For many years the terahertz region had been referred to as the ‘terahertz gap’ because of the difficulties in generating and detecting terahertz light. This has changed over the past few decades due to major advances that have brought down costs and instrument size, from $500,000+ laser systems that can take up an entire laboratory space to sub-$100,000 benchtop – and even hand-held – devices. Such breakthroughs have brought terahertz techniques into the mainstream and have enabled terahertz technologies to be implemented in industrial settings.

New Imaging Spectroscopy Facility at UWA

Professor Vincent Wallace

The University of Western Australia’s Physics Department boasts a new imaging and spectroscopy facility that has the potential to transform crude oil production and refinery processes.

Cutting edge technology is a priority for oil and gas companies who face an increasingly competitive market and are looking for an edge that makes them stand out against the rest.

At UWA our scientists are working with new technologies that will revolutionise the industry and add value to a company’s bottom line through improved productivity.

One such technology is a state-of-the-art terahertz (THz) imaging and spectroscopy system, the TeraPulse 4000, that has just been installed in the School of Physics and is the first of its kind in WA.

UWA’s Associate Professor Vincent Wallace is the co-inventor on several patents relating to THz technologies and he expands on why this technology is a novel tool for industry:

“For the oil and gas, and resources industry, THz spectroscopy provides the capability to understand numerous problems like water content and crude oil viscosity.”

"THz spectroscopy is ideally suited for probing intermolecular interactions and low-energy vibrational, rotational and librational modes of various components of crude oil and the aggregation of certain compounds like asphaltenes."

“Asphaltenes are heavy, polar aromatic molecules found in crude oils that due to aggregation increases its viscosity and thus make it more difficult to extract. Typically, solvents like toluene or benzene are used to dissolve these compounds but there is a lack of understanding as to why they form in the first place.”

 “It is this type of problem that I am looking to engage with industry and solve, using this cutting edge technology. By understanding why asphatelenes form, it will provide us the key to removing them prior to or during extraction and potentially transforming production quality.”

TeraView at SEMICON Taiwan

TeraView will be exhibiting at this year's SEMICON Taiwan. The event will take place between September 7-9 in Taipei, Taiwan.

We will be showcasing our latest product, the EOTPR 5000.

"TeraView’s proprietary Electro Optical Terahertz Pulse Reflectometry (EOTPR) technology provides a 5 micron resolution capability in isolating faults within advanced integrated circuits for mobile phones and computing, including complex packages such as Package on Package (PoP), flip chip, and 3D package with Through Silicon Vias (TSVs). EOTPR has been widely accepted by advanced IC package failure analysis community, and this technology is ready to be deployed in the high volume manufacturing environment for quality assurance inspection."

EOTPR 5000 launches at SEMICON West, USA.

This year's SEMICON West event in San Francisco saw the launch of our fully automated integrated circuit (IC) package inspection system, the EOTPR 5000.

Building on the success of the EOTPR 2000 which has an established track record in the industry for rapid fault isolation and manual inspection, the EOTPR 5000 is a fully automated advanced IC package inspection system that utilizes TeraView’s proprietary EOTPR terahertz technology to detect weak or marginal interconnect quality in high volume manufacturing environments, which no other technology can detect today.

Don Arnone, TeraView CEO, spoke to Philip Stoten of EMSNowTV (above) to discuss what drove the technology and how it is currently being deployed.
