New Article: Mass Spectrometry in Real Time

Mass spectrometry as a technique has grown significantly in recent decades, with many analytical requirements are addressed by mass spectrometry in some form or other.

The techniques of ionisation, mass separation and detection are varied, and the process is now used in analytical sectors ranging from relatively simple vacuum and vacuum process monitoring to the more complex life sciences and biomedical applications.

Peter Hatton and Dr David Lundie of Hiden Analytical have written an article “Mass Spectrometry in Real Time” recently published in the July edition of Labmate UK & Ireland. In this article they address the little known but powerful technique of real time mass spectrometry by quadrupole mass spectrometry applied to gas analysis and dissolved gas analysis in environmental studies, catalysis, electrochemistry and thermo-gravimetric mass spectrometry, TG-MS. The article describes how the technology works, and how it is applied to several key applications at near atmospheric pressure with both portable and laboratory devices.

Surface Engineering & Thin Film Nanotechnology

Nanotechnology represents a new frontier in research and development (R&D) across a broad spectrum of human endeavours. Though concerned with the miniscule, the scope of nanotechnology is undeniably vast. However, most of the exciting nanoscience research being conducted is in a purely contemplative phase – or at least an extended period of prototypical development.

The Reality of Modern Nanotechnology

Consider graphene: A monomolecular allotrope of carbon that was first isolated from graphite via physical exfoliation over a decade ago. Though remarkable as the first atomically thick substance ever engineered, media hyperbole regarding next-generation applications of graphene have largely proven fruitless. That isn’t to say that graphene hasn’t been successfully functionalised, just that the realm of nanotechnology has a fair way to go before the likes of magnetic medicine and quantum computing become our new reality.

Exploring Spectrometers for Thin Film Applications

One of the few functional successes of nanoscience to date is the thin film. Though there is no singular definition of thickness that constitutes a thin film, they typically deal with coatings that are no thicker than a few micrometres (μm). Manufacturers are increasingly able to deposit precise thin coatings of just a few nanometres (nm) due to improvements in process sophistication and quality. This advanced method of surface engineering has proven essential to the ongoing ingenuity of manufacturers and researchers in a range of fields.

Cutting-Edge Surface Engineering

Select coating processes, such as atomic layer deposition (ALD), have pushed the boundaries of thin film nanotechnology by enabling the production of conformal films with tight control of both composition and thickness at the atomic range. By selectively and sequentially introducing precursor gases into an ALD vacuum chamber, complex substrates are exposed to individual gas phases in a series of alternating cycles. Gas molecules precipitate on the target surface in a self-limiting manner, which means reactions cease as soon as all reaction sites are occupied. Theoretically, this yields a precisely uniform, extremely thin coating of precipitate which acts as the new reaction surface for subsequent gas phase molecules.

ALD is envisaged as one of the greatest processes for electronic device miniaturization, next-level integrated circuit (IC) density, and novel energy storage systems. However, it is not a singular process and is instead used as an umbrella term to encompass a broad framework of systems that operate on these basic surface engineering principles.

Thin Films & Nanomaterials Today

Yet, even as mankind’s chemical surface engineering efforts continue to push towards the atomic scale, research at the nano-, micro- and even macroscales are continuing to pay dividends in terms of nanotechnological progress.

Vacuum-rated crystal growth furnaces are increasingly used to develop high-purity semiconducting alloys such as gallium arsenide or indium phosphide, both critical contenders for high bandgap multijunction photovoltaics – also known as tandem solar cells. These are generated epitaxially, much like conventional silicon, but offer dramatically improved quantum efficiency and performance.

We are also beginning to see the increased application of nanocrystals in the form of quantum dots (QDs); electro- and photoluminescent materials that are mainly used in display applications due to their outstanding spectral characteristics. Materials like QDs are expected to form part of the backbone of the display and lighting market in the coming years, even as scientists continue to explore novel uses of synthesised nanocrystals such as energy generation and nanomedicine.

Carefully engineered micro-electromechanical systems (MEMS) based on thin films on the order of micrometres are similarly pushing the technological letter in the field of telecommunications, as ultrafast 5G networks continue to rollout across the world.

Solar Cell Thin Film Analysers: The Basics

Global energy consumption is rapidly outstripping the available supply. When we factor in that over half of the world’s electricity is generated by non-renewables and that the global population growth remains incredibly high, concerns about the energy sector’s ability to provide for future generations seem well-founded. A gradual pivot towards renewables seems both inevitable and logical, but there are bottlenecks to such a transition.

Solar Cell Thin Film Analysers from Hiden Analytical

Solar cells, for instance, are among the front-running technologies in renewable energy, but current generation photovoltaics are simply incapable of providing the quantities of energy that we need to reduce our reliance on fossil fuels. This is primarily due to inefficiencies in quantum efficiency and high production costs. Thin-film solar cells could dramatically improve this dynamic, but – as the technology remains in the research and development (R&D) phase of its lifecycle – large-scale market penetration will rely on robust solar cell thin film analyzers.

What is a Solar Cell Thin Film Analyser?

A solar cell thin film analyzer technically refers to any analytical system used to investigate photovoltaic cells that are comprised of multiple layers of material with micro- and sub-micro scale (μm) thicknesses.

At Hiden Analytical, we have spent decades building a proprietary catalog of quadrupole mass spectrometers for an array of high-technology applications, building a reputation as the go-to provider of thin film analyzers irrespective of the underlying processing method. This has enabled us to support innovative research into novel photovoltaic structures with specialist solar cell thin film analyzers like the SIMS Workstation.

Secondary ion mass spectrometry (SIMS) is an extremely sensitive and versatile technique used for depth profiling of various substrate types. Using a cesium or oxygen ion gun to sputter surfaces and an integrated detector to obtain and profile secondary ions ejected from a sample’s uppermost surface levels, SIMS analysis enables researchers to characterize samples under test with a mass range of up to 5000 atomic mass units (AMU) at depths of 30μm down to a single atomic layer.

The SIMS method works so well for solar cell thin film analyzers due to this outstanding combination of sensitivity and depth resolution. Unlike conventional solar cells, which are composed of thick films of alternating p- and n-type crystalline silicon (c-Si), emerging photovoltaics based on thin films comprise several different semiconductors stacked on top of one another. This is what is known as a multi-junction, or tandem, photovoltaic cell.

The Importance of Tandem Solar Cells

Tandem solar panels do already exist, but thin film photovoltaic cells are still a relatively immature technology, with extensive R&D still ongoing into the best possible materials and structures. Solar cell thin film analyzers are an essential driving force behind this intensive research, spearheading greater quantum efficiencies in solar power. This could prove integral to providing clean energy to future generations.

The Working Principle of a Mass Spectrometer

Updated: Originally published 14/02/2018

The analytical technique of mass spectrometry has a broad range of uses including to identify unknown compounds within a material, measure the amount of a known material that is present in a sample, and to measure changes in sample composition in real time. Mass spectrometry is applied to solids , liquids, gases and vapour.

Mass Spectrometer Components

Every mass spectrometer consists of three basic components; the ion source, the analyzer, and the detector system.

The ion source is used to generate the gaseous ions from the sample, which are required to perform the measurement. The analyzer is used to separate the different types of ions according to their mass-to-charge ratio, and the detector reads these ions and records the amount in each group.

Mass Spectrometer Process

The first part of the process within a mass spectrometer is ionization, and this occurs when an atom within the sample gains a negative or positive charge. Most standard mass spectrometers work with positive ions.

Once the ions are generated, they are all accelerated to ensure they all have the same kinetic energy, and they are then deflected by a field according to their mass-to-charge ratio to filter the ions into a detector.
