Spectroscopy Spotlight: What It Is and Why It Matters in SA Labs

Imagine being able to identify the composition of a substance without altering or destroying it.

This is the remarkable capability of spectroscopy – a technique that allows scientists to “see” the invisible by analysing how light interacts with matter. In South African laboratories, spectroscopy plays a crucial role in ensuring the safety of our water, the efficacy of our medications, and the quality of our food.

The challenge of accurate, non-destructive analysis

In laboratories across South Africa, identifying and quantifying complex substances is a key challenge. Traditional methods often require time-consuming preparation and can be destructive. FTIR spectroscopy offers a non-destructive solution, making it ideal for lithium-ion battery (LIB) research. The Agilent Cary 630 FTIR spectrometer helps scientists analyse critical battery components, such as electrodes, electrolytes, and polymers, with speed and precision. This allows for better optimisation of materials, leading to more efficient, durable, and cost-effective batteries; paving the way for safer and high-performance energy storage solutions.

There is a growing need for techniques that are both precise and non-invasive, allowing for rapid analysis without compromising the integrity of the sample.

Beyond the Brew: Insights into Beer Testing

Beer is more than just a refreshing beverage – it’s a carefully crafted balance of ingredients, chemistry, and precision. From the selection of raw materials to the final pour, ensuring the highest quality requires rigorous testing at every stage. Modern analytical instruments have revolutionised beer analysis, giving brewers deeper insights into composition, consistency, and safety. At Chemetrix, we support brewers with cutting-edge solutions to maintain excellence in every batch.

 

The importance of beer analysis

For centuries, brewing has been both an art and a science. Today, breweries of all sizes rely on analytical testing to:

  • Ensure product consistency and quality control
  • Detect contaminants or unwanted elements
  • Monitor fermentation efficiency
  • Comply with safety and regulatory standards

Without accurate analysis, a beer’s taste, aroma, and mouthfeel could be compromised, potentially impacting consumer trust and brand reputation.

Key techniques in beer testing

Several advanced techniques are used to analyse beer, from raw materials to the finished product. The latest innovations in spectroscopy and chromatography allow for precise monitoring of chemical composition, ensuring every pint meets the highest standards.

Elemental analysis with ICP-OES

Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is an essential tool in beer analysis, particularly for detecting and quantifying metallic elements. Metals such as iron, copper, and zinc can influence beer’s taste, stability, and shelf life. Excessive levels can lead to oxidation and undesirable flavours. The Agilent 5900 ICP-OES is a preferred instrument in the brewing industry, offering fast, multi-element analysis with exceptional sensitivity. By monitoring metal content, brewers can ensure consistency and prevent unwanted chemical reactions.

Monitoring yeast growth with UV-Vis spectroscopy

Yeast plays a crucial role in fermentation, converting sugars into alcohol and carbon dioxide. Monitoring yeast health and growth rate is vital for efficient fermentation. UV-Vis spectroscopy, such as the Agilent Cary 60 UV-Vis, provides rapid and accurate yeast cell density measurements. This allows brewers to optimise fermentation conditions, reducing inconsistencies and improving beer quality.

Atomic Absorption Spectrometry (AAS) for trace metal detection

Even trace amounts of heavy metals can impact beer’s stability and flavour profile. Atomic Absorption Spectrometry (AAS) is used to detect elements like lead, arsenic, and cadmium at very low concentrations. The Agilent 240FS AA offers high-speed analysis with precision, ensuring contaminants remain below regulatory limits.
