What is FT-NIR spectroscopy? and what are the advantages with the FT-NIR technology?

Welcome to Q-Interline’s guide on FT-NIR spectroscopy. In this page, we will cover all you need to know about FT-NIR spectroscopy, its applications, and how it can be used to optimize your manufacturing processes.

FT-NIR spectroscopy is a powerful analytical technique providing valuable information about the chemical composition of your samples. Its versatility, speed, and non-destructive nature makes it ideal for use in various industries, including food, dairy, agriculture, and pharma. By using FT-NIR spectroscopy to monitor and control your manufacturing processes, you can improve the quality of your products, reduce waste, and increase profitability.

What is FT-NIR spectroscopy?

FT-NIR spectroscopy stands for Fourier Transform Near-InfraRed spectroscopy. It is a non-destructive analytical technique that uses the near-infrared region of the electromagnetic spectrum to obtain information about a sample’s chemical composition. FT-NIR spectroscopy can be used to identify, quantify, and analyse a wide range of organic and inorganic compounds in various matrices.

How does FT-NIR spectroscopy work?

FT-NIR spectroscopy measures the absorption or transmission of near-infrared light by a sample. The sample is placed in the path of the light beam, and the light interacts with the sample’s molecules. The molecules absorb some of the light at specific wavelengths, which are characteristic of the chemical bonds present in the sample.

FT-NIR spectroscopy uses a Fourier transform to convert the signal from the detector into a spectrum, which contains information about the wavelengths absorbed by the sample. The spectrum is then analysed to identify and quantify the compounds present in the sample.

What are the advantages of FT-NIR spectroscopy?

FT-NIR spectroscopy has several advantages over other analytical techniques:

1. It is non-destructive:
   • FT-NIR spectroscopy does not require sample preparation, and it is a non-destructive technique. This means that the sample can be analysed without altering its chemical composition, and it can be used for quality control of finished products.
2. It is a fast technology
   • FT-NIR spectroscopy is a fast technique providing results in real-time. This makes it ideal for process monitoring and control.
3. It is versatile
   • FT-NIR spectroscopy can be used to analyse a wide range of samples, including solids, liquids, and gases. It can also be used to analyse complex mixtures, such as pharmaceutical formulations and food products. Meaning you can use the same technology and base analyser for endless types of samples.

Who can use FT-NIR spectroscopy?

FT-NIR spectroscopy can be used for analysis of numerous samples in various industries. For the pharmaceutical industry FT-NIR spectroscopy can be used for the analysis of drug formulations, including tablets, capsules, and powders. For chemical industry FT-NIR spectroscopy can be used for the analysis of chemical compounds, including polymers and plastics.

For the dairy industry see some of the advantages of FT-NIR below:

1. Analyse the composition of milk, providing information on the fat, protein, and lactose content. This information can be used to optimize milk production and ensure consistent product quality.
2. Analyse feed, allowing dairy farmers to optimize their feed formulations and improve milk production.
3. Quality control of dairy products, ensuring consistent product quality and reducing waste.

Also, the agricultural industry can gain many advantages of using FT-NIR spectroscopy:

1. Soil analysis, providing information on the nutrient content, pH, and organic matter content. This information can help farmers optimize their fertilizer use and improve crop yields.
2. Analysis of forage, allowing farmers to optimise their feed formulations and ensure the health and productivity of their livestock.
3. Assess the quality of seeds, identifying defects and ensuring optimal germination rates.

Finally, here are some advantages of FT-NIR spectroscopy for the food & ingredients industry:

1. Analysis of food ingredients, including fats, proteins, and carbohydrates. This information can be used to optimize formulations and ensure consistent product quality.
2. Real-time process monitoring of food production, allowing manufacturers to make adjustments to optimize efficiency and quality.
3. Quality control of finished food products, ensuring that products meet regulatory standards and are safe for consumption.
4. Authentication of food products, helping to detect fraudulent or adulterated products.
5. Shelf-life prediction of food products by monitoring chemical changes that occur over time. This information can be used to optimize storage and distribution logistics.

How can FT-NIR spectroscopy help optimize your manufacturing processes?

FT-NIR spectroscopy can help optimize your manufacturing processes by providing real-time information about the chemical composition of your products. This information can be used to monitor and control your manufacturing processes, ensuring that your products are of consistent quality.

FT-NIR spectroscopy can also be used for process monitoring, allowing you to identify and correct issues before they become critical. This can help reduce waste and improve efficiency, leading to cost savings and increased profitability.

The NIR spectrometer is the foundation of all Q-Interline’s analytical solutions.

The NIR spectrometer Quant analyser is based on 2nd-generation FT NIR technology – meaning that high spectral performance is guaranteed while making a low amount of noise. Our NIR instruments vary in scope, size, and central value it brings to the user. We develop, produce and patent a vast variety of accessories to handle analysis of close to all kinds of materials and samples both in laboratory and directly in the process. But the base analyser – the Quant NIR spectrometer – remains the same with the same technology.

Using this NIR spectrometer as the engine, for instance in our highly rated products the DairyQuant Go and InSight Pro, provides the flexible and rigid skeleton of our technological solutions.

NIR spectrometer requires little maintenance

Our NIR spectrometer engine is a technical solution requiring little to no maintenance with high lifetime expectancy element of technology. Both the laser and the light source have an expected lifetime of 10 years, and there is a 3 years warranty on the instrument hardware.

Besides the high-level warranty, the NIR spectrometer is not subject to using any form of chemical components. If you find yourself curious, whether it is about the lack of chemicals in your lab or the unmatched spectral quality overall, do not hesitate to contact us.

Presenting the sample to the NIR spectrometer

We know how important the right knowledge and the right equipment are to applying representative sampling. Ensuring that the results escape contamination and other sampling errors is central – that also means, that the ease of use, which is made possible by the Quant, can decrease risks in error and inaccuracies. The methods to how the samples are presented to the NIR spectrometer developed by Q-Interline are results of years in development combined with decades of experience, driving the power of NIR spectrometer to its full potential.

You can conduct analysis of liquid samples, powdered samples, and solid samples both in laboratory and in process. Sample presentation methods includes use of Petri Sampler, Cup Sampler, Bottle Sampler, Spiral Sampler, and Pivettes®.
