For fast and accurate FTIR, FT-NIR, and FT-MIR analysis in a flexible, highly configurable system, count on our market-leading infrared spectrometers and instrumentation. Some common applications for molecular spectroscopy study in the near, near-mid, mid-far and far infrared regions include:

  • Chemicals and Materials: Troubleshoot manufacturing problems; identify product contaminants; analyze fuels; gain deeper insights into the properties of novel and advanced materials.
  • Pharmaceuticals: Analyze product formulations and package coatings; rapidly screen the quality of raw materials, intermediates and formulated products; qualify nutraceuticals.
  • Food: Screen for known and unknown adulterants.
  • Environmental Safety: Accurately determine and monitor hydrocarbon levels in the environment.

We also offer all the consumables you’ll need, including sampling cells and windows, desiccant kits, and introductory kits that give newer IR researchers valuable experience with IR spectrometers and sampling.

    Safeguarding the Authenticity of Herbs & Spices

    Infrared (IR) and near-infrared (NIR) spectroscopy are fast, easy-to-use techniques with a history of being used for food applications such as those for measuring protein, moisture, and fat content. Food fraud and adulteration has become of particular concern to the industry over the past few years following reports of incidents in the media, with herbs and spices identified as one of the key problem areas.

  • Application Note

    Determination of Benzene in Gasoline by ASTM D6277 with Spectrum Two

    IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.

  • Application Note

    Cavity-enhanced Absorption Spectroscopy for Trace Gas Detection with Frontier

    Cavity-enhanced absorption spectroscopy (CEAS) has similarities with the better known cavity ringdown technique (CRDS) which measures the signal decay as a laser pulse emerges through one of the mirrors after successive reflections. By measuring the increase in the rate of decay caused by an absorbing species, CRDS can measure ppb concentrations of small molecules. The ringdown technique has typically been applied to small molecules where the wavelength of a NIR laser source can be tuned across very narrow individual lines of the spectra. In contrast this report describes CEAS using a broadband source applied to larger molecules where the spectra are broader.

  • Application Note

    Determination of Oil Content in Membranes Used in Compressed Air Sampling by Infrared Spectroscopy

    This note describes the test method for the quantitative analysis of aerosol oil and liquid oil typically present in the air discharged from compressors and compressed air systems. The method is rapid, sensitive and cost effective and shows the FT-IR can be an effective tool for the monitoring of oil content. The methodology followed for the analysis by FT-IR is reported in Bureau of Indian Standard and we have also tested for its ruggedness, spike recovery, linearity and detection limits.

    Discrimination of Herbal Lifestyle Products Using AssureID SIMCA and COMPARE Algorithms

    Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by scientific papers, and on some occasions the media, as being inferior to orthodox treatment. This is due to the variation between herbal formulations which will not be present in so called ‘single-chemical’ drugs. The reasons for the aforementioned variation involve several factors including storage, environmental conditions, handling and unintentional or intentional contamination (adulteration).

    Diamond ATR and Calibration Transfer for Biodiesel-Blend Analysis by ASTM D7371

    Biodiesel is seldom used neat (B100), typically being blended with fossil diesel at ratios from 5% v/v (B5) to 30% v/v (B30). Verifying the FAME content of diesel-fuel blends is an important aspect of quality control and auditing of blending and distribution operations. Because FAME has a strong infrared absorption at 1745 cm-1 due to the ester carbonyl group, infrared spectroscopy is an excellent technique for this analysis, and there are EN and ASTM® standard test methods describing the procedure

  • Application Note

    A novel method (TG-IR) for the rapid determination of Total Petroleum Hydrocarbons (TPH) in soil

    A gas chromatographic analysis of the extract can provide even greater sensitivity and more detailed compositional information, but further increases the time required for the analysis. Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) can provide detailed information about the amount and nature of the pollution, while requiring no sample preparation at all. This application note illustrates the kind of data that can be obtained with a modern TG-IR system.

  • Application Note

    Augmenting Standard Methods of Measuring Airborne PM2.5 Using IR Imaging

    The use of IR imaging expands the measurement possibilities by giving information about the individual types of materials present in the collected particles. The information from the IR imaging experiment is not only qualitative (i.e. identification of the particulates), but can also be calibrated to give quantitative information on the components present. The IR imaging measurement will take only five minutes, whereas Ion Chromatography requires solvent extraction of the particulates and would take around 20-25 minutes per sample

  • Application Note

    Biodiesel Concentration Measurements Using Attenuated Total Reflectance (ATR)

    Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.

  • Application Note

    Quality Control of Olives by Near-Infrared Spectroscopy and AssureID Software

    Olive oil is an increasingly popular food product worldwide, with global production exceeding 3.0 million tons in 2011 and showing steady annual growth. Despite these huge volumes, however, margins are relatively small in olive oil production so quick and easy analysis of oil quality is vital to maintain process efficiency. Rapid, reliable analysis can contribute to process and quality improvements in numerous ways.
