Frequently asked questions

What is optical analysis?

Optical analysis studies how light interacts with matter to identify and quantify chemical compositions. It involves examining the behavior of electromagnetic radiation—particularly in the ultraviolet, visible, and infrared regions of the spectrum—as it is absorbed, emitted, scattered, or transmitted by materials. This type of optical analysis is fundamental in fields such as spectroscopy, imaging, and microscopy, where understanding the properties of light and its interaction with matter reveals critical information about molecular structure, composition, and dynamics. To fully grasp how optical analysis works, it is important to understand the nature of electromagnetic radiation and how it interacts with matter.

What is electromagnetic radiation?

The electromagnetic spectrum represents the full range of all frequencies or wavelengths of electromagnetic radiation. Electromagnetic radiation is classified by wavelength into radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. The behavior of electromagnetic radiation depends on its wavelength. Electromagnetic radiation has both wave and particle properties. A charge at rest produces an electric field and a moving charge generates both electric and magnetic fields. Accelerated charges emit electromagnetic radiation.

How does electromagnetic radiation interact with matter?

The interaction of electromagnetic radiation with matter can involve absorption, emission, or scattering of radiation. The magnitude of interaction between electromagnetic radiation and matter depends on the size of the molecular dipole moment. Different regions of the light spectrum are used to understand various molecular or atomic properties.

What is spectroscopy?

Spectroscopy is the study of the interaction of electromagnetic radiation with matter involving absorption, emission, or scattering of radiation. It has been an essential tool for understanding atomic or molecular composition and structure.

What are spectroscopy techniques and/or measuring methods for chemical analysis?

Since 2012, Endress+Hauser has invested in technologies for inline or laboratory optical analysis, gas monitoring, and laboratory automation, including the acquisitions of SpectraSensors, Kaiser Optical Systems, Analytik Jena, and Blue Ocean Nova AG, as well as a strategic partnership with SICK AG. Within this expanded analysis portfolio, we offer a full range of spectroscopy tools. We use spectroscopy, an optical analysis technique, to understand atomic or molecular composition because of its specificity, ease-of-use, and ability to provide insight into a product or process. Spectroscopic techniques in chemical analysis use light to probe the composition, structure, or concentration of substances. Spectroscopy techniques provided by Endress+Hauser include:

Raman spectroscopy – Detects molecular vibrations by analyzing scattered laser light, useful for identifying chemical bonds and structures.
Tunable diode laser absorption spectroscopy (TDLAS) – Uses laser light tuned to specific wavelengths to measure gas concentrations with high sensitivity.
Quenched fluorescence (QF) – Measures light emitted by excited molecules; quenched fluorescence tracks changes in luminescence intensity and decay to detect analytes like oxygen.
UV-Vis-NIR spectrophotometry – Measures reflectance, absorbance, and transmittance across ultraviolet, visible, and near-infrared wavelengths.
Infrared (IR) spectroscopy – Analyzes absorption of IR light to identify functional groups and molecular structures.
Atomic emission and absorption spectroscopy – Measures light emitted or absorbed by atoms to determine elemental composition.

These optical analysis techniques rely on the interaction of electromagnetic radiation with matter, making them powerful tools for both qualitative and quantitative chemical analysis.

What is Raman spectroscopy?

Raman spectroscopy is a powerful molecular spectroscopy technique that analyzes the vibrational modes of compounds and provides molecular fingerprint identification of materials through spectral analysis. It typically uses visible or near-infrared laser light as the source of electromagnetic radiation. The method measures the inelastic scattering of photons, known as Raman scattering, which occurs when light interacts with molecular vibrations. Unlike absorption-based techniques, Raman spectroscopy is based on scattering of light and does not require a defined path length. It is sensitive to changes in the polarizability of the electron cloud during light interaction, making it ideal for measuring symmetric bond vibrations. Like other molecular spectroscopy techniques, Raman spectroscopy is used to identify chemical composition and molecular structure. However, it offers important advantages, including its high specificity and ability to measure in aqueous samples. An aspect of Raman spectroscopy that is advantageous in a process setting is its ability to scale a quantitative analytical model from R&D to manufacturing with minimal scale-specific data.

What is ultraviolet-visible spectroscopy (UV/Vis)?

UV/Vis is an analytical technique that measures the absorption of ultraviolet and visible light by a substance. It operates within the wavelength range of approximately 200–800 nm and is commonly used to determine concentration, chemical structure, and purity of samples. UV/Vis analysis is widely applied in pharmaceuticals, environmental testing, and chemical research for fast, reliable results.

What is near infrared (NIR)?

Near-infrared (NIR) refers to the region of the electromagnetic spectrum with wavelengths ranging from approximately 780 nm to 2500 nm. NIR spectroscopy is widely used in optical analysis to identify chemical compositions, monitor material properties, and perform non-destructive testing. It is especially valuable in industries like hydrocarbon processing, pharmaceuticals, agriculture, and food processing for rapid, accurate analysis without sample preparation.

What is absorption spectroscopy?

Absorption spectroscopy measures the absorption of specific wavelengths of electromagnetic radiation by atoms or molecules in a sample. Absorption occurs due to the selective removal of certain frequencies by matter, revealing valuable information about the sample’s composition and concentration.

What is tunable diode laser absorption spectroscopy (TDLAS)?

TDLAS is a form of infrared spectroscopy that analyzes absorption related to changes in dipole moments of molecules during vibrational transitions. It uses infrared or near-infrared laser light tuned to a gas’s unique absorption lines to measure the concentration of specific analytes with high precision. The technique is governed by the Beer-Lambert Law, which relate the amount of light absorbed to the properties of the absorbing material. By applying Beer-Lambert Law, TDLAS quantifies how much light is absorbed at specific wavelengths, enabling accurate measurement of trace gases.

What is quenched fluorescence (QF)?

Quenched fluorescence (QF), also known as fluorescence quenching, is an optical technique that measures how the fluorescence of a molecule is reduced or "quenched” by oxygen. Fluorescence refers to the luminescence of light by an excited molecule almost immediately after it absorbs light. This method typically uses ultraviolet (UV) or visible light as the source of electromagnetic radiation. The technique involves the excitation and emission of light by fluorescent molecules, and the degree of quenching provides valuable information about the presence or concentration of specific analytes, such as oxygen.
