About Edinburgh Instruments Ltd

Founded in 1971 by Professor S. D. Smith OBE FRS, FRSE, FinstP, Edinburgh Instruments Ltd has become one of the world’s largest manufacturers of leading edge spectroscopic instrumentation and gas detection solutions.

We were formed as the first spin-out from Heriot-Watt University and were the first private company on Britain’s first University “Research Park”.

Edinburgh Instruments (EI) is now located across three buildings totalling nearly 30,000 sq. ft. of manufacturing and office space just outside Edinburgh, where it employs over 75 people. The company is involved in the development, manufacture and sale of a wide range of high technology products for the scientific research and industrial markets. Product ranges include lasers and analytical spectrometers supplied by the Photonics Division and gas detection and monitoring products supplied by the Sensors Division.

Following rapid expansion, by the 1980s a full range of infrared and far infrared gas lasers (CW and pulsed CO2 and CO lasers and optically pumped TeraHertz lasers) were made available to the market.

As pioneers of Time-Correlated Single Photon Counting (TCSPC), in 1978 the company developed a Fluorescence Lifetime Spectrometer system based around the successful nanosecond flashlamp. This product range has culminated in the development of the FLS980, the latest computer controlled, combined Steady State and Fluorescence Lifetime Spectrometers on the market and the FS5 one of the world’s most sensitive benchtop spectrofluorometers.

Product diversification continued with the development of CO, CO2 and CH4 gas sensors. Based on interference filter based non-dispersive infrared technology these devices are available as OEM cards or complete monitoring and detection packages, supplied through the Sensors Division.

EI products are used in an extensive range of markets and applications, including: photo-chemistry, physics, protein studies, biochemistry, biophysics, molecular spectroscopy, optical pumping, interferometry, plasma diagnostics, atmospheric studies, materials processing, solid state physics and material science, renewable energy, climate control environments, process control and much, much more.

Over the years EI has continually diversified and developed new and innovative products, winning many international designs, technology and export achievement awards. We excel in providing one-to-one comprehensive customer service and continue to meet the needs of our customers worldwide.

In 2013, EI was acquired by Techcomp Europe Ltd, a group of European companies involved in the manufacture and distribution of analytical systems, life science equipment and laboratory instruments with operations dating back to 1920.

As well as Edinburgh Instruments, the Group comprises; Scion Instruments – (with operations in The Netherlands, California and Shanghai) experts in Gas Chromatography, Analysers and Single Quadrupole Mass Spectrometry, Froilabo – (with factories in France and Romania) specialising in Ultra Low Temperature technologies, Precisa – (manufacturing in Switzerland) offering a complete range of high precision metrology and weighing solutions and Dynamica – (based in the UK) that supplies a wide range of analytical and laboratory instruments. Techcomp Europe is owned by Techcomp (Holdings) Ltd whose ordinary shares are traded on the Stock Exchange of Hong Kong Limited (SEHK) as stock code 1298.

About Edinburgh Instruments Ltd

Providing state‐of‐the‐art steady state and time‐resolved luminescence measurements to the global research and analytical markets, Edinburgh Instruments has a solution for almost every spectroscopic need using a variety of techniques.

Time-Resolved Fluorescence
Time-Resolved Fluorescence (or Fluorescence Lifetime) Spectroscopy is an extension of Steady State Fluorescence. Fluorescence lifetimes, occurring as emissive decays from the singlet-state, can also be approximated as those decays occurring in the time region from picoseconds to nanoseconds.

When we discuss time-resolved fluorescence or fluorescence lifetimes, what we are studying is the fluorescence of a sample monitored as a function of time after excitation by a pulse of light.

Steady State Fluorescence

Steady-State Fluorescence Spectroscopy investigates the long-term average fluorescence of a sample when irradiated with UV, Visible or near-IR Light.

Edinburgh Instruments offers a range of research-grade and analytical Steady State Spectrofluorometers. These vary in a number of ways but can be compact, benchtop or modular, and fully customisable for any type of fluorescence measurements that will meet the most demanding research requirements.

Phosphorescence Lifetime

Phosphorescence lifetimes, occurring as emissive decays from the triplet-state, can also be approximated as those decays occurring in the time region from tens of nanoseconds to seconds.

Phosphorescence lifetime measurements are carried out using a technique called Multi-Channel Scaling (MCS) and this is used for the acquisition of sample decays.

Transient Absorption

Transient Absorption / Laser Flash Photolysis is a technique for studying transient absorption of chemical and biological species generated by a short intense light pulse from a pulsed laser source (‘pump source’).

This intense light pulse creates short lived photo-excited intermediates such as excited states, radicals and ions. All these intermediates are generated in concentrations large enough for chemical and physical interaction to occur and for direct observation of the associated temporally changing absorption characteristics. These absorption changes are recorded using a spectrally continuous Xenon lamp (‘probe source’) forming the background in a single beam absorption spectrometer. The probe source is operated in a pulsed mode to enhance the photon flux for measurements in short time ranges.

Raman Spectroscopy

Raman Spectroscopy is a non-destructive technique that is used for the identification and quantification of chemical composition. When combined with an optical microscope, Raman spectroscopy is more sensitive, less affected by unwanted background interactions, and offers the spatial resolution required for chemical mapping.

UV-Vis Spectroscopy

UV-Vis Spectroscopy is a quantitative technique used to measure how much a chemical substance absorbs light. This is done by measuring the intensity of light that passes through a sample with respect to the intensity of light through a reference sample or blank. This technique can be used for multiple sample types including liquids, solids, thin-films and glass.

Combined Techniques

Edinburgh Instruments manufacture precision instrumentation that can carry out a variety of different types of fluorescence and measurement techniques.
