Analytical solutions for artificial photosynthesis

16 May 2024

Artificial photosynthesis is a technology that uses photocatalysts and sunlight to convert light energy into useful compounds, and is considered a next-generation renewable energy technology. Shimadzu Corporation explains the challenges in implementing artificial photosynthesis into society, and the need to develop photocatalysts that can effectively utilize sunlight and construct high-efficiency reaction systems. Shimadzu also highlights analytical techniques, focussing on the evaluation of physical properties, excited state, measurements, and quantification of reaction products, including band gap measurement, particle size distribution measurement, charge distribution visualization, and gas chromatography mass spectrometry analysis. Explore the benefits and applications for each analytical technique, as well as detailed descriptions of the products and equipment used.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Renewable EnergyGreen Labs
