Selection 1 Artificial Photosynthesis
QYM-01 Photoreaction Quantum Yield Evaluation System
The QYM-01 photoreaction quantum yield evaluation system permits accurate and easy quantitation measurements of absorbed
photons when excitation light is irradiated onto a sample. The QYM-01 is the ideal system for in situ measurement of
photochemical reactions and internal quantum yield evaluation of homogeneous photocatalysts.

Selection 2 Artificial Photosynthesis
High-Sensitivity Analysis of Formic Acid Using GC-BID in Artificial Photosynthesis Research
Artificial photosynthesis refers to a technique of creating high-energy materials using photocatalysis and solar energy, and is
expected to play a role in the development of next-generation renewable energy. This Application News introduces an example in
which the GC-BID is used for analysis of formic acid in an actual sample consisting of the solvent N ,N-dimethylacetamide, used in
the research of artificial photosynthesis.

Selection 3 Biomass
Analysis of Biomass Using Organic Acid Analysis System
Industrial production of bioethanol from biomass resources involves a process in which cellulose and hemicellulose in the biomass
are decomposed using diastatic enzymes to be converted to monosaccharides such as glucose or xylose, which are then converted
to ethanol by the action of yeast. Here, we introduce an example of the simultaneous analysis of acetic acid, formic acid, furfural,
and 5-hydroxymethyl furfural, typically present in the biomass, using a combination of an organic acid analysis system together
with an ultraviolet-visible spectrophotometric detector.

Selection 4 Biomass
Analysis of Organic Acids in Culture Medium Using Post-Column pH Buffering Organic Acid Analysis System
The shift from an emphasis on fossil fuels in recent years has been emphasized with increasingly active research into the
bioproduction and manufacture of new energy sources and chemical products. Here, we introduce an example of analysis of
organic acids in a culture medium using post-column pH buffered electrical conductivity detection in combination with a dual
column oven, a system that provides both improved separation and high-selectivity detection.

Selection 5 Biomass
Simple Quantitative Measurement of Nannochloropsis Micro Algae in Water Using Shimadzu UV
Micro Algae Analysis System
In studying micro algae, measurement of the daily growth (concentration) is important. Currently, this measurement is conducted
by the dry weight method, in which the sample is filtered using filter paper, and then dried prior to weighing. Here, we introduce
Shimadzu's newly developed UV micro algae analysis system which permits simple measurement of the micro algae concentration
using a spectrophotometer.

Selection 6 Biomass
Monitoring of Algae Growth by TOC Measurement
This presents an example of a unique application in which the TOC-LCPH total organic carbon analyzer is used to track the growth
process of microalgae by directly measuring, without conducting any pretreatment, the TOC content in a suspended culture of
microalgae cells.
