Selection 7 Biomass
Characterization of Algae by TOC Measurement
Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other
biofuels, its productivity per unit time and area is high, while arable land selection possibilities are great. Here, we introduce an
example of a unique application in which the TOC-LCPH total organic carbon analyzer is used to characterize microalgae by
directly measuring, without conducting any pretreatment, the TOC content in a suspended culture of microalgae cells.

Selection 8 Biomass
Measurement of TOC and TN in Marine Water Algae Culture Solution
The culturing of microalgae in various types of non-edible biomass has received considerable attention in recent years. Here, we
introduce an example of the simultaneous measurement of TOC and TN in seawater using the TOC and TN measurement system
consisting of the TOC-LCPH total organic carbon analyzer for microalgal biomass measurement and the TNM-L unit for total
nitrogen measurement.

Selection 9 Energy
Tracera (GC-BID) Solution
The Tracera GC System utilizes Barrier Discharge Ionization Detector technology coupled with a GC-2010 Plus capillary gas
chromatograph to create a GC system that makes it possible to reveal trace components that are difficult to see by other GC
detectors. Shown here are 12 examples of applications using Tracera in a variety of fields such as artificial photosynthesis,
coal-based chemical synthesis, etc.

Selection 10 Fuel Cell
Trace Impurity Analysis of Hydrogen Fuel in Fuel Cell Vehicle-Related Fields
With the development of fuel cell technology for electricity generation using hydrogen as fuel, attention is turning to household fuel
cell systems and fuel cell vehicles. Here we introduce an example of high-sensitivity analysis of carbon monoxide in hydrogen and
simultaneous analysis of impurities in hydrogen using the Tracera high-sensitivity gas chromatograph equipped with a BID detector.

Selection 11 Fuel Cell
X-Ray CT Observation of Fuel Cell MEA
Fuel cells are devices that convert the energy obtained from an electrochemical reaction of hydrogen fuel directly into electrical
energy. Because they are highly efficient and emit only water, fuel cells have attracted great interest due to their potential for
contributing significantly to providing a solution for both energy and environmental concerns. This Application News bulletin
provides an example of using an X-ray CT system for fuel cell observation.

Selection 12 Lithium-ion battery
X-Ray CT Observation of Lithium-Ion Battery Electrodes
Today, rechargeable lithium-ion batteries are widely used in a variety of fields and are available in a wide range of shapes,
capacities, and applications. X-ray CT systems are able to non-destructively observe the internal structure of items, and can
therefore be used to analyze defective batteries, evaluate changes in the internal structure of batteries during cycle testing, etc.
This application demonstrates how the inspeXio SMX-100CT can be used for detailed observation of the electrode structure in
rechargeable lithium-ion batteries.

Selection 13 Solar Cell
Measurement of Transmittance of Solar Battery Glass
-Measurement of Transmittance of a Light Scattering Solid Sample-
When measuring a solid sample with strong light scattering properties, using a 60 mm diameter integrating sphere can result in a
change in photometric values at wavelengths where the detector is changed. We introduce an example measurement of the
transmittance of solar battery glass that is strongly light scattering, where the change in photometric values is prone to occur.

Selection 14 Chemiluminescence
Measuring Peroxyoxalate Chemiluminescence Using a Spectrofluorophotometer
Chemiluminescence based on using oxalate esters features high-emission efficiency and long emission time and provides
illumination for long periods without any electricity. Consequently, it is used for recreational, fishing, and many other applications
where it is commonly called glow sticks. The following describes the luminescent process of peroxyoxalate chemiluminescence and
gives an example of using an RF-6000 spectrofluorophotometer to measure the emission spectra of glow sticks.
