Selection 7 Environmental Analysis
Analysis of Multiple Elements in Drinking Water by ICPE-9820
Conducting safety inspections for drinking water is the responsibility of each country according to their respective regulations. Typically, there
are many target elements included in the test, such as N, Ca, etc., which are present at the mg/L level or greater, and toxic trace elements
such as Pb and Cd, which are normally present at the µg/L level or less. Here, using the Shimadzu ICPE-9820 multi-type ICP atomic emission
spectrometer and an ultrasonic nebulizer, we conducted analysis of river water, typically the source of tap water.

Selection 8 Environmental Analysis
Analysis of Heavy Metals in Sewage Sludge and Sewage by ICPE-9820
In recent years, the increase of sewage sludge generated in the sewage treatment process has become a problem. For the purposes of waste
reduction and recycling, following incineration, sewage sludge is being re-used as cement material, civil engineering material, fertilizer, etc. However,
the reuse of sewage sludge, from the standpoints of environmental protection and potential health hazards, requires that its toxic heavy metal
content is carefully examined. Here, using the Shimadzu ICPE-9820 multi-type ICP atomic emission spectrometer, we conducted analysis of processed
water from a sewage treatment plant, in addition to sewage sludge ash.

Selection 9 Environmental Analysis
Content Analysis of Toxic Elements in Soil by ICPE-9800 Series
Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely
affects health when the soil itself is directly ingested. Therefore, assessment of soil toxicity using a defined method is required. The apparatus
used for the analysis is required to accurately measure those elements at trace concentrations equivalent to or lower than the reference values.
Here, using the Shimadzu ICPE-9800 series multi-type ICP atomic emission spectrometer, we conducted content analysis of soil.

Selection 10 Environmental Analysis
High-Speed X-Ray Diffraction Analysis of Asbestos (Chrysotile) Using Wide-Range High-Speed Detector
Asbestos is a material that has long been widely used as a building material due to its excellent heat and acid resistance. However, its
use has gradually been banned because of widespread recognition of its adverse health effects. Here, we introduce an example of
high-speed quantitative analysis of chrysotile, one kind of asbestos, using the new OneSight wide-range high-speed detector.

Selection 11 Environmental Analysis
Quantitative Analysis of Pyrethroids in Soil Using Triple Quadrupole LC-MS/MS
Pyrethroids are insecticides used worldwide for both household and farming applications. Traditionally, pyrethroids are measured by Gas
Chromatography with or without mass spectrometry. Here, we present a method using LC-MS/MS to show that LC-MS/MS can measure
these compounds traditionally analyzed by GC. This report illustrates a simultaneous analysis of 15 pyrethroids using the Shimadzu
LCMS-8050 with ultrafast polarity switching.

Selection 12 Environmental Analysis
High Speed Analysis of Haloacetic Acids in Tap Water Using Triple Quadrupole LC-MS/MS
Haloacetic acids (HAAs), by-products of water disinfection, are formed from naturally-occurring organic and inorganic materials in water
that react with the disinfectants chlorine and chloramine. A LC-MS/MS method, which is capable of direct injection of water samples, for
measuring HAAs has been developed to replace previously used methods requiring tert-butyl-methyl ether liquid extraction and
diazomethane derivatization prior to GC analysis, thus reducing the effort required for sample preparation.

Selection 13 New Technology
Structural Analysis of Glycosphingolipids by LC-IT-TOF-MS
A method for detection and structural characterization of glycosphingolipids (GSLs) based on LC-IT-TOF-MS is introduced and the results
of analysis of GSLs containing sialic acid in mouse thymocytes, CD4T and CDT8 cells are described as an example of its application. Even
at trace levels and in a mixture, both carbohydrate chain and lipid structures were characterized, and previously unknown information
could be obtained. The development of a new analytical tool is in progress and applicable future challenges are discussed.
