Shimadzu provides a wide variety of evaluation instruments to assist in, for example, the
Substances evaluation and management of additives that influence the performance and properties of
polymer materials. We also offer instruments for the quantitative analysis of harmful
substances, which have become a major point of concern recently because of the effect on
public health.
■Chromatogram of tire rubber
•GCMS-QP2010 Pyrolisis Measurement System (for testing rubber and plastic additives)
■Analysis of phenolic antioxidant
Polymer compounds, such as plastics, rubber, and resin, are thermally decomposed at temperatures greater than 500°C and the products are •High-performance Liquid Chromatograph LC-VP System
analyzed using GC-MS. These products reflect the structure of the original polymer compounds and so they can be used to perform polymer Performs high-sensitivity quantitative determination of additives, such as plasticizers and antioxidants, with a high degree of accuracy.
identification and high-order structure analysis. Database search software is also available to assist with polymer identification.
■Analysis of components dissolved in polymers
•GCMS-QP2010 Headspace Analysis System (for testing residual solvents in polymers)
The analysis of solvents and volatile components in solids is possible using the headspace. Volatile components, especially those with low
boiling points, can be found in the upper region (i.e., the “headspace”) of liquids and solids. The headspace sampler is a device that obtains
■Simultaneous analysis of aldehydes and ketones
samples of a fixed amount at a fixed temperature and injects them into the GC-MS instrument. This system can be used for the measurement of
volatile components in polymers and packing materials and for the qualitative and quantitative analysis of odors given off by chemical products. •High-performance Liquid Chromatograph LC-2010 Formaldehyde Analysis System
A system that analyzes the formaldehydes given off by sheet building materials used to decorate walls and floors. Operation is completely
automatic to ensure easy analysis.
•Inductively Coupled Plasma
■Analysis of Cu in polymers
Spectrometer ICPS Series
The ICP (inductively coupled plasma) and AA
(atomic absorption) analysis are methods for
measuring the element concentration in
samples at the micro level with a high level of
accuracy. They can be used for a wide
variety of samples in a number of different
areas, such as rubber, plastics, materials for
electrical components, pharmaceuticals, food
•Atomic Absorption Spectrophotometer AA-6800/6300 products, soil environments, and wastewater.
The ICP and AA analysis methods are
This spectrophotometer is very effective for the measurement of heavy metals (e.g., cadmium and lead) in
effective for measuring elements of 1-ppm
rubber and plastics and for the measurement of silicon deposits. It is widely used for a variety of different

purposes, such as Pharmacopoeia, and Food Sanitation Law and Standard Methods of Analysis for Hygienic
plastics. ■Analysis of cadmium in plastics
