            •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
            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
            products, soil environments, and wastewater.
            The ICP and AA analysis methods are
            effective for measuring elements of 1-ppm
            (µg/g) level in solid samples, such as
            plastics.                                                                        ■Analysis of cadmium in plastics
