AA-7000 Series of Atomic Absorption Spectrophotometers ICPE-9800 Series of ICP Atomic Emission Spectrometers
In addition to high analysis sensitivity for target components, a flexible system In addition to high sensitivity to target components and the capacity for batch
configuration, compact installation space, and other user-friendly aspects have been analysis of multiple elements, these analysis systems feature a wide analysis
pursued. Attention has also been given to safety, with a vibration sensor included as concentration range. Wavelength selection for measurement elements as well as
standard, a world's first. spectral interference correction for coexisting elements, which have been highly
dependent on the skill of the operator, have been automated.

Headspace Analysis System The modules are centrally controlled by a system controller. Operation is easy, The atomic absorption method or ICP-AES method can be used depending on the target element.
As per the Interim Manual from the Ministry of the Environment (2007)
The outstanding core performance of the HS-20 headspace sampler and and highly reliable analysis results can be obtained. In terms of data processing,
