Continuous Dichotomous Aerosol Chemical Speciation Analyzer

【Continuous Dichotomous Aerosol Chemical Speciation Analyzer】

Intelligence Data Logger
It is the evolutionary continuous dichotomous analyzer that can measure the chemical species in the atmospheric aerosol (PM2.5 and PM10-2.5) while measuring the mass concentration every one hour, automatically.

Continuous Dichotomous
Aerosol Chemical Speciation Analyzer

Features
1
ACSA enables to minimize artifact during sampling and matrix effects (interference) during analyzing by the short period (every 1 hour) sampling with using a PTFE tape filter and a virtual impactor. It is non-conventional approach to measure "the acidity of atmospheric aerosol", which has been difficult to measure precisely using 24-hour sampling method because of gas adsorption or particulate volatility.

2
To measure mass concentrations simultaneously enables to compare with environmental standards and to estimate the contribution of chemical species or amount of water in PM2.5.

3
The highest sensitivity can be obtained by concentrating the aerosol in 1 m3 air to 1 mL solution with PTFE tape filter and automatic extraction system, in comparison with the aerosol-mass-spectrometer (AMS) and the continuous sulfate/ nitrate analyzer.
