Currently, measurements for concentration of formaldehyde is done most commonly by absorptiometric method or HPLC (high performance liquid chromatography) method.
However, these methods require expensive devices, knowledge and experience.
Furthermore, in detector tube method which is effective as a simple measurement, up to this date it had been impossible to detect and measure the trace amount of formaldehyde at the indoor pollution level.
With Air sampler S-21, this newly developed detector tube is capable of measuring within the range of 0.01 - 1.2ppm.
And it covers the indoor environment suggested value by WHO, which is 0.1mg/m3 (0.08ppm 30min average).
