Various samplers for collecting various chemical compounds and new standard chemicals needed for new analytical methods
Various samplers for collecting various chemical compounds and new standard chemicals needed for new analytical methods
We have developed the various diffusive samplers; DSD-DNPH, DSD-BPE / DNPH, DSD-TEA; for collection of chemical compounds in the air, and these samplers are commercially available by Sigma-Aldrich (Merck).
As active sampling device, BPE-DNPH Cartridge, CX-572 cartridge was developed for collection of chemical compounds in air, and these samplers are commercially available by Sigma-Aldrich (Merck).
In addition, new standard chemicals for new analytical methods are commercially available by Sigma-Aldrich (Merck).
The DSD-DNPH diffusive sampler is adopted to the official method of OSHA (US Safety and Health Administration) Method 1007.
The CX-572 cartridge is adopted to WHO's official method, standard operating procedure, SOP-08, SOP-09.
The DSD-BPE/DNPH diffusive sampler has been used for nationwide surveys of indoor air quality in Japan.
