Nickel(ii ) chloride hexahydrate (NiCl2·6H2O), tin(ii ) chloride dihydrate (SnCl2·2H2O), active carbon (SBET = 815 m2 g−1), MgO, and commercial aluminum hydroxide (c-AlOH) were purchased from WAKO Pure Chemical Industries, Ltd. and used as received unless otherwise stated. g-Al2O3 (SBET = 100 m2 g−1) was purchased from Japan Aerosil Co. Furfural (98%), furfuryl alcohol (97%), 2-methylfuran (98%), and tetrahydrofurfuryl alcohol (99%) were purchased from Tokyo Chemical Industry, Ltd. All organic chemical compounds were purified using standard procedures prior to use.55
Active carbon
Manufactured by Fujifilm
Sourced in Japan
Active carbon is a porous, high-surface-area material derived from carbon-rich materials. Its core function is to adsorb a wide range of organic and inorganic compounds from various media, including air and water.

COS test
gases were prepared by dilution of
standard cylinder gas (100 ppm COS balanced with nitrogen, Japan Fine
Products, Kawasaki, Japan) with purified air using mass flow controllers.
Gas dilutions (uncertainty of the first step dilution accuracy was
within 2.7%) were conducted twice to obtain ppbv levels of COS. The
gas absorbing solution was 0.1 M NaOH with the addition of 1 or 5
μM FMA. FMA was purchased from Sigma Aldrich (St. Louis, MO).
A molecular sieve 3A (pore size 30 μm, 1/8″, Nacalai
Tesque, Kyoto, Japan, or 80/100 mesh, Shimadzu, Kyoto, Japan) was
used for selective H2S removal. A minicolumn packed with
soda lime No.2 (Wako Pure Chemical, Osaka, Japan) and active carbon
(Nacalai) was used to remove H2S produced by hydrolysis
of COS to obtain a baseline signal. Alumina catalyst NT-9710 (50 m2/g) was obtained from Nissan Girdler Catalyst (Tokyo, Japan).
A silanizing agent (L-25, Fuji Systems, Tokyo) was used to make the
gas channels inactive.

Native congeners of PCDDs, PCDFs, dioxin-like PCBs, and non-dioxin-like PCBs were purchased from Wellington Laboratories (Guelph, Canada). [13C12]–congeners of PCDDs, PCDFs, dioxin-like PCBs, and non-dioxin-like PCBs as internal standards, were also purchased from Wellington Laboratories. An active carbon column was prepared as follows: active carbon was purchased from Nacalai Tesque (Kyoto, Japan), refluxed 3 times with toluene for 1 h, and dried in vacuum, after which 500 mg of the active carbon was mixed with 500 g of anhydrous sodium sulfate (Wako Pure Chemical Industries, Ltd., Tokyo, Japan). A silver nitrate/silica gel was purchased from Wako Pure Chemical Industries, Ltd. All reagents and solvents used in this experiment were of the analytic grade of dioxin that is commercially available.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
