T. Yarita; S. Inagaki; A. Miyamoto; T. Yamazaki; M. Kawaguchi; H. Uchida; A. Takatsu; T. Suzuki, 筆頭著者, A scallop midgut gland certified reference material, NMIJ CRM 7520-a, was developed for validation and quality assurance during the inspection of shellfish for diarrhetic shellfish toxins. The candidate material was prepared by using naturally-toxic and nontoxic boiled midgut glands spiked with okadaic acid (OA). The homogeneity and stability of the material were found to be appropriate. For the characterization of OA and dinophysistoxin-1 (DTX1), nine participants were involved in a co-laboratory study based on the Japanese Official Testing Method, where the compounds were assayed by liquid chromatography-tandem mass spectrometry following alkaline hydrolysis. The analytical values were obtained by the standard addition method with a standard spiking solution calibrated using the standard-solution certified reference materials OA and DTX1. The certified concentrations with expanded uncertainties (coverage factor k = 2, approximate 95% confidence interval) were determined to be (0.205 ± 0.061) mg/kg for OA and (0.45 ± 0.11) mg/kg for DTX1., Elsevier

保母敏行; 村山真理子; 浅田正三; 井垣浩侑; 鎗田孝; 石橋耀一; 鶴田暁; 松本保輔; 柿田和俊; 小野昭紘; 坂田衛, The Japan Society for Analytical Chemistry has developed two new certified reference materials (CRMs) for dioxins : coplanar PCBs and 1∿10 chlorinated PCB homologues. A project team has been organized to prepare 2 kinds of marine sediment and to certify the concentration of dioxins and polychlorobiphenyls. An interlaboratory comparison test was performed by participants from 24 laboratories. In a statistical analysis, the z scores in robust method were applied to reject outliers, followed by the usual statistical procedure. The presented CRMs are expected to be useful for the quality assurance and quality control of dioxins analysis., 日本分析化学会

中島良司; 鎗田孝; 渋川雅美, 責任著者, GCの検出法の一つであるFIDをSWCに適用し,アルコール類の分析を行った.SWCからの溶出液はその一部をスプリットし,溶融シリカキャピラリー管を介してFID装置へ導入した.本法におけるFIDの操作条件,すなわちFIDノズル内のキャピラリー管の先端位置,及び水素とヘリウムの流量を最適化した.最適条件でのメタノール,エタノール,1-プロパノール,1-ブタノール及び1-ペンタノールの検出下限値(S/N=3)は,26～57 ngの範囲であった.また, n-アルコールの保持はカラム温度の上昇に伴い減少し,移動相圧力の増加に伴い増加することが明らかとなった.本法をワイン中のエタノールの分析に適用し,GC/MSによる測定値との比較を行った結果,両法により得られた測定値はよく一致した., 日本分析化学会
