Abstract
Description
a)トレーサー化合物を、前記少なくとも1つの原液成分を含む既知液体組成物に添加して、タグ付けされた既知液体組成物を形成する工程と;
b)未確認の液体組成物のサンプルを得る工程と
c)所望により、未確認の液体組成物の前記サンプルを、液体と混合することにより希釈する工程と;
d)前記所望により希釈された未確認の液体のサンプルを、金、銀または銅を含む分光増強表面(spectroscopy-enhancing surface)と接触させる工程と;
e)サンプルからラマンスペクトルを得る工程と;
f)前記スペクトルから、未確認組成物のサンプル中の前記原液成分の濃度に対するトレーサーの濃度を計算する工程と;
g)タグ付けされた既知液体組成物のトレーサー及び原液成分の対応する相対濃度とfで計算した相対濃度を比較する工程と
を含む。
130μlの銀コロイド及び130μlの高純度水を(96ウェルプレートの)ウェルに添加し、完全に混合した。100ppb w/v(10−7M)のトレーサー化合物を含有するタグ付けされた殺虫剤のサンプル30μlをウェルに添加した。ウェルプレートの内容物をピペット吸引によって完全に混合した。次に、10μlの0.01Mスペルミンを混合物に添加し、混合した。次に、532nm励起波長で5×対物レンズを用いるRenishaw(商標)inViaラマンマイクロスコープを用いて、SERS測定をサンプルで実施した。
食品への添加が承認された化合物の現在のリストから選択される、ラマン活性トレーサー化合物を用いて市販の農薬製剤をタグ付けした。100mg/lのラマン活性トレーサー化合物を含有する溶液を脱イオン水中に調製した。この溶液の一部を使用して、0mg/l〜5mg/lの範囲の農薬製剤中のラマン活性化合物濃度で農薬製品のサンプルをタグ付けした。
ラマン活性トレーサー化合物を用いて市販のツヤ消し白色塗料をタグ付けした。4mg/lのラマン活性化合物を含有する溶液を脱イオン水中に調製した。この溶液の一部を使用して、0mg/l〜50mg/lの範囲の塗料中ラマン活性化合物濃度で塗料のサンプルをタグ付けした。
水溶液中32.5重量%の尿素を含有するディーゼル排気流体のサンプルが、タグ付けする製品であった。ラマン活性トレーサー化合物を、1.1×10−6Mのトレーサーの終濃度が得られるようにディーゼル排気流体に添加した。ディーゼル排気流体は、事前に希釈することなく以降の分析で使用した。
