"転写サンプリング" により、質量分析のアプリケーションを拡大します
Poropare™ 転写プレート A15551シリーズは、浜松ホトニクスのもつ独自のガラス成形技術と成膜技術により実現した、質量分析用の前処理サポートアイテムです。堅牢性のあるポーラス構造とイオン化支援層により、質量分析の前処理の簡便化に貢献します。
特に、従来では当たり前の試料薄切を不要とした「転写」サンプリングの実現は、質量分析イメージングの適用範囲を大きく広げます。

試料の測定面をPoropareの有効面に押し付ける(転写)だけで前処理は完了です。最大のハードルである薄切が不要になると同時に、有効面にあるイオン化支援層がマトリックスフリーの測定を実現します。

誰でも簡単!
Poropareを用いない測定では、薄切のための専用装置(クリオスタットなど)が必要で、測定準備が大変です。また、測定できるサンプルも、凍結や薄切が可能なサンプルに限定されます。
