S2 PICOFOX
現場 での元素分析
結果までの最短時間
S2 PICOFOX - スマート、グリーン、コンパクト
S2 PICOFOXは、超微量元素分析用の可搬型全反射XRF装置です。ガスや冷却媒体から完全に独立しているため、実験室だけでなく、現場での分析にも使用することができます。
- ハロゲン化物を含む多元素の微量同時分析
- ナノグラムからマイクログラムの微量サンプルの分析が可能
- 毎日の校正が不要で、内部標準を用いた簡易定量が可能
- 様々なサンプルタイプやアプリケーションに対応
- マトリックス効果やメモリー効果がない
- 低ランニングコスト、媒体、消耗品、定期的なメンテナンスが不要
EDXRF分光計と比較したTXRFの利点
S2 PICOFOXの動作原理は、全反射蛍光X線（TXRF）分析に基づいています。単色放射と全反射光学系の使用により、S2 PICOFOXは以下のようなメリットをもたらします。
- サンプルマトリックス中の吸収や散乱の影響を低減し、内部標準化による容易な定量を可能にします。
- 検出器と試料の距離が近いため、蛍光収率が向上します。
- バックグラウンドの低減により、検出限界は数桁低くなります。
- 液体や粉体など、極微量の試料でも高精度に定量できます。

Accessories to Help Avoid Contamination during TXRF Sample Preparation
When detecting samples at ultra-low ppb limits contamination avoidance is of the highest priority – when working with a pure sample the key to this is excellent sample preparation.
Bruker provides a range of accessories alongside their S4 T-STAR and S2 PICOFOX systems.
These include a T-BOX to help achieve contamination-free and accurate sample pipetting and the T-DRY for the vacuum desiccation of samples; with both being designed to help users avoid making any contact with the sample carrier.
Following the collection of measurements, the sample disks can be efficiently and effectively cleaned for later use using Bruker’s chemically resistant washing cassette before clean storage in the T-BOX.
