S2 PICOFOX
现场元素分析
短时间内迅速获得准确结果
S2 PICOFOX - 智能、环保、轻巧
S2 PICOFOX 是一种移动式（可现场流动测样）全反射X射线荧光光谱仪，用于超微量元素分析。该备在使用中无需消耗气体，无需冷却介质，该分析仪不仅可用于实验室，还可用于现场分析。
- 同时进行多元素定量分析，包括卤化物
- 测试所需样品量极少
- 使用设备标样自动校准，无需每日校准
- 适用于各类样品
- 无基体效应
- 低运营成本，无需定期维护，使用中无需任何耗材以及冷却介质
与传统 EDXRF 相比，全反射X射线荧光光谱仪具有以下优势
S2 PICOFOX 工作原理基于全反射X 射线荧光 （TXRF）对样品进行 分析。使用单色仪和全反射光路设计使得 S2 PICOFOX 具有以下优点：
- 减少样品基体吸收和散射效应， 通过加入内标轻松实现定量分析。
- 缩短探测器到样品距离 促使荧光产量增强。
- 由于背景的减少，检测低限可降低几个数量级。
- 极少量的液体和粉末也可以精确定量。

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 S2 PICOFOX and S4 T-STAR 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.
