Environmental Forensics

Even just one drop of oil can result in making up to 600 liters of drinking water unsafe for human consumption. Sadly. every year immense amounts of hydrocarbons like used oil, lubricants and fuel are illegally dumped into the environment.

Exactly in such cases it is immensely important to determine the strength of the contamination as well as the origin of the respective hydrocarbon.

通过使用固相提取技术和FT-IR光谱，可以在现场进行这种分析，几乎立即瞬间，没有耗材或溶剂。

Release of toxic waste and hazardous chemicals into the environment, contaminating streams and waterways, causes immense damage to ecosystems and is dangerous to community health. Tracking down the origins of deliberate or accidental waste discharge is a key role of forensic water analysis and can require a rapid response approach to the collection and analysis of water samples taken from streams or groundwater bores.

Water analysis by traditional methods such as ICP-MS/OES is expensive due to the cost of instrumentation and consumables and can have long turn around times for results. An alternative approach is total reflection X-ray fluorescence (TXRF). Bruker's field deployableS2 PICOFOXand lab-basedS4 TSTAR提供小样品中常见水污染物的PPB水平检测，具有快速简单的样品制备。Bruker的水分分析解决方案快速提供高精度的结果，使释放到环境中的有毒废物的快速检测和表征，允许持责任缔约方被逮捕并实施努力。

土壤法医分析涉及多个领域的集成，以表征土壤，以促使刑事调查的目的。不同的土壤特征可能有助于调查人员了解犯罪现场，无论是否发生了埋葬，甚至保留了人类遗骸的痕迹。法医土壤分析的一个方面涉及指纹土壤的成分来导出土壤来源，将其连接到特定地理位置。

指纹土壤的方法包括矿物颗粒的元素表征和其他可以存在于法医样品中的颗粒物质。布鲁克的M4 TORNADOallows rapid analysis of minimally prepared samples without the need for a conductive coat; samples may be scattered on carbon tape and quickly scanned. With a spot size down to <20 um, even small mineral grains are detected. Elements measured in each grain allow easy identification of the minerals present and their relative abundances. Where collected due to transfer – on a shoe or on clothing – these data can be used for direct comparison to samples taken at crime scenes or to databases of common regional soil types.

The detection, identification and quantification of leaks of certain toxic gases and vapors in chemical plant and in chemical transport have proved to be a challenge. Yet, technologies that meet these requirements have existed for several years, and provide rapid and accurate determination of specific toxic gas and vapors in ambient air.

In this field, two techniques stand out as excellent solutions. Ion Mobility Spectrometry (IMS) provides ultra-high sensitivity to a specific range of highly toxic chemicals, being generally applied to the detection of substances at specific points in a chemical plant.

Infrared spectroscopy (IR) is a technique that is also well suited to the detection of a broad range of toxic gases and vapours, and system offered by Bruker is designed for the volumetric detection of toxic pollutants over a broad area.

Detect the following gases (and more) in air down to low parts per billion levels:

• 氯，氨，二氧化硫
  
• 氰化氢和碱金属氰化物（如HCN）
• Chloro-organic compounds
• 甲苯二异氰酸酯（TDI）
• 二甲基硫酸盐（DMS）

The accuracy, speed, reliability and sensitivity of the Bruker detection instruments can help to eliminate long shut down periods in production, by helping to detect and locate leaks quickly.

此外，当目前使用的技术需要数小时时，它们在危险气体中，他们的快速反应在保护工人和危险气体中的危险气体中的迅速作用起着至关重要的作用。

Bruker detectors can even pay for themselves by preventing one major factory incident and will operate for years; improving operator well-being and increasing productivity.
