美國inXitu
inXitu公司是一家領先的便攜式X射線/ X射線熒光光譜儀器設備。 專注于開發所需的技術 ， 使新一代的科學儀器 ， 用于文物、藝術品鑒定，材料分析。

InXitu公司的“Duetto”儀器是第一款市面上有售的結合XRD/XRF(X射線衍射/X射線熒光功能的儀器，它可用于在原位置對物質進行礦物/相位和元素分析。Duetto完美地適用于需要對物品進行無損分析分析的場合，例如藝術品，法醫學或體積過大難以帶入實驗室進行傳統的X射線衍射和/或X射線熒光分析的物品。通過使用以2D X射線衍射(XRD)和能量分散X射線(XRF)為基礎的成熟的影像技術，Duetto能夠提供與實驗室儀器高度相關的分析。
inXitu Inc. is a leader in portable XRD/XRF based instrumentation. We specialize in developing the technologies required to enable the next generation of scientific instruments used for materials analysis. The technology used in our portable rock and mineral analyzer received a prestigious R&D 100 award and was chosen to fly on the Mars Science Laboratory rover scheduled for launch in 2009.

Our powder handling methods can dramatically improve the quality of your XRD data while reducing the requirements for sample preparation. inXitu’s patented technique makes possible quality XRD data to be collected regardless of the grain size of the sample. Grain sizes up to 400 um have been tested producing data normally obtained with micron size particles.

Incorporating key technologies from our portable XRD instrument and advanced sample handling techniques, we are currently developing solutions targeted for identification and analysis in the areas of explosives, pharmaceuticals, forensics, art and archaeological materials. This new line of instruments will offer performance comparable to laboratory XRD systems with the benefit of portability, significantly reduced sample preparation and reduced cost.
