热烈庆祝WITec公司成立20周年!

自1997年成立至今,在从乌尔姆大学物理系毕业的3位公司创始人的努力下,公司不断发展壮大,目前全球拥有60名员工,除德国乌尔姆总部外,分支机构分设在西班牙、美国、中国、日本和新加坡。正如公司价值观“Focus Innovations”所体现,WITec的成功源于不断引进新技术并坚持以高质量、灵活强大的产品提升客户满意度。

20年来,WITec已经成长为世界知名的共聚焦拉曼成像系统制造商,也充分体现着德国品质的内涵。WITec的第一套设备——扫描近场光学显微镜(SNOM/NSOM)至今还在稳定高效地运转,伊利诺伊大学Urbana-Champaign分校Frederick Seitz材料研究实验室的资深研究员Julio Soares博士表示:“实验室当时购买了WITec的第一套NSOM设备,我们很荣幸成为WITec进一步发展的基石并得以载入WITec公司史册。在我看来,几乎不需要任何技术支持但设备还在持续运转,这本身就是一项很大的成就。

WITec研发总监Olaf Hollricher博士说:“回顾整个拉曼成像历史,WITec的创新和发展让我记忆犹新。过去20年我们带来了巨大的拉曼分析的技术优势,而这些发展惠及从半导体到纺织纤维再到癌细胞等众多材料分析领域。我们一直在推进拉曼成像技术新概念的研发,而我们所获的众多奖项就是对这些研发产品的认可。”

成立之初,WITec拉曼显微镜就能实现快速成像,积分时间在每像素毫秒级别。追溯到90年代末,积分时间曾经是1分钟每个像素,由此WITec客户能够以超乎寻常的速度进行测量。所有WITec拉曼成像系统都可以通过样品的光谱信息生成图像,从而识别样品的化学成份结构。WITec也是第一家将多种显微技术融合到一台设备里的公司,WITec 拉曼-扫描电镜(RISE)联用系统就是这一技术的创新产品,这个系统在当下扫描电镜领域备受瞩目。

WITec总裁Joachim Koenen博士说:“WITec过去20年取得的成就令人欣慰。我们自主研发了许多全新的引以为豪的拉曼成像系统和技术,也很高兴这么多年来能就此跟科学界和工业界的客户分享交流。未来还有很多有待开发和应用的拉曼成像技术理念,我和WITec团队热切地期望继续与我们的客户精诚合作。”

TrueSurface – The Original Topographic Raman Imaging System, Redefined

Innovations in Profilometer-guided Raman Imaging

 

WITec, the inventor of topographic Raman imaging, has presented at Pittcon 2017 in Chicago the next generation of its patented TrueSurface optical profilometer. The combination of surface analysis and Raman spectral acquisition enables topographic Raman imaging on rough and uneven samples. One-pass simultaneous operation makes 3D Raman chemical characterization easier and faster than ever before.

We have documented the TrueSurface in a video.

 

“WITec established Raman topographic imaging with TrueSurface. We then continued to innovate, leveraging the inherent strengths of our systems,” says Dr. Olaf Hollricher, Managing Director of R&D at WITec. “The overwhelmingly positive feedback from our customers confirms that chemical 3D surface analysis with TrueSurface is a successful concept with an enthusiastic following in academia and industry.”

With the TrueSurface option, Raman spectra are acquired from precisely along a surface, or at a set, user-defined distance from a surface. This makes the distribution of chemical components within the sample visible in three dimensions. Rough, inclined or irregularly-shaped samples can be investigated with the same ease as standard samples. The requirements of sample preparation can therefore be drastically reduced. 

As the TrueSurface sensor actively monitors and maintains a set distance between the objective and sample surface, its closed-loop operation can compensate for any variations during measurements with long integration times. This keeps the measurement area in focus at all times and produces sharp chemical Raman images with sub-micrometer resolution.

Investigations on pharmaceutical tablet coatings, geological samples, composite emulsions, complex semiconductor structures and many other applications can benefit from the ease of use, accelerated workflow and methodological advantages provided by the new TrueSurface.

“TrueSurface is for everybody who wants to just take a sample, as it is, and put it under a microscope for chemical analysis,” explains Dr. Joachim Koenen, Managing Director at WITec. "Also, the combination of confocal Raman imaging and optical profilometry provides additional information on the chemical distribution of the sample components that are of great benefit to our customers."

Oldest fossils detected by Raman imaging

When did life on Earth begin? Based on new Raman data from microfossils, scientists have dated the origin of life to at least 3,77 billion years ago.

Bubbling submarine-hydrothermal vents are believed to be the places where life on Earth emerged. Whether that happened 3.5 or 3.7 billion years ago or even further into the past is subject of intense discussion in the scientific community. Why? Because it is hard to determine whether or not chemical traces in very old sedimentary rocks– so called microfossils – are metamorphosed products of biological organisms. Dominic Papineau, a geologist who has long followed the tracks of early life, and PhD student Matthew Dodd, both from University College London (UK), along with colleagues used a microscopic approach to look for the answer. With optical microscopy they imaged thin sections from fragments found in the Nuvvuagittuq Supracrustal Belt (NSB) in Canada that once belonged to a very early oceanic crust. They identified 50 – 200 μm rosette-like structures.

Through chemical imaging performed with a WITec alpha300R confocal Raman microscope, the scientists could identify the compounds – calcite, haematite, quartz, magnetite and apatite - therein and their spatial distribution. Modern iron-oxidizing bacteria living in hot vents can form Fe-containing filaments and tubes. For that reason scientists believe that similar structures in much older rocks indicated biogenic origin. Similar structures found in Løkken jasper in Norway that geologically is somewhat younger than the NSB had already been attributed to mineralized bacteria. So the authors of the current study suggested that the carbonate rosettes they had seen are also of biogenic origin. They concluded: “Preservation in the NSV of carbonaceous material and minerals in diagenetic rosettes and granules that formed from the oxidation of biomass, together with the presence of tubes similar in mineralogy and morphology to those in younger jaspers interpreted as microfossils, reveal that life established a habitat near submarine-hydrothermal vents before 3,770 Myr ago and possibly as early as 4,290 Myr ago”.

 

In an email, Dominic Papineau wrote: “We used the WITec micro-Raman to map, down to sub-micron scales, the minerals associated with the oldest microfossils on Earth. This was vital to the discovery of key structures like rosettes, granules as well as minerals associated with the filamentous microfossils such as micron-size apatite, carbonate, and graphitic carbon, all of which point to the metamorphosed mineralised product of decayed microbial organic matter.”

A novel and intuitive operating concept revolutionizes Raman imaging

A new software wizard guides the user through the complete investigation, from initial settings and acquisition through data and image post-processing.

Advanced functionality, accelerated workflow and enhanced hardware control

WITec, manufacturer of Raman and scanning-probe microscopes, presents a new operating concept with the powerful and intuitive Suite FIVE at Pittcon 2017. Sophisticated features and hands-on control transform the user experience, enabling the researcher to move from setup to results with unprecedented ease. Suite FIVE provides an integrated tool for data acquisition, evaluation and post-processing that enables researchers to quickly extract key information from their experiments. All Raman, AFM, SNOM and WITec correlative microscopy measurement modes are supported.

“Suite FIVE combines new functionality with a simplified operating concept that encompasses both software and hardware. The greater automation and intuitive interface speed up the process and improves the results of data acquisition and analysis. It’s altogether more accessible and powerful,” says Dr. Joachim Koenen, Managing Director at WITec.

 

 

Suite FIVE introduces several features for enhanced performance and usability:

A new software wizard guides the user through the complete investigation, from initial settings and acquisition through data and image post-processing. Presets and highlighted analytical paths accelerate the generation of high-quality images.

TrueComponent Analysis is a unique post-processing function for confocal Raman imaging measurements that automatically establishes the number of components in a sample, locates them in the image, and differentiates their individual spectra. This delivers meaningful, comprehensive information with one operation.

Hardware control from within the software has also been strengthened. The new handheld multifunction controller EasyLink provides a tactile and intuitive interface for directing the motorized stages, white light illumination, laser power, autofocus, cantilever positioning and objective selection with the new automated turret. This further integration of WITec’s hardware and software provides greater synergy and speed while transforming the user experience.

“TrueComponent Analysis is the standout technical achievement, without peer in the industry, though all the new features contribute to a transformed user experience. These are results-oriented developments with benefits that will be immediately apparent to the researcher,” says Dr. Olaf Hollricher, Managing Director of R&D at WITec.

WITec Suite FIVE will be presented at Pittcon 2017 Conference & Expo at McCormick Place in Chicago, Illinois from March 5th to the 9th. See all the new WITec developments at booth #1638.
