布鲁克发布Vertex FM 中远红外一气呵成
中远红外光谱一气呵成 – 傅立叶红外光谱界多年的梦想终得实现
2014年十月于德国埃特林根，布鲁克集团光学事业部全球同步首发可以一次测试覆盖中红外、远红外和太赫兹光谱范围的傅立叶红外谱仪超宽谱区最新应用技术。继不久前问世的超宽谱区中远红外分束器后，布鲁克又推出了全新的超宽谱区中远红外DTGS检测器。VERTEX 70吹扫型和VERTEX 70v真空型研究级傅立叶红外光谱仪配置这两个新型超宽波段的红外光学部件，促成了VERTEX FM中远红外波段无与伦比的优势：您无需切换分束器或检测器、无需后续拼接谱图，只需一次测量，即可获得一张6,000 cm-1至50 cm-1的完整中远红外光谱。
傅立叶红外光谱仪的光谱范围取决于其所配备的光源、分束器和检测器的综合光学响应范围。中红外标准谱区，由于主要受限于可供选用的分束器的材质，通常截止于350 cm-1 (KBr分束器) 或者200 cm-1 (CsI分束器)。如果想扩展光谱范围至远红外和太赫兹区，通常需要一次甚至多次更换远红外分束器和检测器。而每次更换时，使用者都需手动打开谱仪光学腔。布鲁克最新推出的VERTEX FM功能，结合了新型超宽谱区中远红外分束器、中远红外检测器和标配红外光源，可以单次测量覆盖6,000 cm-1到50 cm-1的完整中远红外谱区，并广泛适用于透射、反射和衰减全反射等测量模式。独一无二的VERTEX FM技术是继几年前布鲁克VERTEX 80v高端研究级真空光谱仪的全自动分束器转换器和全自动检测器切换（多达五个检测器）功能后，布鲁克针对VERTEX 70(v)系列光谱仪的又一创新之举。
VERTEX 70v真空型光谱仪配置了VERTEX FM功能后，可以结合外接水冷高压汞灯，将远红外/太赫兹谱区进一步延伸至10 cm-1。
从中红外至远红外的谱区扩展，即突破传统中红外400 cm-1的界限，对很多分子振动光谱的应用领域有着至关重要的意义。这些应用领域包括无机和有机金属的化学分析、地质学和医药业，以及各种物理应用，如对多晶型物的筛分、对结晶度的检测和低温基质隔离光谱学。图中所示的是用VERTEX FM功能单次测量所得的维生素C的中远红外ATR光谱图。该谱证明，使用VERTEX 70或VERTEX 70v，并配置VERTEX FM新功能，您可以轻松快捷的获得从4,000 cm-1到50 cm-1的中远红外光谱区域的样品信息。

VERTEX FM: Far and Mid IR Spectroscopy in One Step -An FT-IR Dream Becomes a Reality
Ettlingen, Germany, October, 2014 – Bruker Corporation announces the world’s first FT-IR spectrometer which covers the complete mid and far Infrared/THz spectral ranges in one step with no gaps! In addition to the recently introduced wide range MIR-FIR beamsplitter for the VERTEX 70 series research FT-IR spectrometers now Bruker offers a new wide range MIR-FIR DLaTGS detector. Both together are the basis of the unique VERTEX FM FIR-MIR extension for the VERTEX 70 purge and VERTEX 70v vacuum systems which provide data collection from 6000 cm-1 down to 50 cm-1 in one step without the need of any beamsplitter or detector exchange.
The achievable spectral range of an FT-IR spectrometer is defined by the intersection of the efficiency ranges of the used source, beamsplitter, and detector. The lower limit of the spectral range is very dependent upon the beamsplitter, and is typically limited to 350 cm-1 (KBr) or 200 cm-1 (CsI). To extend the spectral range further into the far IR and THz spectral ranges one or more additional far IR beamsplitters and detectors are required and because of this the user has to manually open the access flap of the spectrometer optics bench. Now available for the first time is Bruker’s VERTEX FM feature which combines the unique wide spectral range beamsplitter, the new wide range detector and the standard IR source to cover the spectral range from 6000 cm-1 down to 50 cm-1 in one step for all types of transmittance, reflectance and ATR measurements. The unique VERTEX FM technology complements the automatic beamsplitter changer unit BMS-c and detector switching devices since several years available for the VERTEX 80v high end research FT-IR spectrometer.
When the VERTEX 70v vacuum spectrometer is equipped with the VERTEX FM spectroscopy option, the spectral range is extended down to 10 cm-1 utilizing the external water cooled mercury arc high power lamp and automatic source switching.
The extension of the mid IR towards the far IR spectral range below 400 cm-1 is of general interest for molecular vibrational analysis for inorganic and organometallic chemistry, for geological, pharmaceutical, and physical applications, polymorphs and crystallinity analysis as well as for matrix isolation spectroscopy. The ATR measurement of Ascorbic Acid shown here demonstrates that with the Bruker VERTEX 70 or VERTEX 70v FT-IR spectrometers, the new VERTEX FM option yields a spectral range from 4000 cm-1 to 50 cm-1 in a single very convenient data acquisition.
