布魯克發布VertexFM中遠紅外一氣呵成

　　中遠紅外光譜一氣呵成 – 傅立葉紅外光譜界多年的夢想終得實現

　　2014年十月于德國埃特林根，布魯克集團光學事業部全球同步首發可以一次測試覆蓋中紅外、遠紅外和太赫茲光譜范圍的傅立葉紅外譜儀超寬譜區最新應用技術。繼不久前問世的超寬譜區中遠紅外分束器后，布魯克又推出了全新的超寬譜區中遠紅外DTGS檢測器。VERTEX 70吹掃型和VERTEX 70v真空型研究級傅立葉紅外光譜儀配置這兩個新型超寬波段的紅外光學部件，促成了VERTEX FM中遠紅外波段無與倫比的優勢：您無需切換分束器或檢測器、無需后續拼接譜圖，只需一次測量，即可獲得一張6,000 cm^-1至50 cm^-1的完整中遠紅外光譜。

　　傅立葉紅外光譜儀的光譜范圍取決于其所配備的光源、分束器和檢測器的綜合光學響應范圍。中紅外標準譜區，由于主要受限于可供選用的分束器的材質，通常截止于350 cm^-1 (KBr分束器) 或者200 cm^-1 (CsI分束器)。如果想擴展光譜范圍至遠紅外和太赫茲區，通常需要一次甚至多次更換遠紅外分束器和檢測器。而每次更換時，使用者都需手動打開譜儀光學腔。布魯克最新推出的VERTEX FM功能，結合了新型超寬譜區中遠紅外分束器、中遠紅外檢測器和標配紅外光源，可以單次測量覆蓋6,000 cm-1到50 cm-1的完整中遠紅外譜區，并廣泛適用于透射、反射和衰減全反射等測量模式。獨一無二的VERTEX FM技術是繼幾年前布魯克VERTEX 80v高端研究級真空光譜儀的全自動分束器轉換器和全自動檢測器切換（多達五個檢測器）功能后，布魯克針對VERTEX 70(v)系列光譜儀的又一創新之舉。

　　VERTEX 70v真空型光譜儀配置了VERTEX FM功能后，可以結合外接水冷高壓汞燈，將遠紅外/太赫茲譜區進一步延伸至10 cm-1。

　　從中紅外至遠紅外的譜區擴展，即突破傳統中紅外400 cm^-1的界限，對很多分子振動光譜的應用領域有著至關重要的意義。這些應用領域包括無機和有機金屬的化學分析、地質學和醫藥業，以及各種物理應用，如對多晶型物的篩分、對結晶度的檢測和低溫基質隔離光譜學。圖中所示的是用VERTEX FM功能單次測量所得的維生素C的中遠紅外ATR光譜圖。該譜證明，使用VERTEX 70或VERTEX 70v，并配置VERTEX FM新功能，您可以輕松快捷的獲得從4,000 cm-1到50 cm-1的中遠紅外光譜區域的樣品信息。

　　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.
