Tensor 27 Bruker FT-IR Spectrometer

The Bruker Tensor 27 / Tensor 37 Series FT-IR Spectrometers are advanced flexible benchtop FT-IR spectrometers suitable for routine applications as well as for demanding laboratory analysis. TENSOR 27 - the basic spectrometer configuration - is designed for measurements mainly in the mid-infrared region, whereas TENSOR 37 - the advanced spectrometer configuration - allows also measurements in the near-infrared region by substituting the MIR components (source, detector, beamsplitter and sample compartment windows) for the corresponding NIR components. These optical spectrometer components can be replaced by the operator.

The TENSOR spectrometer is mainly operated by using a data system (PC workstation, notebook etc.). Setting the measurement parameters, starting the spectroscopic measurement as well as validating the spectrometer are done by means of the spectroscopy software OPUS. In addition, the Ethernet interface at the spectrometer rear side provides the possibility to operate the spectrometer also via your intranet or the internet.

The sample compartment (in case of TENSOR 27) or the sample compartment and the optical bench (in case of TENSOR 37) are purgeable. Purging the spectrometer with dry air or nitrogen gas reduces the content of unwanted atmospheric interferents (e.g. water vapor and carbon dioxide) inside the spectrometer significantly. Residual absorption by these atmospheric gases can lead to a significant high noise level and may mask in the spectrum weak spectral features of the sample. Purging is the most common method of reducing these effects of atmospheric contaminants.

The sample compartment is equipped with the QuickLock mechanism that allows for an exact and reproducible positioning and locking of various measurement accessories (provided the accessory is equipped with a QuickLock baseplate). The QuickLock mechanism enables a solid lock even for heavy and bulky accessories.

The TENSOR spectrometer is equipped with a number of features such as AAR (Automatic Accessory Recognition) ACR (Automatic Component Recognition) and Performance Guard that facilitate performing spectroscopic measurements and ensure reliable measurement results. The function AAR recognizes automatically the accessory installed in the sample compartment, performs several predefined tests and loads automatically the corresponding experiment file including the pre-defined measurement parameters. ACR recognizes automatically the currently installed optical components like source, detector and beamsplitter. These components are electronically coded so that the spectrometer firmware is able to recognize them. This information is passed on to the application software OPUS. The purpose of ACR is to enable the user to select the correct optic parameters in OPUS. In addition, the spectrometer components are monitored permanently to ensure that they operate within the specification range. This feature is called PerformanceGuard. Its purpose is to facilitate fault diagnostics.

The TENSOR spectrometer and the spectroscopy software OPUS are designed for validating the spectrometer to ensure that the spectrometer operates within the specifications and delivers reliable measurement results. For this purpose, the spectrometer is equipped with a computer-controlled internal validation unit (IVU) as a standard feature. The IVU is a wheel equipped with different filters. Depending on which test protocol (OQ1 or PQ2) is running, the corresponding filter is moved automatically in the beam path. Validation intervals and test protocols (OQ and PQ) are defined by the user using OVP3 (OPUS Validation Program).

The IR beam outlet port at right spectrometer side allows the connection of an accessory.
