OPUS: Latest Release

• New Graphical User Interface (GUI): The GUI is modernized with ribbons as it is well-known from Microsoft Office.
  Getting started with OPUS is made easier for new users because the GUI follows the philosophy of Microsoft Office.
  Customers who have worked with the previous user interface will quickly find their way around because the icons are unchanged.
  BRUKER Optics has taken the opportunity to review the allocation of all functions, grouped them and assigned some to more suitable menus.
  The HOME menu gives the user quick access to all essential and frequently used functions. As usual, the views differ depending on the selected workspace.

New Graphical Method Editor in the Rapid Scan Time Resolved Measurement Dialog: The “Method Editor” tab of the “Rapid Scan Time Resolved Measurement” dialog has been extended by a graphical representation of the TRS-method. The method is shown as a sequence of graphical blocks, each block standing for a command/line in the method.
Blocks can be inserted into the method, moved to another position or deleted, by mouse-drag and drop. Command parameters are entered or edited via specific user controls on each block. The familiar text representation is still available.

• Autonomous Composition Identifier Software: Composition-AID: Chemical composition identification of samples based on their IR or Raman spectral data. A multi-step artificial intelligence algorithm determines the best match for the query spectrum using reference spectral databases.
  The algorithm automatically evaluates results for pure substances as well as complex mixtures without requiring any input from the user. For the recommended and possible alternative results, a composite from the weighted component spectra and its difference to the sample spectrum is calculated.

Highlights of Composition-AID:

• Best match recommendation for optimal balance of reliability and sensitivity
• Extensive hit quality diagnostics:
  o    difference spectrum between composite and query spectrum (=residual)
  o    graph of hit quality and unexplained peaks plotted against component number
• High performance – comprehensive multi-component analysis in seconds
• Interactive report generation of single and multiple alternative results
  

• Particle Identification: It combines capabilities of OPUS functions “Find Particles” and “Cluster ID” to ease the workflow for detection and identification of particles from IR and Raman images. The new function allows to detect particles in IR and Raman chemical images and determine their dimensions and identity in a single evaluation step.

• Particle Statistics: The tool is for examining results from IR and Raman particle analysis by filtering and graphically displaying the data according to attributes like dimension, identity and hit quality.

• Microplastic Classification: The microplastic classification function is a machine-learning based classifier that determines the identity and dimensions of microplastics particles that have been measured by FT-IR imaging (i.e. with LUMOS II-IMG). The classifier has been trained on reference data which has been recorded on aluminum oxide (“Anodisc”) filters.

• Anodisc surface model: The visual quality of microscopic overview images is optimized for uneven aluminum oxide (“Anodisc”) filter surfaces. The surfaces of Anodisc filters, which are a commonly used substrate in microplastics analysis can show some unevenness of the surface. The “Anodisc surface model” function determines this variation in the filter topology and generates a model for focus correction during visual image generation, resulting of higher sharpness of the entire field of view. The improved visual image quality allows a better correlation of the visual and IR image. Furthermore, a better detection of particles based on the visual image for single point analysis is achieved.

• Flat-plane interpolation for overview images: It is used for optimization of the visual quality of microscopic overview images of tilted sample surfaces. The “Flat-plane interpolation” function determines the tilt of flat sample surfaces which are not perfectly levelled. The focus is corrected accordingly during visual image generation, resulting in a higher sharpness of the entire field of view.

• 3D Quick Compare: Evaluation of 3D spectral data by using the OPUS Quick Compare methods. IR and Raman images are generated by correlation of pixel spectra with known reference spectra. A user-defined threshold sets the minimum correlation coefficient needed for identifying or verifying the presence of the reference components.

• Co-local-measurement: Analysis of identical region of interest on microscopic samples using both Raman and IR microscopy. The “Co-local measurement” function allows to transfer the overview image and the measurement area between LUMOS II, HYPERION II and SENTERRA II. This makes the analysis of the identical region of interest possible, using both the IR and Raman technology.

New TOUCH 5.1 features include:

• Mobile-IR II Support: The recently released MOBILE-IR II is fully supported. A standby mode, temperature control of the ATR accessory, and customized home screens have been added.
  
  Dedicated help/tutorial videos can now be accessed directly from the Workflow GUI.

• Data Export: Measurement data of sample spectra can be automatically exported to various file formats after measurement. Available file formats are data point table,  JCamp, Galactic, Pirouette, XML, Matlab 4, Matlab 5, imzML
  

New dedicated Workflows:

OPUS-TOUCH 5.1 provides new dedicated Workflows that make it even easier to work with dedicated accessories or special evaluation methods.

Newly added:

• Emissivity Measurement Workflow: Allows to calculate emissivity from reflection measurements conducted with our accessories A562, A519 and A505
• Oil-in-Water Workflow: Allows the quantification and reporting of oil and grease in waste and drinking water, oil in diesel exhaust fluid, oil in anhydrous ammonia, and oil in soil according to the Standard Test Method ASTM D7575 in a guided Workflow.
• Multi-Measurement Workflow: Allows to automatically average a freely selectable number of spectra. Besides the average spectrum also a standard deviation spectrum is calculated.

• Easy Measurement: A new graphical user interface intuitively guides the users through the setup of their experiment and the measurement.

New BRAVO handheld Raman features include:

• BRAVO Web Access: A secure https interface enables to access system information, licensing functionality, EAP-TLS certificate management and a BRAVO screen sharing functionality.
• BRAVO Viewer: The secure https web access enables screen sharing of the BRAVO GUI as well as full remote control of the BRAVO software via a web browser.
• Device Diagnostics: Updated device diagnostics functionality for fast and easy access to performance status information.
