OPUS, the "all-in-one" IR and Raman spectroscopy software consists of a suite of software packages that cover both standard and specialized applications.

 

OPUS offers an extensive set of spectral processing routines such as the spectrum calculator, absorbance-to-transmission conversion, automatic baseline correction, peak picking and many more. All the functions are set-up such that multiple spectra can be manipulated at the same time. Drag & drop handling of spectral data and a variety of interactive functions make OPUS extremely easy-to-use. Interactive spectra manipulation and evaluation functions, such as peak pick, baseline correction, integration and spectral subtraction for semi-quantitative work are also part of the standard package. OPUS provides spectral processing routines that meet the demands of analytical and research laboratories as well as process control. The new version of OPUS also includes a Comprehensive FT-IR tutorial and improved help files.

 

 

Automatic atmospheric compensation

The new automatic atmospheric compensation algorithm in OPUS means that you no longer have to worry about atmospheric gases, such as water vapour and carbon dioxide, in your IR spectra. The unique algorithm built into the software automatically compensates for the water vapour and carbon dioxide features during a measurement and doesn't require any reference spectra. In addition the algorithm allows you to automatically correct
previously measured spectra.

OPUS/VALIDATION

OPUS/VALIDATION supports the demands of the 21 CFR Part 11 "Electronic Records, Electronic Signatures" regulation set by the FDA:

• Enhanced user management for OPUS with separate OPUS login and audit trail
• Electronic signatures for spectra and evaluation methods
• Audit trail for spectra evaluation methods and signatures.

 

Quick Print

For fast and easy plotting, the QuickPrint feature will print the contents of active OPUS window with a single mouse click.

 

The WYSIWYG interface within the plot layout editor allows the user to configure customized plot configurations. Frames can contain spectra, 3D-views, reports, tables, chemical structures, bitmaps and text files. Plot layouts can be saved and reloaded, and plotting can be started directly from the layout screen or from the print preview.

 

Spectral Libraries

OPUS/SEARCH is a package for identifying unknown compounds by searching against a database of known spectra. In addition to spectrum searches users can also search for chemical structures, information or individual peaks. OPUS/SEARCH can work with commercial libraries from many different sources. The built-in library editor allows users to create and maintain their own libraries. The package also includes a structure editor which can be used to draw, display and plot chemical structures and structure queries.

 

 

The OPUS™ measurement software can be completely configured to meet your needs. OPUS/LAB is an intuitive and easy to use software interface for your complete routine analysis tasks. It can be used by untrained personnel from the production line as well as by your experienced laboratory staff. OPUS/QUANT is a chemometric software package for setting up sophisticated methods quantitative analysis. OPUS/IDENT uses hierarchical libraries for the identification of samples. All OPUS™ packages can be seamlessly integrated and use the full functionality of OPUS™.

 

OPUS/IDENT is a specialized package for identification and verification of spectra using a customized library. A series of set up screens guide the user through the library building and verification process. Customized macros permit easy operation for even unskilled personnel. Cluster analysis routines allow the user to graphically verify the quality of a reference database in the form of a dendrogram.

 

The conformity test is an easy-to-use and sensitive method for checking the conformity of a product to a known reference during the production process. It is based on a simple principle: "same sample, similar NIR-spectrum", and simply checks for deviations of a measured spectrum from the expected spectrum, thereby indicating whether the product is "within spec" or "out of spec".

 

The conformity test is a two-step process. The first step involves measuring several spectra of a production sample that is known to be "within specification". An average spectrum and a standard deviation spectrum are generated. The latter defines a statistical region around the spectrum as an "acceptance region". The average spectrum then becomes a reference against which spectra are compared at various stages of production. As soon as a production sample spectrum falls within the acceptable region, it indicates "conformity" with the reference. The sensitivity of the test can be tuned by using a multiplication factor to increase or decrease the acceptance region/range.

 

Process Control

OPUS/PROCESS is a package based on the standardized OPC interface. Using this interface OPUS can be easily integrated in modern process control networks, acting as an "OPC Server" as well as an "OPC Client". The software offers an easy to use editor to allow the combination of measurement protocols and analytical methods. A data management system offers a variety of possibilities for result handling and communication with a DSC. Different protocols such as Modbus, Profibus, Industrial Ethernet or OPC are available, as well as classical data transfer by a 4-20 mA signal. Both spectral quality and instrument status are continuously monitored by OPUS/PROCESS. An alarm is generated for an instrument failure or a spectral outlier.

 

 

The OPUS/3D package generates two and three-dimensional representations of spectral data, allowing single spectra to be assembled to form contours (3D) and traces (2D). Several data post-run processing options, such as contrast-enhanced false color representations are also included. In addition all data manipulation functions can be directly applied to all 3D data

 

In combination with OPUS/CHROM, a package which links a multitude of chromatographic techniques (TGA-IR, GC-IR, HPLC-IR and TLC-IR) to OPUS, Gram-Schmidt chromatogram traces and spectral window traces can be calculated and displayed in real time.

 

OPUS/MAP and OPUS/VIDEO provide a powerful IR-imaging solution for your surface scientific problems. Using a Bruker Infrared Microscope OPUS/VIDEO can be used to obtain a real-time video image of the sample surface. IR data acquisition can be controlled directly from the video image and complete maps of the surface can be generated with a few mouse clicks. OPUS/MAP provides additional routines to completely automate the measurements.

 

Step Scan

Kinetic and modulation/demodulation experiments down to a temporal resolution of few nano-seconds can be performed with OPUS/STEP. Special measurement interfaces are available for setting up experiments with an extensive range of time resolutions, and modulation frequencies and amplitudes. OPUS/3D enhances the evaluation of the measured data. More on step scan...
