Improving confidence in peptide identification through deep learning
The newest release of Thermo Scientific Proteome Discoverer 2.5 software provides higher confidence peptide identification, more accurate quantification and higher throughput data analysis to proteomics scientists than previous versions. The intelligent software uses deep learning facilitated by a neural network based on Prosit (part of the ProteomeTools, org project1), licensed in collaboration with MSAID GmbH, to provide a more accurate prediction of fragmentation mass spectra. The technology enables more confident results in applications such as human leukocyte antigen (HLA) or metaproteomic analysis, which require large search spaces. The new release also includes a new enrichment service that helps provide biological meaning for differential analyses and support of targeted workflows. The software features tools to help deploy Thermo Scientific SureQuant Targeted Mass Spectrometry (MS) Assay Kits and custom SureQuant IS-triggered acquisition assays in proteomics laboratories.
Supporting comprehensive, automated small molecule analysis
The release of the new Thermo Scientific Compound Discoverer 3.2 software addresses the needs of researchers using high resolution-accurate mass (HRAM) gas chromatography-mass spectrometry (GC-MS) instrumentation for small molecule analysis with a fully supported software solution for Thermo Scientific Orbitrap GC-MS systems. Users can benefit from advanced sample characterization with HRAM GC-MS data for easy identification of biomarkers and other compounds, and the ability to perform statistical analysis with the software’s statistical processing engine. Two additional software nodes support chromatographic deconvolution, peak grouping and identification by spectral library search. These new nodes provide productivity gains, through an automated method for unknown compound identification with both electron ionization (EI) and positive chemical ionization (PCI) data on the GC Orbitrap system.
Overall with Thermo Scientific Compound Discoverer 3.2 software, small-molecule researchers are supported through extensive characterization capabilities, access to multiple mass spectral fragmentation library and structural database sources. Access to the large Thermo Scientific mzCloud mass spectral fragmentation library enhances connectivity and characterization for small molecule applications to help identify compounds.
Saving time and resources through increased automation in structural identification
Small molecule researchers using the Thermo Scientific Orbitrap Exploris mass spectrometer platform for structural identification and characterization will now experience the advantages of the Thermo Scientific Xcalibur 4.4 software to automate their processes and save user time. The latest upgrade broadens the AcquireX intelligent data acquisition workflow from the Orbitrap Tribrid Mass spectrometry platform to the Thermo Scientific Orbitrap Exploris 480 and 240 mass spectrometers. The new software enables the fully automated collection of high-quality MS/MS data on components of interest in a sample, reducing manual input and the need for multiple runs.

Bringing flexible solutions for biotherapeutic research
Supporting scientists in the development of new biopharmaceuticals, the newest Thermo Scientific BioPharma Finder 4.0 software introduces an advanced solution for the characterization of both protein biotherapeutics and oligonucleotide therapeutics, providing enhanced flexibility to biopharmaceutical laboratories. Using a novel MS2 prediction algorithm, automatic identification and annotation using MS2 data, the software offers increased confidence in results with reduced operator effort. The updated Sequence Manager supports DNA and RNA and allows users to create their own oligo sequences for a new level of adaptability for a wide range of studies.
Rapid technical support for analytical scientists
The upgraded Thermo Scientific Almanac v1.4 software delivers a simple and efficient method to solve technical issues with GC-MS, liquid chromatography (LC-MS) and ion chromatography (IC)-MS instruments. Building upon the remote monitoring and alerting capabilities of previous versions of the Almanac software, the latest upgrade allows analytical scientists to share supplemental information easily and securely with the service team, eliminating the need to manually explain problems.
Visualizing mass spectral data
The qualitative analysis of mass spectral data is enhanced with the release of Thermo Scientific FreeStyle 1.7 data review application for Xcalibur software, which enables mass spectrometry users to easily visualize data in multiple formats, discover new insights and make the most informed decisions in their research. The latest version features access to Multiple Mass Defect Filtered chromatograms for a mass and mass defect range, editable isotope abundance and analytics histogram views. The new solution also offers the same familiar interface and easily accessible tools that FreeStyle users are accustomed to using.
Optimizing screening in routine analysis workflows
The high-throughput screening and quantitation of compounds is a crucial process performed in routine analyses across forensic, environmental and food safety laboratories. With the introduction of the new Thermo Scientific TraceFinder 5.1 software, scientists can simplify and optimize quantitation with improved integration of difficult peaks, delivering consistent results between users. The software features the ability to search both a Thermo Fisher library and a custom library in the same method, providing access to an increased number of compounds. Laboratory scientists and technicians also benefit from streamlined reporting, with easily customizable reports that avoid complex formatting and formulas.
