Product news

Developer of chemistry software for the pharmaceutical and chemical industries, Advanced Chemistry Development, Inc., (ACD/Labs) is now offering a 30-day free trial of ACD/MS Fragmenter—a useful tool for predicting MS fragmentation of small organic molecules.

ACD/MS Fragmenter makes it easy to review possible fragment ion structures, taking into account the type of ionization and the polarity of the molecule, then automatically applying standard fragmentation rules. The results are clearly displayed in a fragmentation tree. Pathways of interest can be isolated for closer analysis, or used for reports and presentations with just a few mouse clicks.
The latest version of ACD/MS Fragmenter also includes the ability to predict fragmentation for negative ionization experiments, making it possible to use ACD/MS Fragmenter on a wider range of chemical compounds.

The free 30-day trial offered on the ACD/Labs website will allow mass spectrometrists to evaluate the capabilities of ACD/MS Fragmenter using virtually any small organic molecule drawn or imported into ACD/ChemSketch. In addition to saving time and effort, the software’s use of accepted fragmentation rules derived from the literature eliminates intangible problems such as inexperience or bias that may get in the way when examining unusual, but possible, fragmentation pathways.

ACD/MS Fragmenter shows all predicted fragment ion structures, which complements the spectrum assignment capabilities of ACD/MS Processor to give you a better understanding of the relationship between the structure and spectrum of your molecule. Simply attach a structure to your experimental spectrum and automatically assign fragments to peaks. Verify that the structure matches the spectrum, or compare several structures to find the best match.

Visit our website today to learn more and to download the 30-day free trial of ACD/MS Fragmenter.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.Chem / BioinformaticsCheminformatics and bioinformatics are computational techniques used in chemistry and biology, respectively, for data acquisition, processing and storage. Cheminformatics focuses on compound information, whereas bioinformatics is mainly applied to analysis and modeling of genomics, genetic and sequencing information. Hardware and software is available for data acquisition, analysis, management and storage.Molecular Recognition SoftwareMolecular recognition software is widely used to analyze DNA, RNA, proteins and chemicals. The software can be useful for graphical viewing, comparative analyses, high-throughput screening, genomics, proteomics and phylogenetics. Molecular recognition software uses bioinformatics tools and analyses such as BLAST searches and generates structural predictions, 3D structures and sequencing information.
