Following the recent addition of ICP-MS supplies compatible with Thermo Fisher Scientific analysis equipment, Alpha Resources LLC has further expanded their supplies for ICP-MS analysis to include compatibility with two additional brands, Agilent Technologies®


and PerkinElmer® . In-stock


supplies include both sample cone and skimmer cone options compatible with leading models of ICP-MS analysis equipment. Agilent, PerkinElmer and Thermo Fisher are the top three OEM for the ICP-MS laboratory equipment used in many industrial sectors.


“Given the size of the ICP-MS market, we had always planned on supporting equipment from multiple manufacturers. It’s a little earlier than we had planned on launching the Agilent and PerkinElmer compatible cones, but once Alpha introduced the Thermo Fisher compatible cones, we began to receive customer questions about additional OEM options,” noted Ken Mantei, Director of Operations, at Alpha Resources.


“Fortunately, Alpha’s team had already been working for months to finalise a more expansive OEM compatible range of sample cones and skimmer cones. With our QA process complete and customer testing feedback in, we can confidently state that Alpha can provide cost-saving ICP-MS cones for Agilent or PerkinElmer equipment which is equal in durability to OEM cones with consistently reliable analytical output throughout their life. Exactly the kind of quality customers expect from Alpha.”


As with all Alpha products, the high-quality lab supplies are compatible for aftermarket use in the specified ICP-MS analysers. More information online: ilmt.co/PL/6ljX

Software Updates Provides New Functionality for NMR Spectroscopists and Mass Spectrometrists


ACD/Labs has announced the release of version 2022 software applications on the Spectrus® platform, and updates to Percepta® platform software. “Analytical data utilisation ‘beyond just-in-time’ decision making grows every year,” said Andrew Anderson, Vice President of Innovation and Informatics Strategy, ACD/Labs. “Version 2022 enhances the ability for scientists to interact with their organisation’s analytical data assets and leverage them for machine learning applications with bi-directional data and knowledge flow.”


The release of v2022 provides functionality for machine-readable structured output, which has the potential to assist stakeholders in R&D organisations with aspirations to digitalise laboratory workflows, reduce the degree of document-driven decision-making, and mitigate the risk of manual data transposition.


Key highlights in this batch release include: NMR - a new optimised non-uniform sampling (NUS) data processing algorithm and tools to help report the most accurate results; MS - introduction of tools for quantitative analysis and the ability to use the NIST MS search in spectral searching; Structure Drawing - the capability to search chemical structures and reactions in CAS SciFindern directly from ChemSketch, including the CAS Registry®; Nomenclature - expansion of language support; Name now supports chemical nomenclature in 21 languages; Property Prediction - expansion of data included in the Passive Absorption (Caco-2) and hERG inhibition modules; inclusion of the Class 4 ICH-M7 classification; and support for import of training libraries in all major file types; Decision Support - tools to help track development projects in Luminata® access experimental results; the ability to compare results between species more easily in MetaSense®.


Improved data flow and hardware/software integrations delivers broader support for processed data in CDSs and capabilities to export data in machine readable formats to support proliferation beyond the Spectrus environment (e.g., JSON and XML), as well as instrument control expansion for method development and optimisation. The assembled data and accessible knowledge with Spectrus® offers the flexibility to curate and store only necessary data.


The second version of Spectrus JS™ will include xC/UV/MS data processing and sophisticated, intuitive reporting. ACD/Labs’ industry-leading NMR predictors have been migrated for browser-based access, providing tools for automating, monitoring, and managing analytical data flows.

New White Paper Explains the Benefits of High-quality ACS-Grade Reagent Chemicals to Accelerate Pharmaceutical Development


If you work in the pharmaceutical industry, you know that high quality reagent chemicals are critically important to ensure the integrity of analytical testing for research and development purposes as well as in the manufacturing of drug formulations.


To meet these demands, the American Chemical Society (ACS) Committee on Reagent Chemicals has compiled the ‘de facto’ source of monographs for ACS-grade reagent chemicals including guidelines, specifications, and analytical procedures, which is recognised by the United States Pharmacopeia in its USP-NF book of compendial standards. For the very first time since its publication, ACS Reagent Chemicals is now available online in a seamless, searchable data base, which means it can be accessed by anyone, anytime, anywhere in the world.


If you are a producer of pharmaceuticals, learn how this invaluable resource can benefit your organisation including: strategies to maintain compliance with regulatory agencies; tips to expedite pharmaceutical development; purity specifications for over 500 ACS reagent chemicals; updated analytical testing procedures; a case study on replacing the sulphide precipitation test for heavy metals with plasma spectrochemistry; guidelines for implementing meaningful validation protocols.
