For decades, fluorescence microscopy has been an invaluable tool in life sciences research, with new variations and implementations emerging almost every year. Laser scanning microscopy, airyscanning, structured illumination, light field and light sheet microscopy are among the many methods that have been developed through the years to overcome the limitations of the original widefield microscopy setups...

Are you plagued with poor peak shapes, low sensitivities, sample carry over and/or low recoveries for challenging compounds. Several substances are able to interact with the usual inert column hardware materials such as stainless steel or titanium. The adsorption on metallic surfaces typically leads to peak tailing, loss of recovery and sample carry over. Critical substances are especially metal-coordinating compounds, such as fumonisins, sphingophospholipids or organophosphates in general....

To protect consumers and patients, the filling weight of finished goods and drugs must be checked gravimetrically. Uniformity of dosage unit measurements ensure that the mean weight meets the specified nominal package contents and is within permissible tolerances in order to avoid over- and underdosing. Average weight control prevents underfilling of prepacked goods...

The Government Chemist (GC), hosted at LGC, has published the results of a recent international ring trial on the determination of cannabidiol (CBD) - an uncontrolled cannabinoid- and controlled cannabinoids in consumer products such as food and cosmetics. Consumer CBD products have entered the UK market rapidly in a variety of forms, including food and cosmetics. CBD when used as an ingredient in food or cosmetic products must currently be free from controlled cannabinoids....

As the COVID-19 pandemic continues, the worldwide search for an effective treatment is still ongoing. Remdesivir and GS-441524 are antiviral drugs that have been examined for the treatment of COVID-19 caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). Remdesivir is a nucleotide analogue inhibitor that can inhibit the replication of animal and human coronaviruses...

A new eBook from Freeman Technology, a Micromeritics company and global leader in powder characterisation, explores the application of powder flow measurements for monitoring and optimising granulation processes. Granulation is a vital unit operation for many industries, notably the pharmaceutical sector, but endpoint detection and scale-up remain a challenge. ‘Powder Flow Testing for Granulation Processes’ focuses on the value of bulk powder characterisation...

Method of choice: The combination of size exclusion chromatography (SEC) and light scattering detection (LS) determines molecular weight, especially for higher molecular species such as aggregates or oligomers. As an additional plus sample size and topology can also be revealed. Special attention needs to be turned to the quality of SEC columns in order to provide signals unaffected by spikes. YMC’s SEC columns support LS-detection perfectly due to a high level of inertness...

BioChromato Inc. has published a report describing how their ionRocket sample preparation device, used in combination with Direct Analysis in Real Time Mass Spectrometry (DART-MS) and Kendrick Mass Defect (KMD) analysis, provides a valuable new tool for chain analysis of fluoroelastomers.
