Simultaneous Analysis of Remdesivir and Metabolites in Human Plasma

Remdesivir (brand name: Veklury®), which was developed by Gilead Science (U.S.) for treatment of Ebola virus disease, is a prodrug having antiviral activity against single-strand RNA viruses. It is known to be partly metabolized to activated GS-441524, the main metabolite of remdesivir, in vivo1). In this article, we present the results of ...

Analysis of Mixed Polymer Sample as Microplastics using Pyrolysis GC/MS

Fine plastic particles with sizes of several μm to about 5 mm are called microplastics (MPs), and their effect on pollution and ecosystems in marine environments is a serious concern. It has been pointed out that bioaccumulation may occur by a process of adsorption of harmful substances on MPs, and ingestion of those MPs by marine organisms in ...

ASTM D 5837-15 Compliant Quantitative Analysis of Furanic Compound (Furfural) in Transformer Insulation Oil

ASTM D 5837-15 method covers the determination in electrical insulating liquids of products of the degradation of cellulosic materials such as paper, pressboard, and cotton materials typically found as insulating materials in electrical equipment. These degradation products are substituted furan derivatives, commonly referred to as furanic ...

ASTM WK74011: New Test Method for Determination of Nitrosamines in Non-potable Water by Tandem Liquid Chromatography Mass Spectrometry (LCMSMS)

Nitrosamines are a class of nitrogen containing compounds with a known occurrence in wastewater. They may also be created in deionization and are a potential contaminant in water for reuse. The World Health Organization has issued a guideline for NDMA in drinking water at 0.1 g/L. NDMA may occur in chlorinated effluents and other wastewaters at ...

Qualitative Analysis and Quantitative Analysis of Sugars in Maple Syrup by FTIR

Maple syrup includes pure maple syrup, which is made by boiling down the sap of the sugar maple tree, and low-priced products made by adding cheap corn syrup. Because the main component of pure maple syrup is sucrose and low-priced products are primarily glucose, the difference between the two can be clarified by a qualitative analysis using FTIR. ...

ISO 20980:2020 Artichokes (Atiso) - Specification and test methods

Technically a flower that hasn’t yet bloomed, the humble artichoke has had a somewhat tumultuous history. Having been around since the Roman times, it was, for many centuries, banned from female consumption because of its so-called aphrodisiac properties. These days, however, it takes a prime place on many family tables and is also at the ...

High Speed GPC Analysis by Nexer GPC System: Calculation of Molecular Weight and Quantitative Analysis of Additives

Measurement of the molecular weight distribution of polymers is one field of HPLC utilizing the size exclusion mode and has been called GPC (gel permeation chromatography) for a long time. Recent requirements for increased throughput by high speed analysis are also considered as a priority in GPC, which is an established analytical technique. In ...

Quality standards for children

Mr. Benjamin, Managing Director of Distribution N KID Group said that at present, the Vietnamese children's toy market has 70% non-branded, only 30% is branded and safe. As noted, Vietnam currently has about 20.8 million children aged 0-12. This is a potential consumer segment that businesses have not fully exploited. Thus, to see that ...

Analysis of Residual Solvents in Pharmaceuticals by Water-Insoluble Samples Using N2 Carrier (JP17 Supplement II, USP 467)

Residual solvents in pharmaceuticals are classified from Class 1 to 3 based on their potential human health risk. Since these compounds are strictly controlled, highly sensitive analysis is required. Helium (He) is generally used as the carrier gas, but analysis using an alternative carrier gas such as N2 has also been in demand recently as He ...

Analysis of Residual Solvents in Pharmaceuticals by Water-Soluble Samples Using N2 Carrier (JP17 Supplement II, USP 467)

Residual solvents in pharmaceuticals are classified from Class 1 to 3 based on their potential human health risk. Since these compounds are strictly controlled, highly sensitive analysis is required. Helium (He) is generally used as the carrier gas, but as He supply shortages have become an issue recently, analysis using an alternative carrier gas ...
