The devices packed using the injection filling method had excellent separation efficiency attributes. Flow through and eluted protein peaks obtained using a device with an intentional minor indentation on the inner surface of the chromatography device showed pre-peaks (or fronting) and these peaks were wider than those obtained with a device without such an indentation. Surface imperfections had a greater impact on eluted peaks than on flow-through peaks.

However, due to the high vaporization temperature of the heating coil in e-cigarettes, cannabinoids could be converted into secondary cannabinoid products, potentially causing unintended psychological and harmful effects. A lab-built impinger and aerosol collection device was prepared to study the thermal transformation of cannabinoids during e-cigarette vaping, optimizing collection conditions according to variations in coil wattage, cartridge oil, and collection solvents. Thermal conversion of individual cannabidiolic acid (CBDA), cannabidiol (CBD), and Δ⁹-tetrahydrocannabinol (Δ⁹-THC) in e-cartridge liquid was performed with increasing coil power from 45 W to 105 W. Collected aerosol solution was derivatized with trimethylsilyl reagents and analyzed by gas chromatography-mass spectrometry (GC-MS) scan mode. Thermal vaping profiles of individual authentic cannabinoids were studied according to the variation of coil power of the e-cigarette. During the CBDA vaping process of the e-cigarette, most of the acidic CBDA was converted to neutral CBD through thermal decarboxylation and further degraded to produce several thermal products. Several interesting psychoactive Δ⁸-iso and Δ⁹-THC isomers, and cannabichromene (CBC) and CBD quinone (CBDQ) were observed from the vaping process of CBDA and CBD. In the case of Δ⁹-THC vaping, psychoactive hexahydrocannabinol (HHC) derivatives and cannabinol (CBN), were produced <em>via</em> thermal reduction and oxidation. These thermal products were identified by comparing retention times and mass spectra of authentic standards and interpreting their mass spectra. The amounts of most thermal products were increased with increasing coil power from 45 W to 105 W. In contrast, potentially harmful CBDQ was found to be highest amount at 45 W and decreased with increasing coil power. From the profile data and identification results, thermal transformation pathways of cannabinoids during the vaping process are proposed. This study will provide important information on the formation mechanism of thermal conversion products and basic guidance for risk assessment of <em>Cannabis</em> oil vaping by e-cigarette.</div></div>","PeriodicalId":347,"journal":{"name":"Journal of Chromatography A","volume":"1749 ","pages":"Article 465909"},"PeriodicalIF":3.8,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent advances in hybrid mass analyzers like quadrupole-time-of-flight analyzers (QTOF) have proved their potential for quantitative analysis. The objective of the present work was to perform a comprehensive analytical comparison of QqQ and QTOF performance for casein and ovalbumin quantification in wines. The performances of both analyzers were compared through the evaluation of fourteen wine samples applying isotope dilution analysis. Target proteins were determined employing <em>bottom-up</em> approach studying the resulting peptides from trypsin digestion. Results showed that QTOF analysis allowed the detection of 12, 6, and 4 more transitions than QqQ for α-casein, β-casein and ovalbumin, respectively. Instead, QqQ showed detection (LOD) and quantification limits (LOQ) 10-fold and 20-fold lower than QTOF for casein and ovalbumin, respectively. Sample analysis by QqQ revealed that 93 % of samples had detectable levels of casein and/or ovalbumin and 64 % showed higher levels than the EU limit for declaration.

To make phage therapy more widely available, scalable purification methods that can adequately remove endotoxins, proteins and host cell DNA must be implemented. This is particularly important when considering intravenous (IV) administration, since the presence of these impurities is highly controlled by regulatory agencies. This work aimed at developing a purification workflow amenable to large-scale manufacturing, centred on the use anion-exchange chromatography (AEC). Lytic phage T4 and <em>Escherichia coli</em> K12 were used as the infection agent and host, respectively. Since endotoxins and phages are negatively charged, the use of an alkaline phosphatase (AP) prior to AEC was investigated to reduce their net negative charge and allow an efficient separation during chromatography. AP was used at 20 or 200 U/mL, and different AEC ligands and stationary phases were tested. H-bond chromatography (without enzymatic treatment) was exploited as well. Final phage titres up to 1.26 × 10¹¹ PFU/mL (plaque forming units) and global recoveries up to 45.1 % were obtained. The highest removal of endotoxins (98.8 %) was obtained after treatment with 20 U/mL of AP, followed by AEC with a quaternary amine packed-bed column. Virtually all proteins and DNA were removed in all workflows. Some of the obtained phage preparations would be suitable for IV administration, regarding endotoxin content. These results demonstrate that an enzymatic treatment in combination with AEC is a promising and scalable alternative to current phage purification techniques.</div></div>","PeriodicalId":347,"journal":{"name":"Journal of Chromatography A","volume":"1749 ","pages":"Article 465890"},"PeriodicalIF":3.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
