A fast, accurate and comprehensive LC-MS/MS method validation for the sensitive quantification of water-soluble vitamins in walnut, almond, hazelnut and pistachio fruits

First-Order Derivative Spectrophotometry for Simultaneous Determination of Vitamin C and Nicotinamide: Application in Quantitative Analysis of Cocrystals

“…Injections (1 μL) were performed at 0.3 mL·min –1 at 35 °C. The detection and quantification followed procedures described in the literature for LC-MS of water-soluble vitamins. , …”

“…The detection and quantification followed procedures described in the literature for LC-MS of water-soluble vitamins. 41,42 MS detection operation conditions used in the interface were as follows: desolvation temperature (450 °C); nebulizing gas flow (2 L•min −1 ), drying gas flow (5 L•min −1 ), and heating gas flow (7 L•min −1 ). ASC-(anionic) and NIC-(cationic) derived ions were detected at different ionization modes.…”

Effect of microwave treatment on bioactive compounds and color in tamarillo (Solanum betaceum Cav.) red variety

“…cerasiforme) respectively. As an example, a lack of vitamin B1 can cause chemical damage to the brain known as Wernicke's encephalopathy, while a lack of vitamins B6 and B12 can lead to the development of anemia [42].…”

Immunological strip sensor for the rapid determination of niacin in dietary supplements and foods

“…[11][12][13] For analysis using specialized instruments, high performance liquid chromatography (HPLC), gas chromatography (GC), liquid chromatography-mass spectrometry (L-MS), and gas chromatography-mass spectrometry (GC-MS) have been used for the detection of niacin. 14,15 Instruments using chemical analysis are well established and precise, making the results highly sensitive and reliable. However, these methodologies involve high-cost, complex equipment, well-trained personnel, and are time-consuming, making their use difficult to meet the requirements for rapid, low-cost detection.…”
