  • Pumping Ions – An Exercise in Engineering Sensitivity Into the Xevo TQ-XS Mass Spectrometer

    The challenge: Create the most sensitive mass spectrometer for quantitative analysis. That’s a tall order for any design engineering team. When given that assignment for a next-generation, tandem quadrupole mass spectrometer, our design engineers first spoke to those for whom analytical sensitivity means the most: scientists doing quantitative studies for ...

  • High Throughput LC-MS-MS Analysis of Carbendazim in Orange Juice

    Highly sensitive analytical methods are necessary to prevent contaminated produce from entering the food supply. In order to help move fresh imports through customs without delay, methods must be rapid and cost effective, in order to test imports thoroughly. LC-MS offers the highly sensitive, robust measurement needed, while ultra high performance liquid chromatography enables high speed ...

  • Analysis of Haloacetic Acids in Tap Water Using LC/MS/MS

    Haloacetic acids are produced as by-products of chlorination in the water treatment purification process. Three haloacetic acids, monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), and trichloroacetic acid (TCAA), are subject to water quality standard for drinking water with established limits (MCAA: 0.02 mg/L, DCAA: 0.04 mg/L, TCAA: 0.2 mg/L) by Japan Ministry of Health, Labour and ...

  • Tof-HRMS: Rescuing low-exposure bioanalysis applications from chemical noise

    The drug development process requires pharmacokinetic (PK) analysis to be performed as part of safety and efficacy studies in both preclinical species and human subjects. For high-sensitivity bioanalysis, liquid chromatography (LC) coupled to a triple quadrupole mass spectrometer (LC-MS/MS) is considered the gold standard for quantification. However, for some low-exposure applications, ...

  • Heterogeneous electro-Fenton oxidation of azo dye methyl orange catalyzed by magnetic Fe3O4 nanoparticles

    Azo dye methyl orange (MO) degradation by heterogeneous electro-Fenton (EF) with a magnetic nano-Fe3O4 catalyst was investigated. In this study, Fe3O4 was synthesized by a coprecipitation method and characterized by X-ray diffraction and scanning electron microscopy. The influences of the main operating parameters such as current density, pH, catalyst dosage and ...

  • Has Your Dinner Menu Been Quantified?

    For decades, food security was viewed exclusively through the lens of shortages. In the 1960s, when daily food availability in emerging countries was just 1,850 kcal per person as many as half of the world’s population was malnourished. It’s easy to understand our narrow focus on increasing food production. The challenges we face have shifted. The development and ...
