  • Enhanced Purification of Capsaicins with the CombiFlash® EZ Prep

    Abstract In this application note, capsaicins are used as a model for compounds difficult to resolve with flash chromatography. Capsaicin compounds possess very similar structures making them difficult to resolve from each other. Although these compounds can be resolved on flash chromatography columns, such as the RediSep® Rf Gold C18, preparative high pressure liquid chromatography ...

  • NASA's Uses the Largest Airborne Telescope Observatory in the World

    NASA's latest project, a joint collaboration with the German Aerospace Center, breaks new ground for scientific discoveries. The new Stratospheric Observatory for Infrared Astronomy (or SOFIA, as it's known) makes use of a modified Boeing aircraft and a reflecting telescope to enable spatial observations far more detailed than anything a ...

  • How Gas Analyzers Can Benefit the Automotive Industry

    Emissions standards imposed upon auto engineering firms in the US could be set to change, as the Environmental Protection Agency reviews the current standards which have been in place since 2012. The EPA are considering redressing the greenhouse gas emissions standards for light-duty vehicles due for production in the model years 2022—2025, citing changing economic circumstances as the ...

  • What is Catalysis?

    Catalysis is the process of modifying a chemical reaction with the use of a catalyst. This process only works with chemicals that have an existing reaction, and it is used to accelerate the reaction for commercial purposes. Catalysis occurs faster than a standard chemical reaction because catalysts require less activation energy, which is the minimum level of energy necessary to initiate a ...

  • Reservoir Management - Online Oil-In-Water Monitor - Case Study

    Background Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations. New generation OiW monitors: Yield more accurate O  iW concentrations Improve accuracy of the OiW measurements, allowing operators to optimize water ...

  • In-House Oil Analysis Lab Saves Gold Mine Millions in Downtime, Repair and Replacement Costs

    A low-grade surface mining operation depends upon huge and expensive equipment such as Hitachi 5500 shovels and Caterpillar 793 haul trucks. Oil analysis is essential to identify problems so they can be corrected before they cause equipment to go down for major repairs. In the past, a multinational mining firm sent samples to an outside lab for analysis but the cost of this approach limited the ...

  • What is TPO and Why is it Performed?

    Temperature programmed oxidation (TPO) is an analytical technique capable of establishing the oxidation of an element or compound through thermal excitation, with various applications in the field of catalysis. The performance of TPO requires a furnace or microreactor capable of increasing temperatures of a catalyst in precise increments up to extreme conditions, for example in brackets of ...

  • Taking matters into hand - Case Study

    Biofuels must be up to scratch as contaminated or improperly blended fuel can damage a  company’s bottom line. To ensure product quality several options exist including laboratory analysis, field test kits and portable lab instruments.  Laboratory testing would be the ideal solution if everyone had the budget and the time to wait for the results.  But in a market where time ...
