  • Application Brief

    Warfarin Analysis Using a Quasar AQ UHPLC Column

    Today, Warfarin is the most widely used anticoagulant in the world, used to thin the blood and prevent clots.1 It was discovered by chance when in the 1920’s cattle in the US were found to be bleeding to death having eaten mouldy hay from sweet clover crops.2 However, the exact identity of the substance causing the haemorrhaging was to remain unknown for many years. Over the coming years studies of the spoiled hay eventually led to the extraction of a compound which was later named dicoumarol. It was observed that this dicoumarol could not act as an anticoagulant on its own. It was only after it was metabolised byfungi that it exhibited anticoagulant properties. This explained why only spoiled hay caused the outbreak in the cattle. After further research, the synthesis of a more potent anticoagulant from dicoumarol, warfarin, was produced. Warfarin first commercial use was as a rat poison in 1948, followed by license for human use in 1953. This application brief illustrates the analysis of warfarin, Figure 1, using the Quasar AQ liquid chromatography phase.

    Residual Solvents in Pharmaceuticals by USP Chapter 467 Methodology

    The synthesis of active pharmaceutical ingredients (API) may require multiple reaction steps that produce undesirable reaction byproducts or utilize various solvents that have to be removed from the finished product. These solvents and byproducts may be measured with headspace gas chromatography for those volatile residual organic solvents according to the USP chapter 467 method. Method USP 467 classifies residual solvents into three classes according to toxicity; class 1 solvents are to be avoided unless there is strong justification, class 2 solvents are those that should be limited due to toxicity concerns.

  • Application Note

    Cannabinoid Monitoring in Dried Cannabis Flowers

    This application describes an analytical method for the chromatographic separation and quantitative monitoring of seven primary cannabinoids, including THC and THC-A, in cannabis extracts by HPLC with PDA detection. Naturally occurring cannabinoids, the main biologically active component of the cannabis plant, form a complex group of closely related compounds, of which 113 are known and 70 are well described. Of these, the primary focus has been on ?9-tetrahydrocannabinol (THC), as the primary active ingredient due to its pharmacological and toxicological characteristics, upon which strict legal limits have been enforced.

    Analysis of Aflatoxins by UHPLC

    Aflatoxin B1 is considered to be the most genotoxic of the mycotoxins, and, when ingested by cows, is converted to aflatoxin M1 which has been shown to cause liver cancer in certain animals.

    Full-Spectrum, Angle-Resolved Reflectance and Transmittance of Optical Coatings Using the LAMBDA 1050+ UV/VIS/NIR Spectrophotometer with the ARTA Accessory

    We evaluated a 3M? visible mirror film for potential use in a new curved photovoltaic module using a LAMBDA 950 spectrophotometer with an ARTA accessory. In this application, the 3M? film must transmit near-infrared photons to the underlying silicon solar cells (where they will be converted directly to electricity) while reflecting visible photons to the focus of the module where they may be absorbed by, for example a wavelength-agnostic thermal absorber used to drive a heat engine.

    TurboMatrix Thermal Desorbers for Gas Chromatography

    For laboratories analyzing everything from air quality to flavors and fragrances, thermal desorption offers a faster, easier, more cost-efficient way to prepare samples for GC or GC/MS analysis. Ideal for the trace-level measurement of volatile organic compounds (VOCs)—as well as most semi-volatile chemicals—thermal desorption lets you avoid time-consuming, manual, solvent-based sample preparation in favor of a simple, streamlined, automated approach. It also delivers the added benefits of superior throughput and enhanced sensitivity.

    Analysis of Ginsenosides in Ginseng Root with the PerkinElmer Flexar FX-15 System Equipped with a PDA Detector

    Ginseng has been used as an herbal medicine in Asia for over two thousand years for its purported various health benefits, including antioxidant, anticarcinogenic, antiinflammatory, antihypertensive and anti-diabetic. The pharmacologically active compounds behind the claims of ginseng’s efficacy are ginsenosides; their underlying mechanism of action although not entirely elucidated appears to be similar to that of steroid hormones. There are a number of ginseng species, and each has its own set of ginsenosides.

    Biodiesel Concentration Measurements Using Attenuated Total Reflectance (ATR)

    Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.
