    Which 96-Well Plate Should I Use for LCMS?
    Tue, Oct 6, 2020 0 Which 96-Well Plate Should I Use for LCMS?
    The decision of which 96-well plate you should use depends on the characteristics of your plate as well as the sample that you are analyzing. Some customers prefer a thermal heat seal vs adhesive films so a rimmed plate is needed. Other customers are concerned with sample recovery, if they need to get the last few µLs of precious sample. One final concern is sample-binding to the plastic plates.

    Pesticide and Mycotoxin Analysis in Cannabis Brownies
    Tue, Jul 14, 2020 0 Pesticide and Mycotoxin Analysis in Cannabis Brownies

    Reliable and accurate results for pesticide and mycotoxin testing is of utmost importance for the safety of people consuming cannabis-derived products such as cannabis brownies and other edibles. Edibles are one of the most popular categories of consumption of cannabis-based products, and brownies are one of the most commonly consumed edible. Brownies contain high levels of potential interferences (carbohydrates and fats), so methods developed for this application will be a great starting point for similar matrices.

    Minimizing Touch Points Involved with Gas Usage in the Laboratory
    Wed, Jun 17, 2020 0 Minimizing Touch Points Involved with Gas Usage in the Laboratory

    The COVID-19 pandemic has affected laboratories in many ways, including many cutting the number of employees in the laboratory at any given time. Spreading the virus is a main concern across workplaces, and eliminating unnecessary touch points between employees is more important now than it has ever been. An inhouse stand alone gas generator reduces the number of personnel contact involved with the use of gas bottles and cylinders in the laboratory. Once a generator is installed in the laboratory, minimum user interaction is required for 24/7 usage, and minimal maintenance is required.

    Whether analyzing for drugs, forensic evidence, or specific compounds in a specific clinical matrix, accurate sample analysis is important. For example, as the American Chemical Society discusses, “The credibility of the legal system critically depends on forensic tests that are consistent, accurate, and scientifically valid.” If a sample is analyzed inaccurately, serious consequences may occur so it is important that precautions are taken to eliminate margins of error in every step of the analysis.

    Quantitatively Determining 15 Endogenous Steroids in Human Serum

    As women and men age, many face issues that can be treated by hormone replacement therapy, according to the Women’s Healthcare Associates. However, hormone steroids are metabolized differently from person to person, which leads to complexity in treating a patient effectively without increasing a person’s risk for diseases such as cancer, dementia, and loss of bone density. It is important for researchers to be able to quantitatively determine endogenous steroid levels in order to monitor patient health and success with the hormone replacement therapies.
