Pesticides can adversely affect human health through the food we consume but can also leach into soil and groundwater and impact us through the environment. To keep up with a complex and constantly changing regulatory environment, your pesticide analysis solution needs to keep up with your burgeoning sample load.
Wallpaper is widely used throughout the world as an interior design choice that offers bright colors, rich designs and durability, all at an affordable price. Vinyl wallpaper has emerged as an especially durable choice over paper and non-woven varieties of wallpaper, however, its manufacturing poses many environmental concerns. When manufacturing wallpaper, a large amount of organic solvent is utilized in the treatment and printing processes. As a result, high levels of volatile organic compounds (VOCs) can be present in the product, which pose an inhalation risk to humans. To identify potential levels of VOCs in wallpaper samples, a method was undertaken, targeting 35 volatile organic compounds using a PerkinElmer TurboMatrix™ 650 ATD and PerkinElmer Clarus® SQ8 GC/MS, with results and methodology introduced in this study.
Chlorophenols are by-products of the drinking water purification process and are also widely used as wood preservatives, herbicides and pesticides. In this study, the derivatization and extraction happened in the headspace vials during the vial thermostatting step. The derivatization reaction is affected by temperature and time, therefore the thermostat time and oven temperature of the headspace sampler were investigated for optimum derivitization/extraction conditions.
Liquid chromatography-tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide The state of Oregon has issued regulatory limits for 59 pesticide residues in both cannabis flower and concentrates, while other states have come up with
Measuring the amount of metals in CNTs presents a challenge. High levels can be measured directly in the solid by several techniques, including XRF and TEM, while low-level analysis requires complete digestion of the sample prior to analysis by ICP-OES or ICP-MS.
This work investigated the transfer of Ag and CuO nanoparticles from consumer products via simulated dermal contact by using textile wipes as a surrogate using PerkinElmer’s NexION ICP-MS single particle analyzer with the unique Syngistix Nano Application software module for data collection and analysis
In this work, we demonstrate that PerkinElmer's NexION® 2000 ICP-MS, with its unique RF generator and ion optics, coupled with the Syngistix™ Nano Application Software Module, can be used to accurately measure and characterize NP sizes of 10 nm and smaller, both alone and in a mixture of NPs of various sizes.
In this application, we describe a technique for the monitoring of six cannabinoids, including THC and CBD, in hemp seed oil by HPLC with PDA detection. Figure 1 shows the chemical structures for the six cannabinoids. In recent years, scientific knowledge regarding the composition and health benefits of edible hemp products has significantly increased. Hemp seed oil has been promoted as a good source of nutritious omega-6 and omega-3 polyunsaturated acids, and may be a cleaner, more sustainable alternative to fish oil.
Nanoparticles (NPs) have been of significant interest over the last two decades as they offer attractive benefits for drug delivery to overcome limitations in conventional chemotherapy. Nanoparticles can be engineered to carry both drugs and imaging probes to simultaneously detect and treat cancer. They may also be designed to specifically target diseased tissues and cells in the body. A number of nanoparticlebased cancer therapeutics have been approved for clinical use and/or are currently under development.
In the textile industry, the use of titanium dioxide (TiO2) nanoparticles (NPs) is increasing due to their ability to provide UV protection, increase the hydrophilic nature of fabrics, provide antibacterial characteristics, and reduce odors. This work studies the release of TiO2 NPs from various commercial textile products which do not advertise that TiO2 NPs have been added.
Customer complaints of odors within a new car are rising with the increasing number of new car buyers. Although odors can be subjective, it is now well known that the new car smell is the result of chemicals emitted from the in-vehicle interior components such as the dashboard, interior panels, seat coverings, flooring materials, and so on. This application note describes a method for the automotive industry that provides a qualitative analysis and the olfactory character of each component using the TD-GC/MS-Olfactory Port.
