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.
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.
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.
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.
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
Volatile organic compounds (VOCs) are a series of compounds with boiling points from 50 to 250 degrees centigrade and are widely used as industrial chemicals/ solvents. Low concentrations of VOCs can have a significant impact on human health, as many are regarded as highly toxic, refractory and carcinogenic. The detection and determination of VOCs in the environment is of the upmost importance for both human and environmental health.
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.
Cisplatin, carboplatin, and oxaliplatin are the most widely used of platinum-based cancer chemotherapy drugs in the Western world. Cisplatin's effectiveness is due to its ability to bind to the DNA, resulting in DNA-platinum (Pt) adducts, which bend the DNA. The cells must then repair the DNA damage, otherwise DNA replication is blocked resulting in cell death. Many cancers are initially sensitive to platinum-based treatment, but patients frequently relapse with tumors displaying resistance to further cisplatin therapy.
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.
Mycotoxins produced by fungi as toxic secondary metabolites, leave grains, maize and cereals particularly vulnerable. With this in mind, and considering that an estimated 25% of all crops show some signs of mycotoxin contamination, many countries have established regulatory guidelines for maximum mycotoxin limits in not only feed and grain, but also in processed food products.
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.
