A new application note describes an optimized method for pesticide analysis by GC/MS/MS using hydrogen carrier gas while maintaining sensitivity to meet maximum residue limits. The presented method allowed for accurate quantitation of 92% and 93% of target pesticides at or below 10 ppb in spinach with hydrogen when using the Agilent 8890/7000E and the 8890/7010C GC/TQ systems, respectively. These results were compared to quantitation of 98.5% with helium when using the Agilent 8890/7000E GC/TQ system. Simultaneous dynamic MRM and full scan data acquisition mode was demonstrated for accurate quantitation and reliable compound identification based on spectral matching.

Have you ever used liquid pesticides? 🌿 In order to get the most out of the product, it is important that small drops of the product remain on the leaves when spraying and wet them well. 💦 Interfacial chemical measuring instruments help optimize the composition of the pesticides: - Tensiometers measure the value of surface tension and critical micelle concentration (CMC) (= efficiency assessment) - Bubble pressure tensiometers measure dynamic surface tension - Drop shape analysis determines the contact angle ➡️ Learn more in our use case: https://bit.ly/3TiJltt #KRUSS #surfacescience #scienceandtechnology #wetting #pesticides

An agency tasked with patrolling federal roads in #Brazil has reported a surge in volumes of #illegal #pesticides seized from criminals in the last eight years, including a record 358 metric tons apprehended in 2022 when the country harvested close to 300 million tons of grains. According to information sent to Reuters by the federal highway police (PRF), #herbicide Paraquat, banned in 2021, and #insecticides Thiamethoxam and Emamectin Benzoate are among #chemicals most commonly seized by authorities.

🌿 As an agrochemical professional, DFR (Dislodgeable Foliar Residue) analysis is a crucial step in assessing pesticide safety. This method determines the amount of active ingredient residue present on crop leaves, and therefore the amount likely to end up on workers' skin or clothing.   🔬🍃This process requires great methodological rigor, both in the field when taking samples and during the "dislodging" part in the laboratory. Dislodging involves extracting residues from leaves using a washing solution, in order to assess the real risk to farmers, pickers and other exposed workers.   👨🔬En as an expert in the agrochemical field, #Redebel is proud to contribute to making pesticide use safer by conducting LLW trials in a professional and conscientious manner. The reliability of this data is essential to guarantee worker safety and product compliance for registration.   #DFR #Safety #Agrochemistry #Pesticides #RiskAssessment

Some key take aways from our event last week? 👇     How very important sampling is. How measurement uncertainty must be taken into account. How complex the detection of pesticides can be.   Speaking of which.. ❓What if a pesticide, let’s say, #biphenyl – is detected on your sample, but you are sure and confident it has not been used. How to explain this result?   ❗What if we tell you that biphenyl’s chemical structure is strikingly similar to polychlorinated biphenyls (#PCB's).. Could the result actually be due to contamination with dioxins and PCB's during the drying process of your sample? 🤔   To learn more on this or other unexpected sources of pesticides, read our white paper!   📄 👉https://lnkd.in/e2CrmJN9   #Pesticides #Contamination #QA #FoodSafety #FeedSafety #SeminarInsights #WhitePaper

🚀 Effective automation in polar pesticide analysis using Micro-SPE cartridges Efficient sample preparation is crucial for accurate and reliable analysis of polar pesticides like #glyphosate. In an application note (linked below), we have explored the capabilities of our recent µSPE cartridge to streamline this process. 🥜 In a nutshell - cartridge features ➡ Septum-Free Design: Eliminates potential contamination/leaking and pressure issues. ➡ High-Pressure Compatibility: Up to 10 bar for efficient and rapid extractions. ➡ Multiple Elution Options: Allows optimization for a wide range of analytes. ➡ High Sorbent Capacity: Up to 100 mg for greater sample clean-up. ➡ Chemical Inertness: Minimizes unwanted interactions with target compounds. 🐝 #SAX Cartridges for #Polar #Pesticide #Analysis We specifically investigated the Strong Anion Exchange (SAX) cartridge for its effectiveness in the recovery and reproducibility of glyphosate and other highly polar pesticides from complex food matrices like honey. 📄 #Application #Note For a deeper dive into the methodology and results, check out this app note https://lnkd.in/ebCTyrdx 👍 Do you want to try our SAX PAL System Cartridge?
