laboratory SPE extraction of flame retardants from sediment samples

Monitoring Flame Retardants in Environmental Sediments Using SPE

1. Environmental Occurrence of Brominated Flame Retardants Brominated flame retardants (BFRs), such as polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), and tetrabromobisphenol A (TBBPA), are widely used in plastics, textiles, and electronics to reduce flammability. Due to their persistent, bioaccumulative, and toxic properties, these compounds have become ubiquitous environmental contaminants. They are often detected in sediment,

laboratory SPE extraction of PFAS contaminants from drinking water

Using SPE to Detect Perfluoroalkyl Substances in Drinking Water

Overview of PFAS Contamination Concerns Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in industrial and consumer products due to their oil- and water-repellent properties. Their extreme persistence in the environment and bioaccumulative potential have raised significant human health concerns, including links to kidney cancer, thyroid disease, and developmental issues.

laboratory SPE extraction of phenolic compounds from olive oil samples

Extraction of Phenolic Antioxidants from Olive Oil Using SPE

Importance of Phenolic Antioxidants in Olive Oil Quality Phenolic compounds are minor yet critical constituents of olive oil, contributing significantly to its oxidative stability, sensory properties (bitterness, pungency), and health-promoting effects. Key phenolics such as hydroxytyrosol, tyrosol, oleuropein, ligstroside aglycones, and oleocanthal exhibit strong antioxidant activities that protect oil from rancidity and are linked to

laboratory SPE extraction of plasticizers from food packaging samples

SPE Cleanup Protocol for Detecting Plasticizers in Food Packaging Migrants

Overview of Plasticizer Migration from Packaging Plasticizers, particularly phthalates, are widely used in polymer-based food packaging materials to enhance flexibility and durability. However, these additives are not chemically bound to the polymer matrix, allowing them to migrate from packaging into food under conditions of heat, prolonged storage, or contact with fatty foods. This migration raises

laboratory SPE extraction of pharmaceutical metabolites from wastewater

Monitoring Pharmaceutical Metabolites in Wastewater Using SPE

Sources of Pharmaceutical Metabolites in Wastewater Pharmaceutical metabolites enter wastewater through human excretion, improper disposal of unused drugs, and industrial discharge from manufacturing facilities. After administration, drugs undergo biotransformation in the liver, producing both active and inactive metabolites excreted via urine and feces. Wastewater treatment plants (WWTPs) receive these complex mixtures, but conventional treatment processes

laboratory SPE extraction of organic acids from fermented food samples

SPE Method for Determining Organic Acids in Fermented Foods

Why Organic Acids Matter in Fermented Foods Organic acids are key markers of fermentation progress and food quality. Lactic acid and acetic acid, the primary metabolites in many fermented products, influence flavor, pH stability, and shelf life. Precise quantification of these acids helps manufacturers control fermentation consistency, verify product authenticity, and meet regulatory standards. Solid-phase

laboratory extraction of plant alkaloids using MCX SPE cartridges

Extraction of Plant Alkaloids from Agricultural Samples Using MCX SPE

Why Alkaloid Monitoring Matters in Agriculture Alkaloids are nitrogen-containing organic compounds that occur naturally in many plant species. While some alkaloids have beneficial pharmacological properties, others pose serious risks to human and animal health when present in food and feed crops. Regulatory bodies such as the FDA and EFSA have established maximum residue limits (MRLs)
