laboratory SPE extraction used for pesticide testing in fruit juice

SPE Cleanup for Detection of Pesticides in Fruit Juices

Why SPE Cleanup Matters for Pesticide Detection in Fruit Juices Fruit juices are widely consumed globally, but the presence of pesticide residues poses serious health risks. Regulatory bodies enforce strict maximum residue limits (MRLs), making reliable detection methods essential. Solid-phase extraction (SPE) has become the gold standard for sample cleanup prior to chromatographic analysis. This […]

laboratory SPE extraction of urine organic acid metabolites

Using WAX SPE to Extract Organic Acid Metabolites from Urine

Clinical Importance of Organic Acid Profiling Organic acids are key intermediates in metabolic pathways, and their urinary levels serve as biomarkers for a range of inherited metabolic disorders, including methylmalonic acidemia, propionic acidemia, and maple syrup urine disease. Inborn errors of metabolism (IEMs) often lead to accumulation of specific organic acids, making urine organic acid

laboratory SPE extraction used for fish drug residue analysis

Monitoring Veterinary Drug Residues in Fish Tissue Using SPE

Monitoring Veterinary Drug Residues in Fish Tissue Using SPE Aquaculture has grown rapidly to meet global protein demand, but with it comes the critical need to monitor veterinary drug residues in fish tissue. Unregulated use of antibiotics, antiparasitics, and growth promoters can lead to residues that pose health risks, including antibiotic resistance and allergic reactions.

laboratory SPE cleanup used for polyphenol analysis in wine

SPE Strategy for Detecting Polyphenols in Wine Samples

Why Polyphenols Matter in Wine Quality Polyphenols are the backbone of wine’s sensory and health-promoting properties. They contribute to color, astringency, bitterness, and aging potential. In red wines, anthocyanins and tannins define the structure and hue, while flavonoids and phenolic acids influence antioxidant capacity. Quantifying these compounds is essential for quality control, authenticity testing, and

laboratory SPE extraction of steroid hormones from wastewater samples

Extraction of Steroid Hormones from Wastewater Using HLB SPE

Why HLB SPE is the Gold Standard for Steroid Hormone Extraction from Wastewater Steroid hormones such as estradiol and testosterone are endocrine-disrupting compounds (EDCs) that enter water bodies through sewage, agricultural runoff, and industrial discharge. Even at nanogram-per-liter concentrations, these hormones can impair reproductive health in aquatic wildlife and potentially affect human drinking water sources.

laboratory SPE extraction used to analyze flavor compounds in beverages

SPE Cleanup for Analysis of Flavor Compounds in Beverages

SPE Cleanup for Analysis of Flavor Compounds in Beverages Beverages such as fruit juices, soft drinks, wines, and spirits contain complex flavor profiles that require precise analytical methods. Solid-phase extraction (SPE) is a critical technique for isolating and quantifying volatile and non-volatile flavor compounds before instrumental analysis. This blog outlines a robust SPE workflow for

laboratory extraction of artificial sweeteners from bottled water using SPE

Detecting Artificial Sweeteners in Bottled Water with HLB SPE

Introduction Artificial sweeteners such as sucralose and saccharin are widely used in food and beverages, but their persistence in the environment has raised concerns about potential contamination of water sources. Bottled water, often perceived as pure, can sometimes contain trace levels of these compounds due to contamination from manufacturing processes, leaching from packaging, or source

laboratory SPE extraction of alkaloids from herbal medicine samples

Extraction of Alkaloids from Traditional Chinese Medicine Using MCX SPE

The Challenge of Herbal Matrices Traditional Chinese Medicine (TCM) preparations are among the most analytically demanding samples due to their complex phytochemical composition. A single herbal decoction may contain thousands of compounds spanning a broad polarity range and diverse functional groups. For targeted analysis of alkaloids—the nitrogen-containing, often pharmacologically active bases—the analyst must contend with

laboratory SPE cleanup used for antibiotic testing in honey samples

SPE Cleanup Strategy for Detecting Antibiotics in Honey

Introduction to Antibiotic Contamination in Apiculture Antibiotics are widely used in apiculture to combat bacterial diseases such as American foulbrood and European foulbrood. However, their misuse or overuse can lead to residue accumulation in honey, posing risks to consumer health and international trade. Regulatory bodies like the European Union and the U.S. FDA have established
