Extraction of Acidic, Neutral and Basic Drugs from Urine using ISOLUTE® HCX Columns

6 Jul 2012

Read this application note to discover a method which addresses the extraction of all three classes of drugs of abuse from urine using non-polar and cation exchange retention mechanisms on the ISOLUTE HCX mixed mode column. This protocol was optimized to eliminate the use of dichloromethane in the elution of the acidic / neutral drug fraction.

ISOLUTE SLE+ Supported Liquid Extraction Products

Biotage

ISOLUTE® SLE+ plates and columns enable efficient supported liquid extraction of analytes from whole blood, plasma, serum, urine, and oral fluid. The simple load-wait-elute method delivers 99.9% removal of proteins and phospholipids without offline steps, offering superior recovery, reproducibility, and cleaner extracts than liquid-liquid extraction.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.BiochemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.UrineThe analysis of urine is important in medicinal, anti-doping, forensic and life sciences applications. The ability to evaluate what someone has ingested through their urine enables fast detection and diagnosis of certain illnesses. Drugs of AbuseA drug of abuse is a drug that has been taken for non-medical purposes. Such drugs can have mind-altering effects, with some causing dependence and addiction.Anti-Doping ScienceAnti-doping science involves the detection of performance-enhancing drugs (PEDs) and banned substances in athletes. This field helps ensure fair competition and athlete safety. Explore anti-doping science tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.
