Penetration of Carcinogen Across Porcine Esophagus and Applications of Disposable Pipette Extraction for Forensic Toxicology and Food Safety by Gas and Liquid Chromatography/Mass Spectrometry
… urine has become important. A rapid solid phase extraction method using disposable pipette extraction (DPX) was developed. Using DPX with LC/MS/MS and GC/MS methods, high recoveries were found in the range from 71-99 %. LODs were less than 10 ppb for all BZDs (%RSD < 10%).</p> <p>The screening …

Applications of Disposable Pipette Extraction for Analysis of Drugs of Abuse Vitamin D Metabolism Testosterone and Inborn Errors of Metabolism by Gas and Liquid Chromatography/mass Spectrometry
<p>To find a simple extraction procedure with high extraction efficiency for urinary organic acids with wide pKa range and polarity, two major ion exchange phases of weak cation and anion were experimented. For weak anion exchange, oxalic acid was found to irreversibly bind to the sorbent and small …
