Oxazepam | C15H11ClN2O2 - PubChem

A reverse-phase high-performance liquid chromatographic procedure for simultaneous analysis of eight benzodiazepines, including oxazepam, is described. The standard curve is linear to at least 8 mg/L for each drug, and the detection limit for each was 0.05-0.10 mg/L. Extraction of each drug from serum was 95-100% complete.

2014/7/14 · The liquid-based Pap test consists of collecting cervical cells from the ectocervix and placing them into a vial containing a fluid transport medium to preserve the cells [2, 3]. Two FDA approved liquid-based Pap tests are widely used for the screening and detection of cervical cancer, pre-cancerous lesions, and atypical cells [ 4 ].

Metabolite Profiles from Dried Biofluid Spots for

Abstract. The potential of dried blood, plasma and urine spots, deposited on a paper substrate, combined with reversed-phase ultra performance liquid chromatography and orthogonal acceleration time-of-flight mass spectrometry (UPLC-oaToFMS), with electrospray ionization (ESI), has been investigated for global metabolic profiling.
