The types of exhibits analyzed using diode array UV detection include phenethylamines, cocaine, oxycodone, heroin, lysergic acid diethylamide (LSD), opium, hallucinogenic mushrooms, and \u03b3\u2010hydroxybutyrate\u2010\u03b3\u2010butyrolactone (GHB\u2010GBL). Both qualitative and quantitative analyses are achieved using run buffers that contain additives that provide for secondary equilibrium and\/or dynamic coating of the capillary. Dynamic coating of the capillary surface is accomplished by rapid flushes of 0.1\u00a0<jats:sc>N<\/jats:sc> sodium hydroxide, water, buffer containing polycation coating reagent, and a buffer containing a polyanionic coating reagent (with or without cyclodextrin(s)) or a micelle coating reagent. Dynamic coating with a polyanionic coating reagent is used for the analysis of moderately basic seized drugs and adulterants. The use of cyclodextrin in the run buffer not only allows for chiral analysis but also greatly enhances separation selectivity for achiral solutes. A capillary dynamically coated with a micelle allows for the analysis of neutral, acidic, and weakly basic drugs (GHB, GBL and neutral, acidic, and weakly basic adulterants). Dynamic coating, which gives rise to a relatively high and robust electroosmotic flow at pH &lt;\u20057, allows for rapid, precise and reproducible separations. For a wide variety of drugs, excellent linearity and migration time precision and good peak area precision (external and internal standard) is obtained. Quantitative results for synthetic mixtures are in good agreement with actual values. Screening for adulterants is greatly enhanced by the use of automated library searches.<\/jats:p>","DOI":"10.1002\/elps.200405894","type":"journal-article","created":{"date-parts":[[2004,6,2]],"date-time":"2004-06-02T05:01:22Z","timestamp":1086152482000},"page":"1580-1591","source":"Crossref","is-referenced-by-count":55,"title":["Capillary electrophoresis analysis of a wide variety of seized drugs using the same capillary with dynamic coatings"],"prefix":"10.1002","volume":"25","author":[{"given":"Ira S.","family":"Lurie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick A.","family":"Hays","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kimberly","family":"Parker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,6,2]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"23","volume-title":"The Analysis of Drugs of Abuse","author":"Huizer H.","year":"1991"},{"key":"e_1_2_1_3_2","first-page":"27","volume-title":"Gas Chromatography in Forensic Science","author":"Larsen A.
