An SPE unit based on a commercially available, low dead\u2010volume 10 port high\u2010pressure column selector gives the possibility of trapping compounds on nine individual SPEs that have standard fittings. This allows the operator to employ specific stationary phases that are not available as SPEs in commercially available LC\u2010SPE\u2010NMR systems. Multiple trappings of small compounds like monuron, 1\u2010(4\u2010chlorophenyl)\u20103\u2010methylurea, and 4\u2010chlorophenylurea were easily performed employing a porous\u2010carbon SPE material. The system was optimized to elute the SPE\u2010trapped compounds to the NMR probes in as small a volume as possible using back\u2010flushing. The proper match of NMR probe volume and SPE column inner diameter and elution volume was discussed, as well as the necessity of drying loaded SPEs prior to NMR transfer when using porous\u2010carbon SPE material.<\/jats:p>","DOI":"10.1002\/jssc.200600238","type":"journal-article","created":{"date-parts":[[2007,2,2]],"date-time":"2007-02-02T13:58:11Z","timestamp":1170424691000},"page":"322-328","source":"Crossref","is-referenced-by-count":12,"title":["An alternative multiple\u2010trapping LC\u2010SPE\u2010NMR system"],"prefix":"10.1002","volume":"30","author":[{"given":"Steven Ray","family":"Wilson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helle","family":"Maler\u00f8d","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dirk","family":"Petersen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frode","family":"Rise","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elsa","family":"Lundanes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tyge","family":"Greibrokk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,2,13]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.2183\/pjab.54.194"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)95270-1"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac50057a032"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-458X(199802)36:2<104::AID-OMR230>3.0.CO;2-F"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.834"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac970142k"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(98)00316-1"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac0347819"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.1637"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.1196"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.1617"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.1742"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200500359"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/jms.589"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.270.5244.1967"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrc.1616"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemosphere.2005.09.034"}],"container-title":["Journal of Separation Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjssc.200600238","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jssc.200600238","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T09:10:37Z","timestamp":1760865037000},"score":1,"resource":{"primary":{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/10.1002\/jssc.200600238"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,2]]},"references-count":17,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2007,2]]}},"alternative-id":["10.1002\/jssc.200600238"],"URL":"https:\/\/doi.org\/10.1002\/jssc.200600238","archive":["Portico"],"relation":{},"ISSN":["1615-9306","1615-9314"],"issn-type":[{"type":"print","value":"1615-9306"},{"type":"electronic","value":"1615-9314"}],"subject":[],"published":{"date-parts":[[2007,2]]}}}
