Water samples are filtered to remove suspended particulate matter\r\nand then are pumped through disposable solid-phase extraction cartridges\r\ncontaining octadecyl-bonded porous silica to remove the herbicides. The\r\ncartridges are dried using carbon dioxide, and adsorbed herbicides are\r\nremoved from the cartridges by elution with 1.8 milliliters of hexaneisopropanol\r\n(3:1). Extracts of the eluants are analyzed by capillary-column gas\r\nchromatography/mass spectrometry with selected-ion monitoring of at least\r\nthree characteristic ions. The method detection limits are dependent on\r\nsample matrix and each particular herbicide. The method detection limits,\r\nbased on a 100-milliliter sample size, range from 0.02 to 0.25 microgram per\r\nliter. Recoveries averaged 80 to 115 percent for the 23 herbicides and 2\r\nmetabolites in 1 reagent-water and 2 natural-water samples fortified at levels\r\nof 0.2 and 2.0 micrograms per liter.", "description": "26 p.", "publisher": { "@type": "Organization", "name": "U.S. Geological Survey" }, "author": [ { "@type": "Person", "name": "Sandstrom, Mark W. sandstro@usgs.gov", "givenName": "Mark W.", "familyName": "Sandstrom", "email": "sandstro@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-0006-5675", "url": "https://orcid.org/0000-0003-0006-5675" }, "affiliation": [ { "@type": "Organization", "name": "Branch of Analytical Serv (NWQL)", "url": "https://www.usgs.gov/labs/national-water-quality-laboratory" }, { "@type": "Organization", "name": "WMA - Laboratory & Analytical Services Division", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "Office of Water Quality", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "National Water Quality Laboratory", "url": "https://www.usgs.gov/labs/national-water-quality-laboratory" } ] }, { "@type": "Person", "name": "Wydoski, Duane S. dwydoski@usgs.gov", "givenName": "Duane S.", "familyName": "Wydoski", "email": "dwydoski@usgs.gov" }, { "@type": "Person", "name": "Schroeder, Michael P.", "givenName": "Michael P.", "familyName": "Schroeder" }, { "@type": "Person", "name": "Zamboni, Jana L.", "givenName": "Jana L.", "familyName": "Zamboni" }, { "@type": "Person", "name": "Foreman, William T. wforeman@usgs.gov", "givenName": "William T.", "familyName": "Foreman", "email": "wforeman@usgs.gov", "affiliation": [ { "@type": "Organization", "name": "National Water Quality Laboratory", "url": "https://www.usgs.gov/labs/national-water-quality-laboratory" } ] } ], "funder": [ { "@type": "Organization", "name": "National Water Quality Laboratory", "url": "https://www.usgs.gov/labs/national-water-quality-laboratory" } ] } }, "OpenAlex": { "abstract_inverted_index": { "A": [ 0 ], "method": [ 1, 97, 110 ], "for": [ 2, 133 ], "the": [ 3, 51, 66, 78, 134 ], "isolation": [ 4 ], "of": [ 5, 73, 77, 90, 150 ], "organonitrogen": [ 6 ], "herbicides": [ 7, 62, 136 ], "from": [ 8, 65, 120 ], "natural": [ 9 ], "water": [ 10 ], "samples": [ 11, 28, 146 ], "using": [ 12, 57 ], "solid-phase": [ 13, 42 ], "extraction": [ 14, 43 ], "and": [ 15, 36, 60, 105, 137, 143, 152 ], "analysis": [ 16 ], "by": [ 17, 68, 82 ], "capillary-column": [ 18, 83 ], "gas": [ 19, 84 ], "chromatography/mass": [ 20, 85 ], "spectrometry": [ 21, 86 ], "with": [ 22, 70, 87 ], "selected-ion": [ 23, 88 ], "monitoring": [ 24, 89 ], "is": [ 25 ], "described.": [ 26 ], "Water": [ 27 ], "are": [ 29, 38, 55, 63, 80, 100 ], "filtered": [ 30 ], "to": [ 31, 49, 122, 130 ], "remove": [ 32, 50 ], "suspended": [ 33 ], "particulate": [ 34 ], "matter": [ 35 ], "then": [ 37 ], "pumped": [ 39 ], "through": [ 40 ], "disposable": [ 41 ], "cartridges": [ 44, 54, 67 ], "containing": [ 45 ], "octadecyl-bonded": [ 46 ], "porous": [ 47 ], "silica": [ 48 ], "herbicides.": [ 52 ], "The": [ 53, 96, 109 ], "dried": [ 56 ], "carbon": [ 58 ], "dioxide,": [ 59 ], "adsorbed": [ 61 ], "removed": [ 64 ], "elution": [ 69 ], "1.8": [ 71 ], "milliliters": [ 72 ], "hexaneisopropanol": [ 74 ], "(3:1).": [ 75 ], "Extracts": [ 76 ], "eluants": [ 79 ], "analyzed": [ 81 ], "at": [ 91, 148 ], "least": [ 92 ], "three": [ 93 ], "characteristic": [ 94 ], "ions.": [ 95 ], "detection": [ 98, 111 ], "limits": [ 99 ], "dependent": [ 101 ], "on": [ 102, 114 ], "sample": [ 103, 117 ], "matrix": [ 104 ], "each": [ 106 ], "particular": [ 107 ], "herbicide.": [ 108 ], "limits,": [ 112 ], "based": [ 113 ], "a": [ 115 ], "100-milliliter": [ 116 ], "size,": [ 118 ], "range": [ 119 ], "0.02": [ 121 ], "0.25": [ 123 ], "microgram": [ 124 ], "per": [ 125, 155 ], "liter.": [ 126, 156 ], "Recoveries": [ 127 ], "averaged": [ 128 ], "80": [ 129 ], "115": [ 131 ], "percent": [ 132 ], "23": [ 135 ], "2": [ 138, 144 ], "metabolites": [ 139 ], "in": [ 140 ], "1": [ 141 ], "reagent-water": [ 142 ], "natural-water": [ 145 ], "fortified": [ 147 ], "levels": [ 149 ], "0.2": [ 151 ], "2.0": [ 153 ], "micrograms": [ 154 ] }, "apc_list": null, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5064940982", "display_name": "Mark W.
