Anal Bioanal Chem. 2008 Jan;390(2):759-68. Epub 2007 Nov 7. Determination of chlorophenoxy acids-2,4-dichlorophenoxyacetic acid (2,4-D), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2-(2,4-dichlorophenoxy) propanoic acid (2,4-DP), 2-(4-chloro-2-methylphenoxy) propanoic acid (MCPP), 4-(4-chloro-2-methylphenoxy) (MCPB) and 2-(2,4,5-trichlorophenoxy) propanoic acid (2,4,5-TP) in spiked human urine samples has been carried out by capillary LC, after solid-phase extraction on a column packed with C18 restricted-access material. |

The 2,4-D analog, 2-methyl-4-chlorophenoxyacetic acid (MCPA), gave a similar response with both methods, whereas other phenoxy herbicides cross-reacted differently. When a concentration step, with disposable C18 extraction columns, was used, the limit of sensitivity was 5 micrograms/L. |

J AOAC Int. 1999 Jul-Aug;82(4):968-81. LODs for the rest of the analytes except bentazone, captan, decamethrin, and MCPA are 0.05-0.1 microgram/L. On-line HPLC analysis is performed with a 15 cm C18 analytical column eluted with a mobile phase of (pH = 3)-acetonitrile in 25 min linear gradient mode. |

The pesticides and herbicides determined were 2,4-dichlorophenoxy (2,4-D), 2-methyl-4-chlorophenoxy (MCPA), dichlorprop, mecoprop, 2,4, 5-trichlorophenoxy (2, 4, 5-T), 2-methyl-4-chlorophenoxy (MCPB), beta-endosulfan, methoxychlor and 2, 2-bis (p-chlorophenyl)-1, 1-dichloroethene (DDE). The extract was analyzed using an SGE C18 column with a linear gradient elution - as mobile phase at a flow rate of 0.8 mL/min) and ultraviolet detection at 230 nm. |

J Chromatogr A. 2008 Aug 22;1202(2):163-72. Epub 2008 Jul 9. The selected pesticides represent a broad range of polarity and volatility [benzoylcyclohexanedione (mesotrione and sulcotrione); chloroacetamide (acetochlor, alachlor, dimethenamide, and metolachlor); phenoxyacetic acid (2,4-D and MCPA); phenoxypropionic (dichloprop and mecoprop); phenylurea (chlortoluron, diuron, isoproturon, linuron, and metoxuron); sulfonylurea (foramsulfuron, iodosulfuron, and nicolsulfuron); triazine (atrazine, cyanazine, desethylatrazine (DEA), desisopropylatrazine (DIA), simazine, and terbutylazine)]. The separation was carried out on an acquity UPLC BEH C18 column (1.7 microm, 50 mm x 1 mm ID) using a gradient elution profile and mobile phase consisting of 0.1% in water and acetonitrile. |

J Chromatogr A. 2001 Dec 14;938(1-2):23-33. Four types of soils, including sand, clay and peat, with a range in organic matter content of 0.3-13% and ten acidic pesticides of different chemical families (bentazone, bromoxynil, metsulfuron-methyl, 2,4-D, MCPA, MCPP, 2,4-DP, 2,4,5-T, 2,4-DB and MCPB) were selected as matrices and analytes, respectively. The latter consisted of the selection of a 5-microm GFF-II internal surface reversed-phase (ISRP, Pinkerton) analytical column (50 x 4.6 mm, I.D.) as the first column in the RAM-C18 configuration in combination with an optimised linear gradient elution including on-line cleanup of sample extracts and reconditioning of the columns. |

J Chromatogr A. 2001 Jul 20;923(1-2):75-85. A rapid and sensitive LC-electrospray tandem mass spectrometry method has been developed for the quantitation of 4-chloro-2-methylphenoxyacetic acid (MCPA) and 4-chloro- in both water and soil samples. Soil samples were extracted in alkaline media and cleaned-up by solid-phase extraction with C18 cartridges before LC-MS analysis. |
