solid phase extraction
A two-level orthogonal array design (OAD) to optimize the solid phase extraction of organochlorine pesticides is described.
      
This systematic approach was then used to optimize the relevant parameters required for off-line solid phase extraction of organochlorine pesticides from water.
      
Optimisation and validation of an automated solid phase extraction technique coupled on-line to enzyme-based biosensor detection
      
A fully integrated screening system for phenolic compounds was developed incorporating on-line solid phase extraction, fractionation and biosensor detection.
      
The highly fluorescence pyrrolinones were isolated and pre-concentrated by solid phase extraction.
      
The various parameters such as reaction conditions between anilines and fluram, solid phase extraction and chromatographic separation were optimized.
      
The highly fluorescence pyrrolinones were isolated and pre-concentrated by solid phase extraction.
      
The various parameters such as reaction conditions between anilines and fluram, solid phase extraction and chromatographic separation were optimized.
      
Liquid chromatographic determination of nitroaromatics in water following solid phase extraction, pre-column reduction and deriv
      
The highly fluorescent pyrrolinones were isolated and preconcentrated by octadecylsilane solid phase extraction cartridge followed by reversed-phase, high-performance liquid chromatographic analysis.
      
Various aspects such as the reduction process, derivatization, solid phase extraction and chromatographic separation were optimized.
      
The effect of passing samples through a C-18 solid phase extraction cartridge was investigated briefly, to try to simplify the sample prior to injection.
      
The method involved organic solvent extraction followed by solid phase extraction on aminopropyl column.
      
Solid phase extraction of polychlorinated biphenyls from water containing humic substances
      
A study was carried out of the recovery by solid phase extraction of the eleven most toxic polychlorinated biphenyls from water containing humic acids.
      
Samples for analysis were preconcentrated by solid phase extraction on-column with octadecyl silane packing.
      
In the last procedure two different solid phase extraction (SPE) cartridges examined makes it possible to separate PAHs and remove paraffinic compounds which is very important for the quantitative GC analysis of the PAHs.
      
This was achieved by developing an alternative and fully automated solid phase extraction procedure with on-line peak compression sample injection onto a microbore (2.1 mm i.d.) column by means of a Zymate robot.
      
The pesticides were selectively retained on a solid phase extraction column containing antibodies to chlortoluron and to isoproturon immobilised onto silica.
      
In some cases, extracts were purified prior to quantitative analysis of the DON by using solvent partitioning, and/or solid phase extraction, or immunoaffinity columns.
