“…the determination of drugs in serum,2 retinoids3 and pesticides. 4 In these cases either preconcentration of all components took place on the analytical column or concentration of components with long elution times took place on a guard column. In both cases, solvent with a higher organic composition was then used to execute chromatographic separation.…”

“…Pol and coworkers published the first studies on the use of a comprehensive two-dimensional liquid chromatography system, termed LC-LC, for the analysis of environmental samples in 2006. This analysis showed acidic compounds present in atmospheric aerosols were separated using a multi-dimensional chromatographic system for the first time, proving the capabilities of LC-LC systems to separate intricate mixtures that would be too difficult for 1D-LC [67].…”

“…They analyzed methanolic extracts of filters containing atmospheric aerosols and expected to find mainly polar organic compounds such as aliphatic, aromatic, and substituted carboxylic acids. Because of the combined knowledge of the elution pattern and the sensitive and accurate mass spectrum data, this innovative perspective liquid chromatography (LC-LC-TOF coupled MS) is proven to be an appropriate method for screening undiscovered acidic compounds [67,69,70].…”

Analytical Liquid Chromatography - New Perspectives

Many complex mixtures usually constitute hundreds or even thousands of individual components of interest. Such mixtures are much too complicated to be separated for analytical duties in a reasonable period of time using only a single-dimensional chromatographic method. However, if a complex mixture is separated by an initial dimension using multi-dimensional liquid chromatography, a simpler portion of that separation is collected and goes to the second dimension. Each of these fractions will be analyzed separately, allowing exceedingly complex mixtures to be resolved in a short period of time. This chapter explains the fundamental principles, theoretical discussions as well as various applications with typical examples of multi-dimensional liquid chromatography in different fields.

“…Several analytical methods have been developed for the determination of herbicides. These are HPLC with amperometric detection, 1,2 HPLC-UV [3][4][5][6][7] and GC-ECD. [8][9][10][11] However, in these methods, the separation is often complex, time consuming and involves expensive apparatus.…”

Differential Pulse Adsorptive Stripping Voltammetric Determination of Dinoseb and Dinoterb at a Modified Electrode

A sensitive adsorptive stripping voltammetric method for the determination of dinitrophenolic herbicides, dinoseb (DSB) and dinoterb (DTB) at a bare carbon paste electrode (CPE) and a clay modified carbon paste electrode (CMCPE) was developed. A systematic study of various experimental conditions, such as the pH, accumulation variables and composition of a modifier on the adsorptive stripping response, were examined by using differential pulse voltammetry. A significant improvement was observed in the sensitivity by using the present method with CMCPE. When CMCPE was used, a linear response was obtained over the concentration range 2 × 10 -10 to 3 × 10 -7 M and 6 × 10 -10 to 6 × 10 -7 M with lower detection limits of 1 × 10 -10 M and 5.4 × 10 -10 M for dinoseb and dinoterb, respectively, at an accumulation time of 100 s. The interference from other herbicides and ions on the stripping signals of both compounds was also evaluated. The described method was applied to estimate of the dinoseb and dinoterb in environmental samples.
