“…A special role in correlation methods for LC is played by gel permeation chromatography (GPC)/SEC, wherein for selected groups of chemical compounds there is a linear relationship between the elution volume and the logarithm of molar mass or, more specifically the logarithm of hydrodynamic radius of a molecule. This special feature of separation conditions in GPC/SEC is used in applications dealing with the determination of molar mass distribution and average molar mass of various types of polymers . There is a number of simple applications making use of LC as well as microflow devices for the determination of physicochemical properties of complex mixtures of low‐boiling chemical compounds …”

The paper describes a new procedure for the determination of boiling point distribution of high-boiling petroleum fractions using size-exclusion chromatography with refractive index detection. Thus far, the determination of boiling range distribution by chromatography has been accomplished using simulated distillation with gas chromatography with flame ionization detection. This study revealed that in spite of substantial differences in the separation mechanism and the detection mode, the size-exclusion chromatography technique yields similar results for the determination of boiling point distribution compared with simulated distillation and novel empty column gas chromatography. The developed procedure using size-exclusion chromatography has a substantial applicability, especially for the determination of exact final boiling point values for high-boiling mixtures, for which a standard high-temperature simulated distillation would have to be used. In this case, the precision of final boiling point determination is low due to the high final temperatures of the gas chromatograph oven and an insufficient thermal stability of both the gas chromatography stationary phase and the sample. Additionally, the use of high-performance liquid chromatography detectors more sensitive than refractive index detection allows a lower detection limit for high-molar-mass aromatic compounds, and thus increases the sensitivity of final boiling point determination.

“…Absolute molecular weight or size measurements are possible, however, when coupled to online detectors that analyze, for example, light-scattering characteristics. 56 The observed correlation based on the hydrodynamic volume became accepted as the basis of universal SEC calibration, but the interpretation of SEC data is not fully understood. 57 Both theory and computer simulations assume that the separation process is determined by the partitioning of solute particles between two phases: a dilute bulk solution phase located in the interstitial space and confined solution phases within the pores of the columnpacking material.…”

“…In order to control the level of this compound in environment, it is of great importance to develop a rapid analytical method for OP because it may lead to the growth of human cancer cells and seriously impacts the reproductive ability. So many detection methods have been found to detect OP, including a high performance liquid chromatography 1, supercritical fluid chromatography 2, micellar electro kinetic chromatography method 3, capillary electrophoresis method 4, enzyme‐linked immunoassay 5, a gas chromatography mass spectrometry 6, a liquid chromatography‐mass spectrometry method 7. These methods have the disadvantages of being complex, time‐consuming and expensive.…”

Nickel oxide and nickel co‐doped graphitic carbon nitride (NiONiGCN) nanocomposites were successfully prepared by thermal treatment of melamine and NiCl2 ⋅ 6H2O. NiONiGCN nanocomposites showed superior electrochemical catalytic activity for the oxidation of octylphenol to pure GCN. A detection method of octylphenol in environmental water samples was developed based at NiONiGCN nanocomposites modified electrode under infrared light irradiation. Differential pulse voltammetry was used as the analytic technique of octylphenol, exhibiting stable and specific concentration‐dependent oxidation signal in the presence of octylphenol in the range of 10 nM to 1 µM and 1 µM to 50 µM, with a detection limit of 3.3 nM (3S/N).
