Preparation and evaluation of open tubular capillary electrochromatographic column modified with carboxymethyl chitosan Via covalent coupling of epoxy group, an open tubular column covalently modified with carboxymethyl chitosan (CMC) as stationary phase was prepared. The parameters of column pretreatment, sil...
The linear solvent strength (LSS) theory of gradient elution is useful in the optimization of separations in high-performance liquid chromatography. While the fundamental parameters of this theory are defined in terms of isocratic behavior, gradient operation has been used previously to estimate those ...
Validation of Chromatographic Methods
Concentration of the drug was determined from the intensities of diffusely reflected lights. Evaluation was via peak areas with linear regression analysis. 2.5. Method validation The method was validated in accordance with ICH guidelines Q2 (R1) for evaluation of various parameters that include ...
Not very useful for qualitative analysis as spectra tend to be broad bands with little structure Quantitative analysis is the major use Always attempt to work at the wavelength of the maximum absorbance = point of maximum response = better sensitivity and lower detection limits ...

The relationship between the thin layer chromatographic retention values and the molecular structures of fifteen amino acids was studied by using back propagation artificial neural networks (ANNs). In this paper, firstly, lots of parameters of amino acids have been determined, accumulated and computed....
Then, simply classify the samples according to the different characteristic parameters on it [15]. Nevertheless, the quality of TCM determines its effectiveness and safety, the content control of active ingredients is also crucial. The measurement data at a single wavelength is used in quantitative ...
HPTLC method: to optimize TLC parameters, several developing solvents were tried as methanol:13.5 M ammonia (10:2, v/v), methanol:ammonia (33%) (10:10, v/v), methanol:ammonia (33%) (10:7, v/v). But the best resolution was achieved using developing solvent consisting of methanol:ammo...
