Speed Of Analysis

Flow analysis is the science of performing quantitative analytical chemistry in flowing streams. Because of its efficiency and speed of analysis, capillary electrophoresis (CE) is a prospective method for the monitoring of a flow composition withdrawn from various processes (e.g., occurring in bioreactors, fermentations, enzymatic assays, and microdialysis samples). However, interfacing CE to a various flow of interest requires further study. In this paper, several ingenious approaches on interfacing flow from various chemical or bioprocesses to a capillary electrophoresis instrument are reviewed. Most of these interfaces can be described as computer-controlled autosamplers. Even though most of the described interfaces waste too many samples, many interesting and important applications of the devices are reported. However, the lack of commercially available devices prevents the wide application of CE for flow analysis. On the contrary, this fact opens up a potential avenue for future research in the field of flow sampling by CE.

С целью изучения экстракции сорбиновой кислоты из объектов со сложной матрицей изучено межфазное распределение сорбиновой кислоты в системе сополимер N-винилформамид – 1-винил-3,5-диметилпиразол – хлорид аммония. Рассчитаны коэффициенты распределения и степень извлечения консерванта при различных соотношениях фаз и концентрации раствора сополимера. Установлено влияние рН на экстракцию сорбиновой кислоты, предложен механизм ее взаимодействия с экстрагентом. Определение сорбиновой кислоты в водно-солевой фазе осуществлено методом капиллярного электрофореза в выбранных условиях.       ЛИТЕРАТУРА Luk E., Yager M. Konservanty v pishevoy promyshlennosti.

An innovative method is validated for the analysis of ertapenem sodium by capillary electrophoresis using potassium phosphate buffer 10 mM pH 7 and 15 kV voltage, in the concentration range of 70 to 120 μg mL−1. Ertapenem had a migration time of 3.15 minutes and the linearity curve was y = 2281.7 x - 24495 with a R2 = 0.9994. Thus, we propose a routine analysis method that meets the principles of green analytical chemistry for the routine analysis of ertapenem sodium by capillary electrophoresis.
