“…In most conditions, it is found that the onset voltage of the corona discharge is a little higher than that of the electrospray [35]. Thus, lowering the spray voltage of the ESI source will avoid the troublesome corona discharges [36].…”

Although there are a lot of well established methods for monitoring enzyme-catalyzed reactions, most of them are based on changes in spectroscopic properties during the conversion of substrates to products. However, reactions without optical changes are common, which are inapplicable to these spectroscopic methods. As an alternative technique for enzymologic research, mass spectrometry (MS) is favored due to its specificity, sensitivity, and the ability to obtain stoichiometric information. In this work, probe electrospray ionization (PESI) source coupled with a time of flight mass spectrometer was employed to monitor some typical proteasecatalyzed reactions, including pepsinolysis and trypsinolysis of cytochrome c in real time. Due to the high electrical conductivity of each reaction system, corona discharges are likely to occur, which would decrease intensities of mass spectrometric signals. An ultra-fine sampling probe and an auxiliary vapor spray were adopted to prevent corona discharges. Experimental results from peptic and tryptic digestions of cytochrome c showed different and characteristic catalytic pathways. With the data presented in this study, PESI-MS can be considered as a potential tool for real-time monitoring of enzymatic reactions because of its simplicity in instrumental configuration, wide applicability under harsh conditions, and flexibility in combination with other techniques.

“…This mode of per turbation evolution is the initial stage of the develop ment of instability of the charged surface of a liquid in relation to an excess of electric charge. In practice, at W > W c , the formation of conelike protrusions is observed on the liquid surface-Taylor cones, from which the emission of small strongly charged droplets in the direc tion perpendicular to the free surface occurs [3][4][5].…”

“…1 that the wavenumber k * = α -1 (for which αk * = 1) has a peculiar property: the threshold value of the parameter W at higher than which the perturbation with such a wavenumber becomes unstable equals W * = 2, while, for all the other wavenumbers, the threshold value W c is higher. The value of the wavenumber k * = α -1 corresponds to the wave perturbations most sensitive to the presence of a surface charge from the standpoint of the instabil ity of the charged surface in relation to the electric charge [1][2][3][4][5]. It seems interesting to pay special atten tion to the drift initiated by perturbation with such wavenumber.…”

“…Frenkel [2], in which the condi tions of the development of the instability of the liquid surface in relation to an excess of electric charge were studied. This phenomenon lies in the basis of the func tion principle of such technical devices as liquid metal ion sources and installations for electrodispersion of liquids and is closely related to the theory of storm electricity (for more detail, see [3][4][5] and the literature referenced there). Despite the constant interest in studies of this type by various specialists, the regulari ties of the behavior of wave perturbations upon sub critical (insufficient for initiation of instability) values of the electric charge density are very poorly under stood to date.…”

An analytical expression is constructed to estimate the influence of a surface electric charge on the drift velocity caused by the propagation of a wave packet on a horizontal surface of an ideal fluid. It has been shown that the surface electric charge affects the drift most effectively if the wavenumber of the carrier wave is equal to the inverse value of the capillary constant. Common regularities of the drift motion are established.

The dynamics of the unidimensional straight-line motion of charged liquid droplets has been considered. Stability criterion has been derived for the jet motion of liquid droplets in a space bounded by two electrodes. The motion of an ensemble of charged droplets in a constant electric field and in a nonuniform field between a needle-like electrode and a plane has been calculated by the molecular dynamics method. Experimental data have been presented on the motion of micron and submicron charged particles formed by the electrostatic spraying of different liquids. The experimental data have been compared with the theoretical calculations and numerical simulation results.
