linear sweep การใช้

• The sum result is a linear sweep voltammogram of 100 礛 dopamine in phosphate buffered saline.
• However, non-linear sweeps have to be used with caution when target returns are affected by Doppler frequency shifts.
• The results obtained by using a non-linear sweep are particularly good when the time bandwidth product of the pulse is high ( T譈 > 100 ).
• Such techniques target steady state conditions and produce waveforms that appear the same when scanned in either the positive or negative directions, thus limiting them to linear sweep voltammetry.
• It can be considered as a derivative of linear sweep voltammetry or staircase voltammetry, with a series of regular voltage pulses superimposed on the potential linear sweep or stairsteps.
• It can be considered as a derivative of linear sweep voltammetry or staircase voltammetry, with a series of regular voltage pulses superimposed on the potential linear sweep or stairsteps.
• In the two examples below, the chirps have a non-linear sweep characteristic which gives a spectrum with Taylor weighting which, used alone, will achieve a sidelobe level of-20 dB on its compressed pulses.
• The RRDE setup allows for many additional experiments well beyond the capacity of a RDE . For example, while one electrode conducts linear sweep voltammetry the other can be kept at a constant potential or also swept in a controlled manner.
• By running linear sweep voltammetry and other experiments at various rotation rates, different electrochemical phenomena can be investigated, including multi-electron transfer, the kinetics of a slow electron transfer, adsorption / desorption steps, and electrochemical reaction mechanisms.
• A way of reducing the susceptibility of non-linear chirps to Doppler is to use a  hybrid scheme, where part of the spectral shaping is achieved by a non-linear sweep, but with additional spectral shaping achieved by amplitude weighting.
