The measurement system consists of high-speed camera (Photron), voltage probe (Rigol
), PC oscilloscope (PicoScope), and spectrometer (Jobin-Yvon Triax 552).
A DG4062 Series waveform generator (Rigol
Technologies Inc., USA) (frequency range: up to 60 MHz; voltage range: up to 10 V), which applies a sinusoidal AC voltage for inducing the DEP force in the microhole on a single electrode, was used.
A voltage square wave with an amplitude of [+ or -]10V (20 V peak-to-peak), 50% of duty cycle, and frequency of 1 Hz (Figure 5(a)) was applied through a function generator, model Rigol
DG1022, in order to produce the cycles of charge and discharge on the samples and eliminate the polarization effect.
Bellach, mae'r holl ysbryd hwnnw wedi mynd a'r byd yn ol yn ei rigol
DS2072A digital oscilloscope controlled by a Matlab was used for data processing.
Then, samples were loaded on the reversed phase column (Agela, 5 [micro]m, 150 ?, 4.6 mm x 250 mm,) and separated on an L-3000 HPLC system (Rigol
, China) at a flow rate of 1 ml/min.

Technologies USA Inc.'s DG1000Z Arbitrary Waveform Generator with SiFi Technology creates a new class of instrument for engineers who need to generate arbitrary waveforms.
DSA series of spectrum analysers, available from Telonic Instruments, is suited to performing near-field probing, conducted, and emitted pre-compliance measurements.
