Any analyte that can be oxidized or reduced is a candidate for amperometric detection. The simplest form of amperometric detection is single-potential, or direct current (DC), amperometry. A voltage (potential) is applied between two electrodes positioned in the column effluent. The measured current changes as an electroactive analyte is ...
Double-pulsed chronoamperometry waveform showing integrated region for charge determination.. In electrochemistry, chronoamperometry is an analytical technique in which the electric potential of the working electrode is stepped and the resulting current from faradaic processes occurring at the electrode (caused by the potential step) is monitored as a function of time.
The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
The envelope detector has several drawbacks: The input to the detector must be band-pass filtered around the desired signal, or else the detector will simultaneously demodulate several signals. The filtering can be done with a tunable filter or, more practically, a superheterodyne receiver; It is more susceptible to noise than a product detector
Pulse 2 is thus counted into the spectral region denoted as P. To ensure pulses are only counted into one channel, the anti-coincidence counter prevents Pulse 1 from being recorded into P . A multichannel analyzer uses a fast ADC to record incoming pulses and stores information about pulses in one of two ways: [ 1 ]
A microwave power meter is an instrument which measures the electrical power at microwave frequencies typically in the range 100 MHz to 40 GHz.. Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element, connected via a cable to the meter proper, which displays the power reading.
Differential pulse voltammetry: An electrochemical technique similar to normal pulse voltammetry but the applied base potential is increased or decreased steadily, and the pulse height: base height ratio is kept constant. In DPV, measurements of current are taken twice during each drop, first immediately before the pulse and second before the ...
Greenleaf Whittier Pickard (February 14, 1877 – January 8, 1956) was an American electrical engineer and inventor. He was largely responsible and most famous for the development of the crystal detector, the earliest type of diode detector, although he was not the earliest discoverer of the rectifying properties of contact between certain solid materials.
