Introduction: The instrument uses the microcoulomb method principle (power method), with acid extraction of organic arsenic in the sample, into AsH3, and I2 containing complex compound I2-KBr electrolyte reaction occurs by calculating the amount of electricity consumed iodine, according to Faraday electrolysis The law calculates the arsenic content of the corresponding sample. Scope of application: It is used for various catalysts such as gasoline, diesel, light and heavy naphtha, crude oil and residual oil, liquefied gas, internal gas and other catalysts. It is also suitable for all kinds of water, food, beverage and other samples. Meet the standard: in line with SH / T 0162 and other standards. Features: 1. Windows operating platform, man-machine direct dialogue, clear steps, easy to operate. 2. Computer control of the entire analysis, data processing and other processes, according to the needs of the parameters, the results save or print. 3. High sensitivity, good stability, accurate results Technical Parameters: Measuring range: 1ppb ~ ppm ~% Accuracy: 1μg / L Titration method: microcoulometry titration Input impedance:> 106Ω Output voltage: -24V ~ + 24V Bias: 0 ~ 500mV Gain: 2000 Baseline drift: <5μV / 20min Range: points high and low content of two files,> 1 ppm with high content file.
