China has a long history of white spirit brewing. The regional quality has its own characteristics, including light flavor, luzhou flavor, and maotai flavor, among which there are many components in white spirit. The new detection standard of Baijiu industry GB 5009.266-2016 requires that the methanol content in Baijiu shall not exceed 25mg/L, and the detection limit of Baijiu analysis chromatography is 7.5mg/L. For white spirit analysis, the component analysis gas chromatography was launched. The instrument has the characteristics of low detection limit, high sensitivity, stable and fast startup, high degree of automation, stable performance, and high performance. It can not only meet the detection of methanol content in white spirit, but also meet the detection of various components in white spirit, helping enterprises improve the quality of white spirit.
The hydrogen generator for white spirit analysis gas chromatography is a special generator produced by our company. It is mainly composed of electrolytic cell, electrical control elements (switching power supply, automatic pressure flow regulation and flow display), gas circuit unit (gas-liquid separation device, pressure indication and gas purification) and etc. 300ml/min high-purity hydrogen generator is of cylindrical structure and adopts advanced membrane permeation technology. The working principle is that the anode of the electrolytic cell generates oxygen,cathode to generate hydrogen under the action of electric field, and the oxygen is released into the atmosphere through the liquid circuit, while the hydrogen enters the purification system and then output.
1. Attention should be paid to the adding of deionized water for daily use. The amount added each time should not exceed the upper limit of the liquid level. The frequency of adding deionized water is related to the amount of hydrogen used and the ambient temperature.
2. Replace the discolored silicone. When the bottom of the desiccant turns red, it needs to be replaced. Release the hydrogen gas from the instrument, unscrew the desiccant cylinder with counterclockwise direction, and then replace it. Ensure that the rubber surface inside the cover of the desiccant cylinder is free of desiccant adhesion. After tightening, the desiccant cylinder should be screwed on facing the drying base with moderate force.
The industrial oxyhydrogen generators adopt the alkaline electrolysis method to reduce the production cost and improve the high efficiency of electrolysis.3500L/h Oxyhydrogen flame welding machine is with flange type joint electrolytic cell,1., which can be disassembled for thorough maintenance and repair in the later stage. It is suitable for high flow gas production.
The machine uses SPE electrolysis technology to send directly purified water into the cathode chamber of the electrolysis tank, and after electrification, the anode cathode passes through a wet diaphragm to electrolyze the water.
