Food grade carbon dioxide used in desulfurization equipment
Food grade carbon dioxide used in sulfur dioxide removal device Details:

Name: Sulfur Dioxide Removal Device
Model: HH-Sulfur dioxide removal devi
Application: Total sulfur and sulfur dioxide in food grade carbon dioxide
Applicable: Agilent, Shimadzu, Thermo Fisher, Varian, PE, Brook and other imported and domestic instruments

"Aqueous solution odor, taste and appearance" is an extremely important sensory evaluation index in food-grade carbon dioxide products. In the GB 10621-2006 standard, it gives a comprehensive list of quantified and undefined impurities in the quality requirements. Terminal restrictions. The main raw materials of carbon dioxide products come from various industrial waste gas and underground gas wells. In carbon dioxide products produced by different production materials and production processes, the substances that produce odors are different, and the sensory tastes are also very different. For example: the taste of oil Mostly derived from hydrocarbon impurities; oxygen-containing organics such as alcohols, aldehydes, ethers, etc. will show a light wine aroma and sweet taste; sulfides have a strong malodor and rancid taste. The sulfides are qualified by total sulfur control. Under the premise, the impurities that may produce odor in the carbon dioxide product recovered from the fermentation tail gas are usually oxygen-containing organic substances such as alcohols, aldehydes, ethers, ketones, and esters. When the "water solution odor, taste and appearance" test fails, it should be determined by instrumental analysis "Odor source", and give quantitative analysis results, so as not to cause objections to the test results due to human sensory differences. In addition, for the fermentation tail gas raw materials, when recommending the carbon dioxide purification process, the removal of unknown organic matter should be considered to ensure production Produce qualified products.

The sulfide detection of food-grade carbon dioxide requires a desulfurization tube, a passivated six-way valve and a four-way valve, and two injections. Unless the instrument manufacturer has finalized the model before leaving the factory, the instrument needs to be modified, which is time-consuming, labor-intensive, cost-intensive, and low-efficiency.

In order to solve the analysis of sulfide in food-grade carbon dioxide, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a unique portable sulfur dioxide removal device HH-Sulfur dioxide removal devi, which can be interconnected with gas chromatographs, with high efficiency and instrumentation. No modification is required, and it has been successfully applied to Agilent 7890B and Shimadzu 2014, with good results and accurate and reliable results.
