规格：3m*1/8

型号：GDX-104

应用：
GB 1886.228-2016 食品安全国家标准 食品添加剂 二氧化碳

GBT6052-2011工业液体二氧化碳

"水溶液气味,味道及外观"是食品级二氧化碳产品中一项极其重要的感官评价指标,在GB 10621-2006标准中,它是对质量要求中已量化的及未明确限定的杂质给出一个综合的终端限制.二氧化碳产品的主要原料来自于各种工业废气及地下气井,不同的生产原料和生产工艺生产的二氧化碳产品中,产生异味的物质不同,感官的味道亦差别很大.如:油的味道多源于烃类杂质的;醇类,醛,醚类等含氧有机物会呈现淡淡的酒香及甜味;硫化物则有着强烈的恶臭及腐味.在硫化物以总硫方式控制合格的前提下,发酵尾气回收的二氧化碳产品中可能产生异味的杂质通常为醇,醛,醚,酮,酯等含氧有机物.当"水溶液气味,味道及外观"检验不合格时,应通过仪器分析确定"异味源",并给出定量分析结果,以免因为人的感观差异而导致对检测结果产生异议.另外针对发酵尾气原料,在建议二氧化碳提纯工艺时,要考虑对未知有机物的去除,确保生产出合格的产品.

"Aqueous solution smell, taste and appearance" is an extremely important sensory evaluation index in food-grade carbon dioxide products. 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 raw materials and production processes, the substances that produce peculiar smells are different, and the sensory tastes are also very different. For example: oil The taste is mostly derived from hydrocarbon impurities; oxygen-containing organic compounds such as alcohols, aldehydes, and ethers will present a faint wine aroma and sweetness; sulfides have a strong stench and rot. On the premise that the impurities that may produce peculiar smell in carbon dioxide products recovered from fermentation tail gas are usually oxygen-containing organic compounds such as alcohols, aldehydes, ethers, ketones, and esters. Determine the "odor source", and give the quantitative analysis results, so as to avoid objection to the test results due to the difference in human perception. In addition, for the fermentation tail gas raw material, when recommending the carbon dioxide purification process, the removal of unknown organics should be considered to ensure that Produce qualified products.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses GDX-104 packed column to determine vinyl chloride, acetaldehyde, ethylene oxide, methanol and benzene in food-grade carbon dioxide, with high column efficiency, good separation, and area external standard method for quantification, Satisfied with the results.
