GB/T 2093-2011 Formic acid for industrial use
Replace GB/T 2093-1993
This standard specifies the product classification, requirements, test methods, inspection rules, labeling, packaging, transportation, storage, and safety of formic acid for industrial use.
This standard is applicable to industrial formic acid produced by methyl formate method and sodium formate method.
The use of physical and chemical titration method to determine the content of formic acid in the national standard has the following drawbacks:
Long analysis time, low efficiency, unable to meet the needs of industrial production testing
Requires a large amount of chemical reagents, pollutes the environment, and is not environmentally friendly
Affects the health of laboratory personnel
It is not easy to determine the purity of formic acid by gas chromatography, as formic acid has strong activity, low sensitivity, peak tailing, and corrodes the instrument. To this end, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a new technology called "Industrial Formic Acid Purity Determination New Technology Chromatographic Column" using a new method. It can directly inject samples to determine the purity of industrial formic acid without the need for sample conversion, with high efficiency and short analysis time. It has been installed and used on instruments such as Agilent, Shimadzu, Thermo Fisher Scientific, Varian, Brooke, and PE, and has achieved good results.

GB/T 2093-2011 工业用甲酸
代替GB/T 2093-1993
本标准规定了工业用甲酸的产品分类、要求、试验方法、检验规则及标志、包装、运输、贮存和安全。
本标准适用于甲酸甲酯法和甲酸钠法生产的工业用甲酸。
国标中采用理化滴定法测定甲酸的含量：存在以下缺点：
-
分析时间长，效率低下，无法满足工业生产检测的需要
-
需要大量化学试剂，污染环境，不环保
-
影响化验人员的健康
气相色谱法测定甲酸的纯度并非易事，这时因为甲酸活性强，灵敏度低，峰型拖尾，腐蚀仪器。为此，浩瀚色谱（山东）应用技术开发有限公司，采用新技术方法，研制的《工业甲酸纯度测定新技术色谱柱》，直接进样测定工业甲酸的纯度，无需样品的转化效率高，分析时间短，在安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE的仪器上安装使用，取得了不错的效果。
