Industrial grade is a concept of scope. Focus on reliability and absolute accuracy of indicators. Let’s get to know the industrial grade.
Here is the content list:
l What does an industrial-grade mean？
l What is the difference between reagent grade and industrial grade?
l What is industrial purity?
Industrial grade is used in the process of production, and the specific content standard is determined according to product attributes.
Generally speaking, the military grade is the highest, followed by the industrial grade, then the commercial-grade, and finally the civilian grade.
The industrial-grade power supply is strict on the side where there is no military power supply. But there are certain requirements for waterproof and fireproof;
Commercial-grade power supplies are lower than the waterproof and fireproof requirements of industrial-grade power supplies;
The civil power supply is the power supply we generally use. It is not very strict, but there are certain requirements.
These requirements are graded, and the grades are classified according to the quality, requirements, and purpose of the power supply.
The difference between reagent grade and industrial grade: The purity of reagent grade is generally higher than that of industrial-grade, but as reported, there is not much difference. The price may be quoted by the merchant. Just like you are eating fish in a restaurant, the price you call wild is higher than that of domestic ones. They are all domestic ones. The difference lies in the price. Many of the domestic reagents are manufactured by the manufacturers themselves into small packages of industrial-grade to become reagent grade. Some things are classified according to not only purity but also individual index requirements. Such as salt, heavy metals, etc. Reagent grade introduction: GR is high-quality pure, (this is the best) purity is generally 99.99%, which is used for precision experiments; AR is analytically pure, with a purity generally above 99.5%; cp is chemically pure. AR and cp are more common in chemical shops and are used for general experiments.
Industrial purity is relative to industrial grade. What is industrial purity is introduced below?
The purity of a chemical product is the purity of the raw material, and relatively speaking, it also refers to the degree of impurity in the raw material. According to the purity, chemical raw materials can be divided into two categories: industrial purity and reagent purity. The reagent-pure raw materials can be divided into four levels according to their purity.
Premium grade pure (GR, green label, first-grade product): The main component content and purity are high, suitable for accurate analysis and scientific research determination, and some can be used as reference materials;
Analytical purity (AR, red label, secondary product): High content of main components, high purity, low interference impurities, suitable for general analysis and scientific research work;
Chemically pure (CP, blue label, grade three): high content of main components, high purity, and interference impurities, suitable for general analysis and synthetic preparation in industrial and teaching processes;
Experimental pure (LR, yellow, or brown label): The main ingredient is high, the purity is poor, and the impurity content is not selected. It is only suitable for general chemical experiments and synthetic preparation.
The purity of industrial pure (T.P. reagent, Technical grade) is lower than grade 4, which is suitable for non-strict laboratory work, such as rinsing, dissolving, or used as raw material in production, and the purity is very low.
The aforementioned industrial grade, agricultural grade, food grade, reagent grade, and analytical grade are classified according to different uses. For example, the industrial-grade is used in the process of production, and the specific content standard is determined according to the product attributes. Agricultural grade The food grade and the food-grade are used in the agriculture and food industries respectively, and the others are the same with pure reagents. Analytical grades are generally used in laboratories. 
Teaching reagents: a class of reagents that can meet the teaching purpose of students without causing deviations in chemical reaction phenomena;
Designated level (ZD): This type of reagent is a chemical reagent customized for a specific user by the quality control indicators required by the user;
High-purity reagents (EP): including ultra-pure, ultra-pure, high-purity, spectral purity, to prepare standard solutions. The quality of such reagents pays attention to the content of impurities that may cause deviations in the analysis results during the analysis process of a specific method, and interfere with the component analysis or content analysis, but does not make high requirements for the main content;
Chromatographic purity (GC): dedicated for gas chromatographic analysis, the quality index pays attention to impurities that interfere with the gas chromatographic peak, and the main component content is high;
Chromatographic purity (LC): Liquid chromatographic analysis of standard materials, the quality index pays attention to the impurities that interfere with the liquid chromatographic peak, and the main component content is high.
