Grade 4.5 gas purity refers to a standard of gas that is 99.995% pure. It is commonly used in applications requiring high levels of purity, such as in laboratories, electronics manufacturing, and medical applications. The designation indicates that the gas contains very low levels of impurities, making it suitable for sensitive processes where contamination must be minimized.

No, FCC grade and food grade are not the same. FCC, or Food Chemical Codex, grade refers to a specific standard for the purity and quality of food additives and ingredients, ensuring they are safe for consumption. Food grade, on the other hand, is a broader term that indicates that a product is safe for use in food applications but may not meet the specific purity standards set by the FCC. Therefore, while all FCC grade substances are food grade, not all food grade substances meet FCC standards.

To convert (a grade) out of (a potential) into (something) out of 100 multiply (a grade) by 100 and divide the result by(a potential) So that 45 out of 50 = (45 x 100) ÷ 50 = 4500 ÷ 50 = 90% or 21 out of 30 = (21 x 100) ÷ 30 = 2100 ÷ 30 = 70%
99.999%
The purity is different.
If you are referring to chemical purity by grade, I suggest you research the following terms: ACS Grade (American Chemical Society) - highest level of purity Reagent grade - Almost as stringent as ACS USP Grade - Equivalent to ACS for many drugs NF Grade (National Formulary) - Equivalent to ACS for many drugs Laboratory Grade Purified Grade Technical Grade
Hydrogen peroxide AR (Analytical Reagent) grade is of higher purity compared to LR (Laboratory Reagent) grade. AR grade typically has a purity of 95-97%, while LR grade has a purity of around 70%, making AR grade more suitable for analytical and research applications where higher purity is required.
Research grade Hydrogen typically has a purity of 99.999% or higher. This level of purity ensures that the hydrogen is suitable for use in various laboratory and research applications where high-quality results are necessary.

No, it's not the same thing. Ethylene is a gas used to produce polyethylene (solid). "Polymer grade" is just a purity label for ethylene gas, means that this ethylene is pure enough to be used in polyethylene (or other polymer) production.

An argon gas analyzer measures the purity of Argon gas. The analyzer can be used to determine the actual content of Argon gas in a specific sample.
Technical grade chemicals are less pure than reagent grade chemicals, and are usually used in applications where there are no official standards for impurity levels.Commercial grade chemicals are prepared in volume for general industrial use. Purity levels vary but they're often comparable in purity to technical grade chemicals.
