GB/T 6682-2008 analytical laboratory use specifications and test methods (ISO 3696. 1987, MOD)3 Method summaryThe use of a volatile sample is formed between the body and the residue material differences between the physical and chemical properties of thermal stability and oxygen, etc., The samples were low-temperature heating evaporation, carbonation, high temperature burning, the sample body and the residue was completely separated, said the quality of the residue.4 Safety TipsSulfuric acid or hydrochloric acid used in this test method is corrosive, be careful when operating! As splashed on the skin should immediately wash with water, In severe cases should be treated immediately. This test method need to use high-temperature furnace, the operation must be careful to prevent burns.5 General ProvisionsThis standard reagents and water, did not indicate when the other requirements, refer to analytically pure reagents and GB/T 6682-2008 stipulated three Grade water.6 ReagentsHydrochloric acid solution was 6.1. 1 + 1. 6.2 sulfuric acid.7 instruments and equipment7.1 evaporation vessel. crucible or evaporating dish, made of platinum, quartz or ceramics. 7.2 high-temperature furnace. temperature can be controlled at 550 ℃ ~ 1200 ℃. 550 ℃ ~ 800 ℃, the temperature can be controlled at 550 ℃ ± 25 ℃ ~ 800 ℃ ± 25 ℃; 800 ℃ ~ 1200 ℃, the temperature can be controlled at 800 ℃ ± 50 ℃ ~ 1200 ℃ ± 50 ℃. Analysis Step 8 8.1 ignition temperature selection The sample own characteristics, select the appropriate firing temperature. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23951-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23951-2009_English as soon as possible, and keep you informed of the progress.
