Скачать или смотреть Ash Content Determination in Cellulose Ether

In this video, we walk through the standard laboratory procedure for determining ash content in cellulose ether:
1️⃣ Drying the Sample – Oven dry at (105 ± 2)°C for 2 hours
2️⃣ Weighing – Record precise sample and crucible weights
3️⃣ Carbonizing – Remove volatile components on a heating plate
4️⃣ Sulfuric Acid Treatment – Break down residual organics
5️⃣ Ashing in Muffle Furnace – Complete combustion at (750 ± 50)°C
6️⃣ Final Weighing – Calculate ash content based on weight difference
You’ll also see the formula and calculation method used to obtain accurate ash content percentages.
This process helps evaluate material purity, quality consistency, and performance in industrial applications.
