GD-508 Ash Content Tester
Summary:
The instrument is suitable to determine ash content in the petroleum products as per GB/T50. It could not be used to determine ash content in the petroleum products containing ash-forming additives (including additives containing certain phosphorus compounds),lubricating oils containing lead,and used engine crankcase oils.
The method Summary:
Take ashless filter paper as ignition core. Ignite the sample in the crucible to make it burning to ash and carbon residue. Heat the carbon residue at 775C in the high temperature furnace to make it convert to ash. Then cool down and weigh the mass.
