Scope LPG residue analyzer according to SY / T 7509 standard design and manufacturing, It is applicable to the determination of the volatiles content of LPG at 37.8 â?? when residues. The 100ml LPG sample is placed in a centrifuge tube volatile, measure and record volume of 37.8 â?? when the residue left behind. At the same time to record a certain amount of solvent and the residue on the filter paper by dropping the mixed solution generated phenomenon. Features 1.
