ICP-6800S Inductively Coupled Plasma Optical Emission Spectrometer(Petrochemical)
Application Field
Petrochemical Inductively Coupled Plasma Optical Emission Spectrometer(ICP6800S) is a professional instrument for the petrochemical industry launched by Macylab Instruments. It can be used to determine more than 30 elements in crude oil, mainly for Fe.Na.Mg.Ni. V.Ca. Pb.Mo.Mn.Cr.Ca.Ba.As; also can be used to measure iron, manganese, lead, silicon in gasoline ,and the Wear elements of additive in lubricating oil, it also can be applied for multielement determination in base oils; for the determination of sodium in formaldehyde and the determination of oil field tracer.
