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.
