Fully automated petro-pyrolysis mercury analyzer: PE series

Fully automated petro-pyrolysis mercury analyzer

PE series

Model name of PE series

Fully automated petro-pyrolysis mercury analyzer: PE-1000


The PE series, just like the MA series, specializes in mercury analysis of petroleum samples by adopting the thermal decomposition method. Mercury contained in petroleum has caused problems. It sometimes forms amalgam with metals of oil pipelines, resulting in corrosion, or degrades precious metal catalysts that are used in the petrochemical process. The PE series was developed to prevent those problems. The sample is processed in a closed-system from sampling through to measurement, which minimizes volatilization of mercury and any compounds with a low boiling-point, and ensures reliable and safe use. Also, by adopting atomic fluorescence spectroscopy, it has achieved measurement with ultra-high sensitivity and high precision.

The PE series was approved by the ASTM Standard: UOP938-10 (Total Mercury and Mercury Species in Liquid Hydrocarbons), and is now used as the global standard in the oil industries throughout the world.


The typical measuring samples are materials related to petroleum, such as naphtha, kerosene, light oil, heavy oil, crude oil, and condensate.

Also, by connecting an optional unit, you can measure gaseous samples such as LPG and LNG.

Measurement flow

For measurements using an automatic sample changer, a syringe is used when samples are automatically taken from the sealed sample vial and then injected (for measurements without any automatic sample changer, you will need to inject the sample manually using a syringe). Mercury and mercury compounds are collected into the column to be separated from hydrocarbons. Next, while the temperature of the column is kept under control, mercury compounds are decomposed by heat and mercury alone is liberated. Finally, highly sensitive measurement is performed by atomic fluorescence spectroscopy.
