PE-1000

Applications

• Mercury determination in petrochemical liquids: Crude oil, shale oil, condensate, naphtha, gasoline, jet fuel, kerosene
• Mercury determination in gases, LPG, LNG

A device for every application

Refineries or petrochemical plants use the PE-1000 for measurements in liquid raw materials to protect their systems against corrosion (liquid metal embrittlement).

Gas processing plants must also test their gas supply and products for mercury. Aluminum heat exchangers used in liquefaction are highly exposed to corrosion by mercury (LME effect). Most petroleum testing laboratories must also test both liquid and gaseous hydrocarbon matrices.

In this case, the PE-1000 can be optionally equipped for the analysis of gases, LPG and LNG. EX tested sampling systems for direct sampling of high pressure systems (pipeline, pressure cylinders) are available. The samples are collected on amalgamation tubes and transferred to the PE-1000 by means of a heating unit (RH-PE).

Sensitivity

The cold vapor AFS of the PE-1000 is highly sensitive and stable. It is able to achieve a detection limit of only 0.003 ng Hg and a standard deviation of less than 3% at 0.1 ng Hg.

The combination of automatic sample feeding into the vertical combustion system using an autosampler, intermediate focusing on gold traps and detection by atomic fluorescence spectroscopy (AFS) enables reliable detection down to 0.003 ng Hg in routine applications.

The samples are protected from contamination and loss of mercury in septum-sealed 2 ml standard vials.

Flexible configuration of the autosampler depending on the sample volume

The PE-1000 has been developed with flexibility in mind for a wide range of customers and laboratory requirements. It can be operated as a stand-alone system, with an operator manually injecting the sample directly via a gas-tight syringe, or alternatively equipped with an autosampler. The autosampler, with a 15-position “vortex” function for mixing the sample, works automatically and allows standards and samples to be injected without operator intervention. The sample throughput can thus be significantly increased in a fast-working laboratory with a medium sample volume. An autosampler with up to 121 positions is available as an option.
