PE-1000

Fully Automated Petro-Pyrolysis Mercury Analyzer

Highly sensitive, accurate and precise

PE-1000 is a benchtop Fully Automated Petro-Pyrolysis Mercury Analyzer that is designed for the measurement of mercury from liquid petroleum-based matrices such as crude oil, condensate, naphtha, and other refined liquid-fractions, accurately down to parts-per-trillion levels.  The technique used is Direct Thermal Decomposition – Gold Amalgamation – CVAFS (Fluorescence technology)

Applications

Crude Oil  |  Shale Oil  |  Condensate  |  Naphtha  |  Gasoline  |  Jet Fuel  |  Kerosene  |  Diesel Fuel

Methods

UOP-938-20

Features

In Compliance with
UOP-938-20 Method

PE-1000 is accredited and adopted under UOP-938-20. The key to method compliance ensures analysis is done in accordance with the validated procedure where there is traceability to all results obtained for any audit.

Ultra-High Sensitivity – Detection Limit as Low as 0.003 ng

CVAFS in PE-1000 is highly sensitive and stable. It is capable to achieve a detection limit as low as 0.003 ng, with CV less than 3% at 0.1 ng.

Patented Innovative Pre-Concentration/Combustion Technology

PE-1000 is equipped with an efficient pyrolyzer with accurate temperature controls to ensure complete combustion of petroleum samples.

With its patented innovative combustion technology (Patent No.: JP 4226049 & USP 8223332), PE-1000 is capable to analyze samples ranging from feedstocks like crude oil/condensate to refined liquid products like naphtha, jet fuel, etc.
With ease, all attribute to its highly efficient pyrolyzer (Quick Ramp Fast Cool) design, effectively avoided any soot formation. From sample transfer using a gas-tight syringe in the auto-liquid injector to injecting samples via a septum-sealed injection port, all these ensure no loss of any volatile analytes. Thus, accuracy and precision can be achieved easily.

Unmatched Accuracy & Precision

Fully Automated Petro-Pyrolysis – Gold Amalgamation – CVAFS

The entire sample analysis is fully automated without operator intervention. Therefore, error occurs from sample handling by human can be disregarded.

Intact Sample Integrity

Liquid petroleum samples are mostly volatile and their volatility causes loss of analytes. In PE-1000, all samples are placed in a septum-sealed 2 mL chromatography-type vial that is tightly contained, ensuring sample integrity.

Highly Consistent Injection

Automation eliminates handling errors. PE-1000 can be operated with different autosampler choices – 15-positions or 121-positions. Mechanize auto-liquid preparation, extraction and injection in the autosampler ensure consistent and precise sample volume transfer, thus improving precision.

Excellent Sample Homogeneity

Sample homogeneity is crucial in trace-level analysis. PE-1000 is engineered with a vortex effect mixer in the autosampler to allow a good mix to the sample before an aliquot is taken for injection. This ensures sample homogeneity and representing sampling on every aliquot taken for analysis.

Multi-Configurations of Autosampler – Entry to High Productivity

Standalone & Manual Injection

PE-Series is designed with versatility in mind to all customers and laboratory needs. It can be operated as a standalone system where an operator performs manual direct injection of the sample via a gas-tight syringe.

Autosampler with 15 Positions

For a fast-paced laboratory, a medium sample load autosampler can increase the laboratory’s throughput significantly.

PE-series can be operated with an autosampler of 15 positions, automating standards and samples injections without an operator’s intervention.

*New

Autosampler with 121 Positions

(A brand new autosampler for PE-Series)

With the growing demand and increasing needs for mercury analysis on both feedstocks and refined products, NIC provides the latest autosampler for any heavy-duty laboratory with demanding sample turnaround time.

This autosampler can accommodate up to 121 samples at one go.

Flexible & Versatile – Multiple Accessories for Different Types of Applications

It is not just refineries or petrochemical facilities having requirements to measure in liquid feedstocks to protect their plant integrity from LME (Liquid Metal Embrittlement), it is extremely crucial and steadfast for gas processing plants to monitor their gas feeds and products for mercury. Aluminum Heat-Exchangers used in liquefication processing are strongly subjected to the LME effect. 
Most petroleum testing laboratories need to measure for both hydrocarbon liquid and gaseous matrices. They would prefer their analyzer to be versatile enough to adapt to different matrices. It is always a good idea to have a powerful CVAFS unit with the capability of mercury measurement of other sample matrices.

For Gaseous Matrices – Optional Attachment of RH-PE

For Aqueous Matrices – Optional Attachment of 20 mL Impinger Kit

For Direct Hg Sampling from Processing Line – LPG Direct Amalgam Sampler

MA-3 Solo

MA-3 Solo is engineered with the need of a small, compact, cost-effective, and portable direct mercury analyzer in mind.

How Does It Work?

RH-PE is a Thermal Gas Tube Desorption Unit for application of Total Gaseous Mercury (TGM) from gaseous matrices.

Application

LPG  LNG  Natural Gas  Ambient Air and other gaseous matrices

Methods

JLPGA-S-07  |  ISO 6978-2:2005  |  ASTM D-6350-14  |  USEPA IO-5 |  ISO 17852

  • NIC Mercury Collector Tube (Also Known as Gold Trap/Gold Amalgamator) is used for sampling purposes.
  • The Mercury Collector Tube is brought back to the laboratory and desorbed using RH-PE.
  • The desorbed Gaseous Elemental Mercury is sent into PE-1000 main unit and its CVAFS detector to be measured.

After analysis, all NIC Mercury Collector Tube are reusable.

How Does It Work?

Water serves many purposes in the petroleum process, including but not limited to cooling high temperature process operations, equipment washing, steam generation, unit hydrotests, and last but not least fire fighting.

Impinger Set option is an expanded application from PE-1000 with RH-PE.
Aqueous samples from the process may be contaminated with mercury which require to be checked before discharge as waste or re-cycle into the process. The AQUA Kit is made available and have sensitivity to measure to sub-ppb detection levels with a higher volume sample (typically 20mL).

Applications

Tap Water  Process Water  | Effluent Water  and more. 

Methods

USEPA 1631e  |  ISO 17852 | ISO 20552

The AQUA Kit t is a manual setup of Reducing Vaporization Technique using an impinger set.

  • Reminder : To analyze Total Mercury content, the aqueous samples need to be acid-digested before Reducing Vaporization in Aqua Impinger unit can take place
  • The sample tube is filled with the desired aqueous sample. Reducing agent SnCl2 and H2SO4 are added into the sample tube to convert all Hg²⁺ into Hg⁰.

Sn²⁺+ Hg²⁺→Hg⁰+ Sn⁴⁺

  • Hg⁰ is purged from the sample solution and directed to a mercury collector tube located in RH-PE connecting with the impinger set where all the elemental mercury will be concentrated by gold-amalgamation.
  • This RH-PE mercury collector tube is heated and the Hg⁰ is re-purified with gold amalgam in PE-1000 before desorbed to transfer by argon into CVAFS detector for measurement.
  • Detection is capable down to the low parts-per-trillion (ppt) levels.

Note: 

To measure Total Mercury from aqueous sample, the sample must be digested chemically to break down organic mercury before reducing vaporization.
Without sample digestion, only the Hg²⁺ and Hg⁰ can be measured in this technique.

How Does It Work?

The Direct Amalgamation Gas Sampler is designed to extract high pressure liquefied or gas sample (eg. natural gas, LPG/LNG) directly out at the process pipeline (at-site) or from compressed cylinder in the laboratory (off-site).

Applications

– Natural Gas  |  LPG  |  LNG Gases contained in Compressed Cylinder 
– Work with PE-1000 or WA-5

  • Up to 2 X N160 Mercury Collector Tubes can be used at every sampling – configuring in serial or parallel flow.
  • By reducing to a lower pressure with controlled flow rate, Direct Amalgam Sampler allows direct collection gaseous elemental mercury onto Mercury Collector Tube(s).
  • The Mercury Collector Tubes are brought back to the laboratory and desorbed using RH-PE.
  • RH-PE transfers all gaseous mercury directly into PE-1000 CVAFS for measurement.

After analysis, all NIC Mercury Collector tube can be reused.
