Fully Automated Mercury Analyzer for Petro products in compliance with UOP 938-20 method

The Automated Petro- Pyrolysis Mercury Analyzer (PE -1 & PE 1000) from Nippon Instrument Corporation, Japan ensures quick, ultra-highly sensitive and highly precise measurements of the trace level mercury concentration in crude oil, petroleum product, natural gas and others.

The technique used is Direct Thermal Decomposition – Gold Amalgamation – CVAFS (Fluorescence technology) for the measurement of mercury down to parts-per -trillion level.

NIC PE-1000 Mercury Analyzer

Key Features

  • Fully automated analysis of samples that are difficult to measure, such as compounds with a low boiling-point.
  • Ultra-high sensitivity measurement (0.01 ppb) achieved by the thermal decomposition atomic fluorescence spectrometry.
  • Accurate and safe measurement by a closed system.
  • 15 & 121 position auto sample changer enhances analysis efficiency.
  • Accuracy management by standard check.
  • Heating and agitating functions.
  • Analyzer management by self-check at startup.
  • Measurement with an optional mercury collector tube is possible (for Gaseous Samples).
