XPLORER
TX/TS Analyzer

The TE Instruments XPLORER-TX/TS is a microcoulometric combustion analyzer for the analysis of Total Halogens and Total Sulfur. The XPLORER-TX/TS blends into every laboratory environment, whether it is for R&D, refinery, chemical or petrochemical applications, this elemental analyzer handles them all without any exception. Its robustness and precision are ideal for activities in, for example, refineries or surveyor testing labs.

Features

XPLORER 

TX/TS Analyzer

  • Compact design, smallest footprint in today’s market
  • Fast generation of sample queues and application methods with TE Instruments software (TEIS)
  • Short start-up time (less than 15 minutes)
  • Fast and precise measurement of solids, liquids, gases and LPG’s
  • Compact, stackable auto sampler for high sample throughput and low cost per analysis
  • Easy to use and intuitive user interface
  • Ultra low detection limit, high stability and reliability due to the temperature controlled titration cell
  • Fast and easy switching between TX and TS analysis, resulting in high productivity
  • ASTM, ISO, IP and related international standards compliance
  • Low maintenance and cost-effective, optimal combustion and conditioning of gases results in near to zero downtime



Working principle

Samples are introduced, with the appropriate introduction module, into a furnace, where they are oxidized at high temperature. The combustion gas, carrying halide ions, is led into a sulfuric acid scrubber for rapid water and interference removal. The dried and clean gas is led into the temperature controlled titration cell, where the halide ions react with silver ions, present in the titration cell.

The amount of charge (the integral of the regeneration current over the measuring time) used to regenerate the lost silver ions, is directly related to the Halogen content of the sample.

HX + Ag+ → H+ + AgX                     Ag → Ag+ + e

Samples are introduced, with the appropriate introduction module, into a furnace, where they are oxidized at high temperature. The combustion gas, carrying Sulfur dioxide (SO2), is led into a sulfuric acid scrubber for rapid water and interference removal. The dried and clean gas is led into the temperature controlled titration cell, where the Sulfur dioxide reacts with Tri-iodine, present in the titration cell.

The amount of charge (the integral of the regeneration current over the measuring time) used to regenerate the lost Tri-iodine, is directly related to the Sulfur content of the sample.

SO2 + I3- + H2O → SO42- + 3I- + 4H3O+               2 I- → I2 + 2e                            I2 + I → I3-
