Injected into quartz tube and mixed with O2, the sample burns .Then the combustion gases are routed into a titration cell and react with I3- or Ag+ . Then the analyzer detects and adds I3- or Ag+ to original concentration. In accordance with Faraday's laws of electrolysis, the detector module calculates energy they consumed and thus gets the concentration of sulfur or chlorine.

Sulfur and Chlorine Microcoulometric Titrator

KN-4929 Sulfur and Chlorine Microcoulometric Titrator

Introduction

 Injected into quartz tube and mixed with O2, the sample burns .Then the combustion gases are routed into a titration cell and react with I3- or Ag+ . Then the analyzer detects and adds I3- or Ag+ to original concentration. In accordance with Faraday's laws of electrolysis, the detector module calculates energy they consumed and thus gets the concentration of sulfur or chlorine.


Applicable Standard

ASTM D4929, ASTM D3120, ASTM D3246, ASTM D5808


Technical Parameters

  1. Measuring range:

    Sulfur: 0.1mg/kg ~ 10000mg/kg ~ %

    Chlorine: 0.3mg/kg ~ 10000mg/kg ~ %

  2. Sample type: Solid, liquid, gas (select the proper injector)

  3. Temperature control range: Ambient~1000℃±1℃

  4. Repeatability error:  X<1.0mg/kg, Cv ≤ 20%

                     1.0mg/L≤X≤10mg/k, Cv ≤ 10%

                                     X>1.0mg/kg, Cv ≤ 5%


Features

  1. Windows operating platform, the computer controls the entire analysis, data processing and other processes, be able to display the working status of the entire process. Parameters and results can be stored or printed as needed. The software can save 5000 sample data, and can realize historical data query and graphic playback, which is convenient for comparison and analysis.

  2. Adopts international popular circuits and imported components to reduce noise and improve detection sensitivity

  3. Fast analyzing speed, only 3~4min for one sample

  4. It overcomes the shortcomings of the traditional Coulometric titrator with high water quality requirements and low conversion rate. Since the upgraded instrument has reduced the need for water quality and other analysis conditions, the CRM conversion rate can easily reach between 90% and 110%, and the CRM reverse calibration deviation is not more than 5%.

  5. Adopts imported good heating wire for longer service life of the cracking furnace

  6. The data processing software has the function of automatic cut-off of over-temperature protection. When the temperature exceeds the set upper limit, the software will automatically cut off the power to protect the electric furnace wire and combustion tube.

  7. Delayed cooling function, the cooling time can be set after the analysis, and the power will be automatically turned off when the cooling is done.

  8. Gas cut-off alarm to prevent contamination of cracking tube caused by reverse suction

  9. The purpose made high-performance spiral combustion tube is especially used for the detection of halogen content in various industrial and gaseous samples containing highly volatile components. The main advantages of the combustion tube: fast injection speed (maximum 1ul/s), not easy to coke, which is beneficial to improve the accuracy of analysis results and the analysis of trace samples

  10. The unique design of the chlorine titration cell adopts an all-silver rod electrode, which requires no prior preparation. The titration tank has a long service time, no less than 4 hours. The titration cell contains 75% glacial acetic acid solution with a capacity of 35ml. Be able to complete 60 tests without maintenance. The measurement is accurate, the start-up time is short, and the maintenance amount is small. The detector is equipped with independent temperature controlling system, and the titration cell has a long service life to keep a constant temperature. The detected gas can be discharged to the outside through the hose connection or passed into the distilled water bottle for adsorption

  11. Open LIMIS database management mode, convenient for database retrieval management
