FFully automated system to detect impurities intoNitrogen bulk samples.
 Pentatec manufactures special rack 19’’ equipped with process instruments and analyzers. The system is able to perform all the analysis to be conform to the Pharmacopeia compliance . A software collect all results from various instruments into specific reports, and store results with all information about the specific sample analyzed.
The software perform analysis by:
 Manual start
 Remote start by input contact closure
Scheduled  start
 Remote start from badge reader station

The system can be combined with: - multiple sampling system - Sampling and auxiliary gas control  - Automatic truck loading system


  1.  Pneumatic for sampling
  2.  Personal computer
  3.  AGC TCD gascromatograph for purity
  4.  AGC THC on line gascromatograph for total hydrocarbon
  5.  Delta F analyser for trace oxigen
  6.  Infrared analyser for trace carbon monoxyde 
  7.  Infrared analyser for trace carbon dioxyde 
  8. Electrochemical analyser for moisture
  9.  Chemiluminescent analiser for nitric oxydes (NOx)

The system automatically transfer the product from field to laboratory, purge the tranfert line and flows sample to the instrumentsThe analytical station provides to: Starts analysis and print certificates Dialog with PLC by contact closures


  1.  Purity
  2.  Total hydrocarbons       m. d. l. 0,1 ppm
  3. Oxigen m. d. l. 0,1 ppm
  4.  Carbon monoxyde        m. d. l. 0,1 ppm
  5.  Carbon dioxyde              m. d. l. 1 ppm
  6.  Moisture           m. d. l. 1 ppm
  7.  Nitric oxides (NOx)       m. d. l. 0,1 ppm



  • Runs automatically and operated by an operator not necessarily expert in gas analysis.
  • It works organically with multiple analyzers by providing a single solution for managing the system of product quality
