Automated online analysis & monitoring of Sulphur Compounds: H2S / COS / CS2 / SO2 / RSH
Chroma S is a fully automatic isothermal gas Chromatograph for the analysis & monitoring of sulphur compounds.
Principle :
- Continuous, uninterrupted sampling
- Sample is injected into column for separation
- Controlled oven selects optimum temperature based on application
- detection achieved by a sulphur specific photometric double flame detector
Features :
- The double flame ensures no quenching occurs
- Automatic linearization of compounds
- Identification of compounds is based on their retention time (Elution from the column)
- Automatic data validation as standard with the internal permeation tube
VISTACHROM ® software :
Chromatotec developed software system allows :
- Remote monitoring
- Full traceability through archiving of results and QC
- Set up and control of threshold alarms
- Export of data MODBUS / MGS1 / 4-20mA /0-10V
