Automatic Total Nitrogen Model TNC - 250

- As the total nitrogen measurement process of this
analyzer is adopted with contact thermal
decomposition method for decomposition and with
chemiluminescence for detecting method, reagents
are not required for the measurement
- “ Help� function ( software) is employed at all of
touch panel screen to give quick reference at each
operation stage, thereby, operability and
maintenance activity are improved
- Data storage capacity becomes greater because of
the adoption of CF card ( Data storage capacity is
for approx. five years of operation)
- This analyzer is applicable to the sample containing
sea water
