Working principle
When carbonized artifacts are burned in an oxygen rich environment, carbon * is convertedCO₂Non scattering infrared detector（NDIR）detectionCO₂Convert the amount into total carbon in the sample（Tc）Content. Then, the sample is acidified, whenpHWhen the value decreases, the carbonate and bicarbonate ions in the sample are converted intoCO2，CO2Blow out and enter the non scattering infrared detector（NDIR）,detectedCO2Quantity is converted into total inorganic carbon（TIC）The content. supportTCandTICSubtract the values to obtain the total carbon of our machine（TOC）The value.
TOC=TC-TIC
When the sample is pre acidified and blown, the total inorganic carbon of the sample can be removed（TIC）And can blow out organic carbon（POC）Then test the sampleTCValue, to obtain non blowable organic carbon（NPOC）The value.

Instrument characteristics
●Control the heating temperature through software. The combustion temperature can be within200－950℃Internal regulation. optional680℃+Catalyst or900℃High temperature oxidation is any recognized oxidation method.

TOCChinese Total Organic Carbon Analysis Software
ETTOCThe Chinese operating system runs under the Microsoft Windows program, and the operation of various components of the instrument, the setting of instrument parameters, the establishment and calling of analysis methods, the setting of analysis programs, the measurement, collection and calculation of data, quality assurance, and the generation of user reports are all easily controlled.
Conduct status tests on various components of the instrument to ensure that each pump, valve, switch, etc. is operating normally.

Establish different analytical methods for specific samples. Set all parameters, including appropriate temperature, selection and calibration of sample ring, injection volume, reagent volume, measurement time, repetition rate, gas flow rate, etc.
