Features

TOC measurement by acidify and sparge TOC also know as non-purgeable organic carbon (NPOC)
TOC determination by difference between total carbon (TC) and inorganic carbon (IC) TOC = TC - IC (requires option)
TOC determination by addition method of NPOC and purgeable organic carbon (POC) TOC = NPOC + POC (requires option)

TOC-4200 offers sample automatic dilution functions (×2 to ×50) as standard.
When measuring an acid, strong alkaline, or inorganic salt sample that may damage the instrument or consumables, the effect can be alleviated by diluting the sample.
A single high standard can be auto-diluted to make a multi-point calibration curve for laboratory time saving effort.

Off-line sample measurements can be performed in the standby time periods, even during on-line operation.

The instrument internal memory can store 20,000 measured values (equivalent to one year's data at a 30-minute measuring cycle), 100 calibration values (equivalent to weekly automatic calibration over one year), and history of 100 alarms.
Six calibration curves can be saved for each measurement type (TC, NPOC, IC*, POC*, and TN*) to simplify switching between operation conditions.
USB port fitted as standard below the touch screen. Measured values and measurement conditions can be saved to USB memory. Measured results are saved as CSV files to simplify the management and processing of large quantities of data.
*Optional

Instrument operation, readout of measured values, and checking for alarms can be performed via the RS-485 or RS-232C (option). This function is convenient when managing multiple instruments.

Periodic measurements of pre-selected control samples. This can be used to monitor the condition of the instrument. Automatic calibration can be performed when a certain reference value is exceeded.
