TOC online analyzer

Innovative, Unique, Continuous 

On-line Monitoring of Total Organic  Carbon levels in Water Samples

Parameters

• TOC / TC (User selectable) 

• IC (Optional) 

• TN (Optional) 

• COD (by correlation)

Application Areas rs

Continuous, Online monitoring of Organic Load in various environmental process applications: 

• Surface Water 

• Municipal & Sewage Wastewater 

• Industrial Wastewater

General Specifications 

• The monitor is designed for continuous  operation 

• Measured parameters: TC or TOC, by  operator’s selection; IC and TN are optional  additions 

• Instrument has dual zone high temperature  combustion technology and the higher  temperature zone is adjustable between 600- 1000°C 

• Range is set from 0-5mg/L to 0-1,000mg/ L TOC, operator adjustable. 1000mgTOC/L is  achieved without dilution of the sample  

• Limit of Detection is 0.1mgC 

• Measuring method: High Temperature  Catalytic Oxidation (HTCO); TOC is analyzed  by direct NPOC measurement, IC removal is  achieved by air sparging and acidification 

• Sensor for carbon analysis is nondispersive  infrared detector (NDIR) 

• Analysis cycle time depends on number  of wash cycles, however it is arranged by the  operator; nominally between 5 to 20 minutes 

• Samples at 1 to 2 bar-absolute are  introduced without problem, by getting use of  internal sampling pump 

• Air flow rate is operator adjustable and  nominally about 200mL/min,  

• Sample temperature of 5°C to 50°C is  affordable  

• Fluid flow for accurate and repeatable  injection is achieved through 3 peristaltic  pumps plus a 6-port solenoid driven valve  

• Waste liquid disposal is achieved  automatically by peristaltic pump 

• Ambient temperature of between 5°C and  40°C is good for proper operation 

• Communication and available digital  outputs: via RS232; date and time, up to 3  measured parameters and error messages;  profibus, modbus and ethernet options are  available as adders 

• 0-10 VDC and 4-20 mA analog output  options are available for future upgrade 

• 2 dry contact alarm limits are set by user

• Data storage and data presentation: up  to 9999 recent results should be saved and  stored, on the basis of “first in first out” method;  graphical trend presentation is available on  the display and initiated by the operator 

• Following software functions are available: 

o System diagnostics, data storage, optional  single or multipoint calibration file storage;  single validation cycle;  

o Design of an analytical cycles as to include  as many DI wash and sample wash runs as  required; maintenance cycle management  and warning of replacement parts based on  run cycles;  

o Continuous control of sample, acid and DI  water flows, liquid leakage, furnace  

o Temperature, air flow rate; air leakage;  

o Auto-stand-by in case of: emptied acid  bottle, sample-acid-DI water leakage, air  leakage, furnace temperature failure; 

o Graphical presentation of trend between  settable date and time 

• Power requirement is 230 VAC 50/60 Hz;  1200VA 

• Carrier Gas: hydrocarbon and CO2 free air at  2-6 bar 

• Compliance with standard methods: 5310B, EPA 415.1, ISO 8245:1999,  DIN1484:1997 

• A start up kit is included in the standard pack,  for immediate commissioning to operate the  instrument at site, for limited number of runs,  however a consumables kit is recommended  for a year of smooth operation 

• Lifelong remote support is available
