easy-to-use.Theintelligent series offers intuitive user guidance and has beendesigned for tough routine analytical work.High-qualitymaterials and long-living components ensure a low degree of wear.Additionally few wearing parts,long maintenanceintervals and fast replacement guarantee minimum operating costs.Easily accessible wearing parts in the system facilitate maintenance.TC,TOC,TIC,NPOC,NPOC plus,POC or TNb all methods at the click of a mouseTOC determination:Total carbon(TC)and inorganic carbon(TIC)are determined separately.The difference results in theTOC,TOC=TC-TIC.This method makes it possible to determine both volatile and nonvolatile compounds.It is used in particular for the TOC determination of samples with a high TOC content and a low TIC content,e.g.,in waste water.NPOC determination:The TIC is removed from the sampleTo this end,the sample is acidified automatically and the resulting CO2 then purged by a carrier gas stream.The residual non purgeable organic carbon(NPOC)is subsequently determined via direct measurement.With the multi N/C models utilizing the flow injection principle,the parallel purging and inject feature is used to purge the next sample during the measurement.This results in time savings of up to 50%compared to the TOC differential method.The multi N/C UniqueThe multi N/C series offers the right solution for a wide range of applications.Its quality and ease of use saves time and operating costs.automatic TIC control function is especially useful to verify complete TIC elimination during NPOC operation.For most environmental and ultrapure water samples with negligible amounts of light volatile organics,the NPOC results can be set equal to TOC results.For particularly high sample throughput of drinking,well or ground water with a high natural carbonate matrix,it is recommended using our NPOC plus mode.The most reliable results and time savings up to 50%can be achieved thanks to the clever combination with the TOC difference method.POC determination:If only the volatile components ofa water sample need to be determined,the POC method quickly provides the desired information in a manner that is easy to understand.Two highly sensitive detectors are available for the TNb determination.The chemiluminscence detector(CLD)or the solid state chemodetector(ChD)measures all organic and inorganic nitrogen compounds completely and reliably.TNb is measured at the same time as the TOC determination from the same injection.No catalyst or combustion tube replacement is required,which saves time and operating costs.A separate brochure for pharmaceutical TOC/TN applications is available as well.Therein we have provided detailed information on multi N/C pharma series.4Focus Radiation

processes within the system are detected with precision and considered in the analysis.The measurement curve obtained with the help of VITA is independent of flow,which makes the TOC system much more precise,sensitive and stable.The VITA Flow Management System both guarantees the highest operating safety and reliable analysis results.An integrated highperformance gas box ensures stable gas flows by means of electronic control and adjustment of system gas flows several times a second.The test for leak tightness is performed continuously and is fully automated.The results are transmitted to the Self Check System(SCS).In the event that there are deviations from the preset control values the operator is informed automatically via a warning message.All active device functions are locked in orderto prevent incorrect analysis results at the same time.Improved precision and sensitivityVITA also allows for the fast injection of large samplevolumes in high-temperature TOC devices.Any unavoidablecarrier gas fluctuations are compensated effectively.Thissignificantly improves both the precision of measurementresults and sensitivity in the trace range.Improved stabilityAltered conditions within the analytical system,such as saltdeposits,can have a negative effect on the flow of the carrier gas and thus on the NDIR signal.VITA fights this process effectively and also improves the stability of measurementresults after prolonged reactor use,particularly in the caseof difficult samples.VITA Flow Management System guarantees the long lifetime of the catalyst withconsistently reliable results.VITA Flow Management SystemVITA Flow Management System continues to work where conventional TOC analyzers reach their limits.VITA Flow Management System Your benefits
