1. INTRODUCTION TO TRL-TOC / TN JUNE 2014, ANKARA Bülent ATAMER

2. DESIGN APPROACH-samples TOC/TC/TN/IC analysis in samples soil waste water fertilizers biomass sludge and sediments Implying heterogenity Imposing large sample size High carbon content

3. DESIGN APPROACH-standards Compliant with NCEA-C 1282 ISO 10694 EN 12089 EN 13137 on solid samples EPA 4151, 4153, 9060A Standart Method, 5310B, ISO 8245 EN 1484 ASTM D2579 TS 8195 on water samples

4. DESIGN APPROACH-oxydation for TC Carbon needs to be oxydized in order to be detected Proper oxidation technique: HTC HTC of high carbon loading! Patent pending furnace design –2 zones –İsokinetic sampling –TRL catalyst –Relatively lower temperature in the catalyst furnace

5. DESIGN APPROACH - TIC TOC in solid samplesIC required for TOC=TC-IC Auto acid dosing even in SS-Manual TRL-TOCUnique

6. DESIGN APPROACH - TN TN on both SOLID AND LIQUID SAMPLES Method for nitrogen analysis KjeldahlTKN High Temperature CombustionTNb Kjeldahl-nitrogen(TKN)= organically bound nitrogen+ammonia nitrogen Total-bound nitrogen(TNb)= organically bound nitrogen+inorganically bound nitrogen TNb > TKNdifference being nitrates and nitrites.

7. DESIGN APPROACH - GCU Before detection Venting larger part Cooling, condensate separation AUTOMATED CONDENSATE DISPOSAL Membrane drying

8. DESIGN APPROACH - detection CO2 by NDIR –Range up to 100% carbon in the sample –Easy to service –Reliable –Well known technology NO by ChL –Range up to percentages in the sample –Most sensitive

9. DESIGN APPROACH – automation option with an intelligent AUTOSAMPLER of sample loading for overnight operation and unattended operator handling both liquid and solid samples on the sample tray as much sample as possible of solid samples operator selected TOC=NPOC and TOC=TC-IC measurements on liquid samples TC and IC on the same solid sample; to get TOC results minimum bench space of the equipment manual or auto dilution of liquid samples validation once every settable sample runs calibration correction based on validation measurement, in case of drift full event logging for detailed assessment of fault messages and failures flexible result presentation and report generation capability

10. Automation (continued) sample addition/replacement on the tray, during a sequence run auto-mode shift different methods, temperatures and flow parameters in the same sequence different method, calibration and analysis requirement settings for each sample on the tray auto gas leak check during the run auto self diagnostics during the run as well as operator’s diagnositics protection of the equipment under critical risk conditions, like power failure, etc auto calibration task repeat runs of solid and liquid samples as many times as programmed intelligent reaction by the A/S if the sample amount is enough or not etc. and many more.

11. DESIGN APPROACH – high salt content High salt content waterWITHOUT HARM TO THE ANALYZER High dissolved solids content water İnject/load sample into the horizontal furnace Horizontal furnace operates at high temperatures but does not contain catalyst Ash out every time with solid samples. No remains of salt in the furnace. No remains on the surface of the catalyst, because the catalyst sits in the second furnace

12. DESIGN APPROACH – high suspended solids 2 ways As a solid sample in sample boat As a liquid sample in vial: flow route accepts up to 1mm particles

13. TRL-TOC ANALYZER MODELS TRL-TOC-SS Models TRL-TOC-SSTC-only TRL-TOC-SSTC and IC TRL-TOC-SSTC and TN TRL-TOC-SSTC and IC and TN

14. TRL-TOC ANALYZER MODELS TRL-TOC-AS Models TRL-TOC-ASsolids TC-onlyupgradable to autosampler TRL-TOC-ASsolids TC and IC with 19 solids position autosampler TRL-TOC-ASuniversal with 79 position autosampler TRL-TN upgrade for each of the above configurations

15. FUTURE PLANS TRL-??? We have C, N What other elements???
