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

DESIGN APPROACH-standards

Compliant with NCEA-C 1282ISO 10694EN 12089EN 13137 on solid samplesEPA 4151, 4153, 9060AStandart Method, 5310B, ISO 8245EN 1484ASTM D2579TS 8195 on water samples

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

DESIGN APPROACH - TIC

TOC in solid samples IC required for TOC=TC-IC

• Auto acid dosing even in SS-Manual TRL-TOC Unique

DESIGN APPROACH - TN

TN on both SOLID AND LIQUID SAMPLES

Method for nitrogen analysis• Kjeldahl TKN• High Temperature Combustion TNb

Kjeldahl-nitrogen(TKN)= organically bound nitrogen+ammonia nitrogenTotal-bound nitrogen(TNb)= organically bound nitrogen+inorganically bound nitrogen

TNb > TKN difference being nitrates and nitrites.

DESIGN APPROACH - GCU

Before detection• Venting larger part

• Cooling, condensate separation AUTOMATED CONDENSATE DISPOSAL

• Membrane drying

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

DESIGN APPROACH – automation optionwith 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

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.

DESIGN APPROACH – high salt content

High salt content water WITHOUT HARM TO THE ANALYZERHigh 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

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

TRL-TOC ANALYZER MODELS

TRL-TOC-SS Models• TRL-TOC-SS TC-only• TRL-TOC-SS TC and IC• TRL-TOC-SS TC and TN• TRL-TOC-SS TC and IC and

TN

TRL-TOC ANALYZER MODELS

TRL-TOC-AS Models• TRL-TOC-AS solids TC-only upgradable to autosampler• TRL-TOC-AS solids TC and IC with 19 solids position autosampler• TRL-TOC-AS universal with 79 position autosampler• TRL-TN upgrade for each of the above configurations

FUTURE PLANS

TRL-???

We have C, N

What other elements???
