Delivery information
Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.
The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.

LABTOC is a fast, reliable and highly accurate system for the laboratory analysis of sample water.
Simple to use, LABTOC can be used by laboratory technicians with the minimum of training and still be relied upon to produce precisely accurate TOC and/or TC values from single or multiple samples with a range from 0-10 ppm to 0-4000 ppm.
LABTOC consists of an organics analyser, based on proven PPM PROTOC chemical technology , an auto-sampler capable of feeding between one and eighty eight separate samples to the analyser during a single run, and an lBM-compatible PC with exclusive, user-friendly software, which both controls the analytical process and monitors the results.
Competitively priced and highly flexible, LABTOC is ideal for applications where multiple
samples need to be taken from variety of areas or variable areas on a single site, or from a number .of sampling points on multiple sites for further analysis.
As such, it is suitable for use. by industry or by regulating authorities charged with monitoring widely divergent areas such as points along a river
LABTOC will also be of interest to Companies offering off-site sample analysis service to industry, water authorities in sewage receiving applications and environmental companies engaged in waste analysis and disposal contracts.
lncreasingly, the Total Organic Carbon content found in water streams is regarded as an excellent indication of water quality, and may protocols now specify TOC or TC analysis.
TOC testing can also compliment existing BOD or COD testing facilities, particularly if organics are of major importance in the analysis exercise.
LABTOC Systems can be custom-designed and built to customers own specifications and
software customised as required to meet more specialised requirements

PRINCIPLE Of OPERATION
The sample s continuously drawn in through the autosampler dip probe This is then joined by a continuous flow of acidified reactor fluid which - depending on the mode of operation - is either TC pumped directly to the injection valve, or TOC routed via an IC removal stage to the injection valve.
Once the .fresh sample has had time to flush out the injection valve it is switched by the PC for a precisely determined amount of time, diverting the flow of sample momentarily into the flow of fresh reagent which is being pumped constantly into the reactor
The organic carbon contained in the sample is then converted to CO 2 , by the UV light and the sodium persulphate. This is carried by a very constant flow of gas, firstly to a Gas Liquid Separator (GLS). The gas is finally dried by passing through a permeation dryer tube
CO 2 concentration is then measured by a solid state infrared detector which is tuned only for the detection of CO 2 . The output of the infrared is then fed back directly into the PC where the signal is measured and integrated to provide a precise measurement of TOC or TC, as required.
Control and Monitoring Options
The LABTOC analyser and auto-sampler units are controlled by an IBM compatible PC. Data produced by the analyser is sent to the PC in turn, where it can be displayed graphically and automatically stored on floppy disk for later retrieval or as a permanent record of sample data.
The PC features PPMs own exclusive Labmon TM Windows-driven software, providing a user friendly, clear and flexible means of controlling sampling and presenting sample data.
This data can then be displayed graphically and, if required, a hard copy can be made on a colour graphics printer.
