domestic or public disposal systems. Return old or end-of-life equipment to the

manufacturer for disposal at no charge to the user.

3.2 Intended use

The QP 1680-TOC/TNb analyzer is intended for use by individuals who measure water quality

parameters in the laboratory.

3.3 Product overview

The QP 1680-TOC/TNb analyzer measures non-purgeable organic carbon (NPOC) and total bound

nitrogen (TNb) in aqueous samples. The analyzer also measures total carbon (TC), total inorganic

carbon (TIC) and calculates total organic carbon (TOC).

The analyzer has an integrated sampler that analyzes carbon and nitrogen in different water

matrices. The analyzer connects to a PC with the TE Instruments Software (TEIS2) for operation and

automation. Refer to Figure 1 and Figure 2.

4.1 Installation guidelines

WARNING

Fire hazard. This product is not designed for use with flammable liquids.

CAUTION

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the

personal protective equipment appropriate to the chemicals that are handled. Refer to

the current safety data sheets (MSDS/SDS) for safety protocols.

CAUTION

Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local,

regional and national regulations.

N O T I C E

This instrument is sensitive to electromagnetic and electromechanical interference. These

interferences may have an effect on the analysis performance of this instrument. Do not put this

instrument near equipment that may cause interference.

Install the instrument:

• Indoors in a clean, dry, well-ventilated and temperature-controlled location

• In a location with a flat surface to prevent the unit from movement

• In a location with minimum mechanical vibrations and electronic noise

• In a location with no electromagnetic interferences from equipment such as transmitters, power

switching, etc.

• In an environmental enclosure that supplies protection from precipitation and direct sunlight

• In a location where there is sufficient clearance to make plumbing and electrical connections

• In a location where the display is easily seen by the user

• In a location with a compatible waste container for the drain tube

4.2 Prepare the reagents and standards

WARNING

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the

personal protective equipment appropriate to the chemicals that are handled. Refer to

the current safety data sheets (MSDS/SDS) for safety protocols.

• Wear protective clothing, safety glasses or face protections and rubber gloves.

• Prepare the reagents in a fume hood.

• Use only glass or PTFE labware.

• Make sure that all of the bottles vent to air after installation.

• Make sure that the applicable accident prevention regulations are observed.

• Dispose of substances correctly and in accordance with the applicable regulations.

For NPOC and IC analysis, a solution of strong acid (e.g., HCl 3 mol/L) is added with a capacity to

transfer 300 ppm of IC from the sample vial (40 mL) into CO2. Use 500 mL of acid solution to prepare

approximately 750 NPOC samples. Adjust the acid concentration or amount of acid added based on

the sample pH or buffering strength to get a sample pH less than 2. Make sure that the sample pH is

less than 2 before the analysis.
