Total organic halogen detector

Abstract

The invention discloses a total organic halogen detector to overcome the defects in the prior art. The total organic halogen detector comprises a sample pre-treatment and automatic sample handling system, a high-temperature combustion cracking device and a detector, wherein the high-temperature combustion cracking device is provided with a double-segment automatic temperature-control heating combustion furnace; and a cascaded drying water treatment system is connected in series between the high-temperature combustion cracking device and the detector. The total organic halogen detector has a further improvement that the cascaded drying water treatment system is formed by connecting a sulphuric acid drying tube and a membrane drying device in series. The total organic halogen detector has the advantages that: the full sample range of the total organic halogen in water samples, solid samples and liquid samples containing a great mount of grains and suspended matters can be detected at low cost; the test sensitivity is high; and the accuracy is high.

Description

Total organic halogen detector technical field The invention relates to an analysis instrument for measuring the total organic halogen content of a sample, belonging to the field of chemical analysis instruments. Background technique Total organic halogen is a total indicator of halogenated organic matter, and halogenated organic matter mainly reflects the level of disinfection by-products in the process of water chlorination and the pollution of some synthetic chemicals. Therefore, the detection and strict control of total organic halogens contained in drinking water, surface water, ground water, waste water, cooling water, industrial waste water, soil and sludge has become an important content of environmental protection, water treatment and disinfection technology research. For the determination of total organic halogens in samples, according to different working principles, high-temperature microcoulomb titration and ion chromatography are commonly used at present.

Problems solved by technology

However, this type of analyzer still has some obvious deficiencies in the actual application process of relevant units. On the one hand, the price is relatively expensive. On the other hand, this type of equipment cannot completely dry the water in the sample analysis process, making The sensitivity and accuracy of sample detection have been affected to a certain extent, and its actual application range has been limited to a certain extent.

In recent years, in response to the defects in the use of the above-mentioned equipment, many enterprises have carried out technical research and transformation, but the actual effect is not always satisfactory, either because the cost of equipment transformation is too high, or the operation of the equipment is complicated, or the detection effect is not improved enough. obvious
