What are the advantages of non-methane total hydrocarbon analyzer

The non-methane total hydrocarbon analyzer adopts the principle of gas chromatography-hydrogen flame ionization detector, and the instrument can quickly and accurately measure the total hydrocarbons, methane, non-methane total hydrocarbons and other components in the waste gas of fixed pollution sources and unorganized emissions. Device advantages: Ethernet connection for efficient remote access; enhanced user interface and large display with one-button programming; flash memory for more data and user-downloadable software; enhanced electronic design to optimize product versatility; improved layout for easier maintenance of components. It is widely used in chemical, painting, printing and dyeing, furniture manufacturing, automobile manufacturing, pharmaceutical and other industries.

Working principle and instrument characteristics of non-methane total hydrocarbon analyzer

The non-methane total hydrocarbon analyzer uses advanced chromatographic analysis technology to analyze non-methane total hydrocarbons, which has the advantages of accurate test, high precision, good stability, high sensitivity and strong anti-interference ability. Widely used in petrochemical, industrial, exhaust monitoring, environmental monitoring, sewage treatment, bio-pharmaceutical, home environmental protection, school laboratories and other fields. It can monitor the non-methane total hydrocarbons and benzene series of stationary pollution sources, and can also monitor and warn the non-organized emission of benzene series and non-methane total hydrocarbons.

Precautions in Operation of Purge Capture Instrument

Purge and trap should take into account both purge efficiency and trap efficiency. Extraction of components that are difficult to purge, the total volume of purge gas can be increased to improve purge efficiency. At a constant purge gas flow rate, the purge time can be increased to achieve greater recovery. Increasing the flow rate of purge gas can improve the purge efficiency of gases with boiling points below 35°C, but these gases may pass through the trap due to the increase in the flow rate of purge gas, reducing the trapping efficiency. The influence of purge gas flow and purge time should be considered comprehensively, taking into account the recovery rate of all purged components.

What are the key points in the operation of the purge trap?

During the purge and trap process, sample foaming will contaminate the purge and trap system. The use of anti-foaming agents can inhibit the foaming of the sample, but may change the properties of the sample matrix and cause unknown errors in the analytical results. Inert glass microspheres were filled in the purge gas channel to prevent foaming of the sample. The use of a foam filter not only does not prevent foaming of the sample, but also easily introduces errors.

What are the characteristics of the secondary thermal analyzer

Secondary thermal analyzer is a kind of detection and analysis instrument, which is used in various research institutes, laboratories, food and drug safety testing departments, factory quality control workshops, etc., from the content of organic compounds in air, water, soil, etc. to the detection and analysis of crops, beverages, desserts and other foods.

Detailed analysis of the working principle and use characteristics of the secondary thermal analyzer

The secondary thermal analyzer is a test and analysis instrument, which has the advantages of strong sampling, analysis function, stable performance, low volatility, high temperature resistance, thermal valve box, gas path integrated design, small size and so on. Compared with the traditional thermal analyzer, these characteristics have great advantages. In terms of detection accuracy and accuracy, the detection of benzene or benzene is particularly useful. It is suitable for all kinds of research institutes, laboratories, food and drug safety inspection departments, factories and other quality control places. It is necessary to detect the content of organic compounds such as air, water and soil, and to detect and analyze crops, beverages, desserts and other foods.
