Environmental detection quartz tube is a high-purity quartz product mainly used for pre-treatment of atmospheric, water and soil samples in environmental monitoring. It has excellent high temperature resistance, corrosion resistance, and chemical stability, and is commonly used in analytical instruments such as atomic absorption spectrometers. It can ensure uniform heating and no pollution of samples, thereby improving the accuracy and reproducibility of detection data. It is widely used in environmental protection, scientific research, and laboratory fields.

In today's era of increasing concern for environmental quality, accurate and reliable environmental monitoring data is crucial. As one of the core components of environmental monitoring equipment, quartz tubes play an irreplaceable role in multiple key detection fields due to their unique physical and chemical properties.

Core application: The key role of quartz tubes in environmental monitoring

Quartz tube is not an ordinary glass tube, it is a special industrial glass made of high-purity silicon dioxide (SiO ₂). Its outstanding performance makes it the preferred material for the following environmental detection applications:

1. Water quality analysis (TOC total organic carbon analyzer)

Application description: In TOC analysis, water samples need to be heated and oxidized to convert organic carbon in the water into carbon dioxide for measurement. Quartz tubes, as high-temperature oxidation reaction tubes, directly carry water samples and oxidants for reaction in high-temperature and high-pressure environments.

Problem solving: It ensures long-term stable operation under strong acid, strong oxidant (such as persulfate), and high temperature (up to 150 ° C or above) conditions, avoiding pollution and corrosion problems that ordinary materials may cause, thereby ensuring the accuracy of detection data.

2. Continuous Emission Monitoring System (CEMS) for flue gas emissions

Application description: In CEMS, ultraviolet differential absorption spectroscopy (UV-DOAS) is used to measure the concentration of pollutants such as SO ₂ and NOx in flue gas. Quartz tubes are used as gas sample flow cells to allow ultraviolet light beams to pass through the measured gas.

Solution: Quartz tubes have extremely high transmittance in the ultraviolet band (far exceeding ordinary glass), ensuring signal strength and distortion free transmission, which is a prerequisite for achieving high-precision and low concentration measurements. Meanwhile, it can withstand a certain temperature during the sampling process of flue gas.

3. Air pollutant monitoring (ozone generator and detection)

Application description: In an ozone generator, a quartz tube serves as a dielectric tube to generate stable ozone under high-frequency and high-voltage electric fields, which is used for laboratory calibration or water treatment. Similarly, in instruments for detecting ozone or other reactive gases, it is also used as an inert gas pathway.

Problem solving: Quartz tubes have extremely high dielectric strength and thermal stability, can withstand the high temperature and energy generated by corona discharge, and will not be corroded by strong oxidizing gases such as ozone, ensuring efficiency and equipment lifespan.

4. Soil and solid waste detection (digestion instrument)

Application description: Quartz tubes can be used as the inner lining of digestion tanks when processing soil, sludge and other samples using microwave or electric digestion instruments.

Problem solving: Its extremely low coefficient of thermal expansion allows it to withstand drastic temperature changes without exploding, and its high purity ensures that metal ion contamination will not be introduced during the digestion process of strong acids (except hydrofluoric acid), ensuring the authenticity of subsequent analysis of heavy metals and other elements.

Product advantages: Why is quartz tube an ideal choice?

Quartz tubes stand out in the aforementioned rigorous applications due to their inherent excellent characteristics:

Extremely high thermal stability: The softening point is as high as about 1730 ° C, the coefficient of thermal expansion is extremely low, it can withstand drastic temperature changes, and the thermal shock resistance is excellent.

Excellent chemical inertness: except for hydrofluoric acid and hot phosphoric acid, it hardly reacts with other acidic substances, has strong corrosion resistance, and will not contaminate the sample.

Outstanding optical performance: It has good transmittance in the full spectrum of ultraviolet, visible, and infrared, especially with a transmittance of over 90% in ultraviolet, which is unmatched by ordinary glass.

High purity and electrical insulation: As an excellent electrical insulator, it has high purity and will not introduce impurities to interfere with the detection process.
