Product Introduction
The SOLAFACT 2000 High-Sensitivity Rapid Gas Chromatograph Analyzer is designed for quantitative detection of ppb to ppm level gaseous (or vapor) chemicals. This instrument is based on fast gas chromatography analysis technology and utilizes highly sensitive surface acoustic wave sensors. It features high detection sensitivity, low measurement error, short detection times, good repeatability, and high reliability. Users can add databases to enable broad-spectrum measurements of various substances.
The instrument employs ultra-high sensitivity surface acoustic wave sensors, which react to the concentration characteristics of substances by causing frequency changes on the sensor crystal surface as the substance flows through. After each analysis, the instrument can be cleaned using high-temperature baking to ensure the accuracy of the next analysis. The instrument provides various portable accessories, making it an ideal choice for both laboratory and on-site testing environments.
Features
- Quantitative detection
- Simple operation.
- Extremely high detection sensitivity, down to 1 ppb
- Strong interference resistance, suitable for various application scenarios
- Ultra-fast chromatographic separation technology, capable of achieving chromatographic separation within 10 to 30 seconds.
Technical Description
Surface acoustic wave (SAW) sensors can be used to measure the concentration or mass of volatile and semi-volatile organic compounds in gases. They are characterized by high precision, small size, low power consumption, and rapid response. When gas passes through the sensor, it deposits on the sensor’s surface, causing a change in mass, which in turn leads to a change in the resonant frequency. After mixing frequencies, the output signal reflects the mass of deposited gas on the sensor and, indirectly, the current gas concentration.
