The First Metrology Equipment Exhibition (2024)
From October 30th to 31st, 2024, under the guidance of the State Administration for Market Regulation, the first metrology equipment exhibition (2024) sponsored by the China Metrology Association was grandly opened at the Suzhou International Expo Center. The Beijing Institute of Metrology and Testing Science (hereinafter referred to as the Metrology Institute), which belongs to the Beijing Inspection and Testing Certification Center, exhibited a variety of new products for the innovative development of the metrology service industry. Among the many exhibits, the PTR-QMS 3500 proton transfer reaction mass spectrometer from East-West Analytical Instruments Co., Ltd. attracted much attention.
At the exhibition site, the booth of the Municipal Metrology Institute attracted a large number of visitors, including technical institutions, R & D enterprises and production enterprises, who came to visit and communicate. Among the many exhibits, the PTR-QMS 3500 proton transfer reaction mass spectrometer of East-West analysis was particularly eye-catching, and visitors kept coming to watch and consult, demonstrating its strong attraction and influence.
In June 2015, East-West Analytics participated in the "National Major Scientific Instrument and Equipment Development special project initiated by the Ministry of Science and Technology. The implementation period of this project is three years. During these three years, the East-West Analytics team made unremitting efforts and finally successfully realized the industrialization of PTR-QMS 3500 proton transfer reaction mass spectrometer.
PTR-QMS 3500 Proton Transfer Reaction Mass Spectrometer stands out in the market with its excellent performance and innovative technology. This instrument has broad application prospects and can be used for trace detection of VOCs in the atmospheric environment, pathogenicity research on human exhaled gas in the medical field, and explosive analysis monitoring in the field of public safety. PTR-QMS 3500 Proton Transfer Reaction Mass Spectrometer has won many honors with its outstanding performance in scientific research and industrial applications. In 2019, the instrument won the BCEIA Gold Award, which is one of the highest honors given by the China Association for Analysis and Testing. By 2022, it won the ANTOP Award again, which further confirmed its leading position in the field of analytical instruments. In addition, the instrument was also shortlisted for the 2023 Zhu Liangyi Analytical Instrument Innovation Award, which recognizes innovative products and technologies in the field of analytical instrumentation. A series of accolades highlights its outstanding position in the industry.
PTR-QMS 3500 Proton Transfer Reaction Mass Spectrometer 
Proton transfer reaction mass spectrometry (PTR-MS) is through the proton transfer reaction between the component to be tested and the reagent ion under specific conditions to become a proton, and the charged particles are separated and detected by entering the later mass analyzer. The instrument is mainly used for the detection of volatile organic compounds (VOCs), which can be continuously monitored online in real time and continuously quantitatively measured volatile organic compounds.
The instrument features, low pressure micro glow discharge ion source, high electron density, high efficiency, anti-pollution and easy maintenance;
High-quality quadrupole mass spectrometry system ensures stable and reliable data.
The minimum detection limit can reach dozens of pptv.
Fast online real-time analysis of VOCs.
With high-efficiency soft ionization technology, the purity of reagent ions can reach more than 99.8%.
Quick and easy analysis of samples without sample concentration.
The multi-function embedded control system is safe and reliable.
Application field Environmental Science
The application of proton transfer reaction mass spectrometry in environmental science is mainly reflected in the monitoring of volatile organic compounds (VOCs). This technology has been designated by DB31/T310002-2021, DB32/T310002-2021, DB33/T310002-2021 "Yangtze River Delta Ecological Green Integrated Development Demonstration Zone Volatile Organic Compounds Voyage Monitoring Technical Specifications" One of the detection technologies used, which proves its efficiency and practicability in the field of environmental monitoring.
Medical Diagnosis
The application in medical diagnosis is mainly to study the formation mechanism and possibility of cancer by monitoring the VOC of the patient's exhaled breath, and to diagnose the possibility of diabetes by analyzing the acetone content in the exhaled breath.
Food safety monitoring and sensory evaluation of food flavor substances, such as the analysis of flavor components in coffee and tea.
