On July 23, 2021, it was learned from the official website of the National Medical Products Administration (NMPA) that Hunan Burui Biotechnology Co., Ltd. (hereinafter referred to as “Burui Technology”), a wholly-owned subsidiary of Shenzhen Burui Technology, had independently developed“Mass Spectrometer for Human Exhaled Breath Analysis” Has Obtained National Class II Medical Device Registration Certification, the product is suitable for detecting and analyzing small-molecule volatile characteristic metabolites in human exhaled breath.
It is worth mentioning that this isThe world’s first platform-based product in the field of human exhaled breath detection and analysis to achieve successful commercialization and obtain NMPA certification, marking a significant milestone in the industry. Meanwhile, this product is byBurui Technology holds all intellectual property rights., is a typical Chinese creation, markingChina’s Domestic Teams Have Achieved International Leadership in Technology and Products for Breath Testing。
The “Human Exhaled Breath Mass Spectrometer” can detect and analyze small-molecule volatile organic metabolites (VOCs) in human breath samples for the diagnosis and screening of tumors and infectious diseases. It features non-invasiveness, high accuracy, rapid analysis (1 minute per sample), high throughput, low cost, and ease of operation, effectively meeting the clinical needs of in vitro diagnostic (IVD) testing.
As the sole R&D manufacturer behind this product, Burui Technology has been dedicated to research on exhaled breath metabolomics since its inception. The company independently developed Single-Photon Ionization Time-of-Flight Mass Spectrometry (SPI-TOFMS) technology, which enables precise detection of volatile organic compounds (VOCs) in human exhaled breath, thereby facilitating early screening for malignant tumors and infectious diseases. Based on the technical principles of VOC detection using SPI-TOFMS, Burui Technology submitted relevant documentation for review to the National Medical Products Administration (NMPA) as early as September 2020. With the product now having received official approval, the company will vigorously develop follow-up screening and diagnostic products for tumors and infectious diseases.
Commenting on this approval, Wang Dongjian, founder of Burui Technology, expressed his gratitude, attributing the achievement to the hard work and dedication of Burui Technology’s excellent team and the physicians at its partner medical institutions. He also noted that favorable national policies encouraging innovative medical products were a key external factor enabling the company to secure the industry’s first such certification.
Seizing Clinical Testing Demand: Breath Testing Poised to Become a Breakout Segment in the IVD Market
In clinical disease detection, non-invasive, rapid, accurate, low-cost, and easy-to-operate methods have always been core requirements. This is particularly true for infectious diseases such as tuberculosis (TB). According to WHO guidelines, the gold standard for TB detection is sputum culture. Although this method ensures high specificity, it is technically complex. Moreover, approximately 40% of TB patients do not exhibit productive cough, further complicating sputum collection. Even when sputum samples are successfully obtained, the success rate of sputum culture remains below 50%.
With China still seeing 800,000 new tuberculosis (TB) cases annually, the “sputum culture” testing method has significantly constrained TB prevention and control efforts. A large number of smear-negative patients cannot receive a definitive diagnosis, which seriously hinders early detection and timely treatment of TB.
Similarly, early cancer screening represents a significant market within clinical disease detection. Compared to other in vitro diagnostic (IVD) applications, tumor early screening imposes higher requirements on both clinical test sensitivity and cost-effectiveness. It not only necessitates the identification of every potential tumor risk but also demands that testing costs be reduced to a level affordable for the general population. Clinically, although molecular diagnosis-based disease detection methods can ensure high sensitivity and specificity, their per-capita cost—ranging from several thousand to nearly ten thousand yuan—hinders their widespread adoption in clinical screening programs.
In contrast, the advantages of breath testing are more pronounced, enabling rapid and simple detection through breath analysis,Test results are available within one minute, with verified sensitivity and specificity both exceeding 95%., which is expected to disruptively transform the clinical testing pathways for various diseases in the future, becoming a major growth driver in the global IVD (in vitro diagnostics) market, valued at over $10 billion.
“For general hospitals, respiratory diseases account for the highest outpatient volume. Physicians must first consider confirming or ruling out tuberculosis and tumors. Wang Dongjian, founder of Burui Technology, stated: ‘The high compliance and low cost of breath testing can help physicians make rapid assessments, with the potential to become a routine outpatient test as essential as a complete blood count.’”
A ¥3 Billion Breath Testing Market: Domestic Leaders Emerge
In 1970, American chemist Linus Pauling used gas chromatography (GC) to detect more than 200 volatile organic compounds (VOCs) in human exhaled breath, which can be used to assess physical health and disease status. After more than 50 years of development, the correlation between VOCs and diseases has been supported by hundreds of thousands of clinical samples and documented in over 2,000 research articles included in the Human Breathomics Database, establishing strong associations between nearly 60 diseases and specific VOC biomarkers in exhaled breath.
However, in the past, due to the lack of dedicated platforms for exhaled breath analysis, the vast majority of volatile organic compound (VOC) studies were conducted using general-purpose laboratory platforms based on gas chromatography-mass spectrometry (GC-MS). This detection process requires sample adsorption and enrichment, thermal desorption, chromatographic separation, and mass spectrometric qualitative and quantitative analysis. Not only is this approach costly, but each sample also takes 2–7 hours to analyze, and the procedure demands a high level of technical expertise. Consequently, GC-MS has been limited to scientific research and has not been amenable to productization or large-scale clinical deployment.

Comparison of Principles and Performance of Several Breath Analysis Technologies
“Only by standing on the shoulders of giants can one see farther.” said Wang Dongjian, founder of Burui Technology. Burui Technology’s “Human Breath Analysis Mass Spectrometer” is based on the company’s independently developed Single-Photon Ionization Time-of-Flight Mass Spectrometry (SPI-TOFMS) technology. It enables direct sample introduction, eliminates the need for adsorption and enrichment processes, and allows for low-cost, rapid detection. This innovation thoroughly addresses many pain points in scientific research on volatile organic compounds (VOCs), making it possible to commercialize breath analysis products and facilitate their large-scale clinical application.
According to Frost & Sullivan data,In 2018, the market size of breath testing in China was approximately RMB 1.9 billion, which grew to RMB 3 billion in 2020.. AndThe diagnostic market for infectious diseases has exceeded RMB 100 billion, while the tumor diagnosis and screening market has reached the trillion-yuan level.. As people’s demands for a higher quality of life continue to rise, there is a growing pursuit of diagnostic and screening products that are more accurate, convenient, and cost-effective,VOCs Detection Industry Has Huge Potential for Future Growth。
Globally, the VOC detection industry abroad and in China started from roughly the same baseline. In 2015, when Burui Technology was founded, only Owlstone Medical in the United Kingdom had begun to advance its R&D technologies and products into clinical validation and refinement. Currently, VOC detection technologies both domestically and internationally each have their own characteristics, with no significant gap between them.
From a developmental perspective, exploring and establishing spectral libraries for multiple diseases represents a higher barrier for enterprises, built upon the foundation of hardware technological barriers. Chinese companies hold greater advantages in this regard; compared with Western counterparts, they face lower difficulties and achieve higher efficiency in acquiring clinical samples, which is more conducive to leveraging these advantages for rapid development. With the recent approval of Burui Technology’s “Human Exhaled Breath Mass Spectrometer,” it has become the world’s first dedicated detection platform for volatile organic compounds (VOCs) in exhaled breath. This positions Burui Technology with a greater opportunity to take the lead in completing the construction of its spectral library and joining the top international tier in the field of breath analysis.
As the breath testing industry develops, more companies will enter the market, leading to increasing diversification in technological approaches and products. Breath volatile organic compound (VOC) testing will form both complementary and competitive relationships with technologies such as genomics, immunomics, and proteomics. As a leader in this sector, Burui Technology will have greater opportunities to participate in the formulation of industry standards, which will facilitate its market expansion and strengthen its home-field advantage driven by technology and capital.
In the field of disease detection, Western entities currently hold the majority of influence over clinical diagnostic standards, guidelines, and clinical pathways. Therefore, companies are required not only to conduct research and promote their products domestically but also to actively collaborate with top-tier international medical and research institutions. The goal is to gain broad recognition from global industry experts and have their products and technologies included in guideline recommendations. Wang Dongjian, founder of Burui Technology, told VCBeat that although the pandemic has temporarily hindered comprehensive overseas collaboration, Burui Technology has already engaged in online communications with experts from leading research institutions such as the U.S. National Cancer Institute and Imperial College London to explore future cooperative opportunities.
