Empowering Cutting-Edge Research: Nexisense Full-Scenario Gas Detection Solutions for Scientific Research Institutions and Laboratories

In the forefront of scientific exploration, whether it is the preparation of new semiconductor materials, chemical analysis of deep-sea geology, or controlled experiments in biomedicine, precise control and safety monitoring of the gas environment are always core issues. Laboratories not only involve conventional flammable and explosive gases but more diversely cover highly toxic, highly corrosive, and semiconductor special gases (specialty gases).

Nexisense, with its excellent sensing technology, is committed to providing precision, stability, and intelligence gas detection systems for global universities and national research institutes, safeguarding the lives of researchers and ensuring the rigor of experimental data.

Complex Challenges in Research Environments: Special Gases and Trace Analysis

Unlike industrial scenarios, the gas risks in research environments have the characteristics of “many types, rapid changes, and high precision.”

1. Harsh Requirements for Special Gases (Electronic Special Gases)
      In microelectronics and optoelectronics laboratories, highly hazardous gases such as silane (SiH₄), germane (GeH₄), and phosphine (PH₃) are frequently used. These gases are not only highly toxic but also pyrophoric, imposing nearly stringent requirements on the response time (T90) and sensitivity of monitoring systems.

2. Corrosive By-products During Experiments
      Chemical experiments often produce hydrogen fluoride (HF), hydrogen chloride (HCl), hydrogen cyanide (HCN), and various acid mists. These substances can easily damage ordinary sensors. Nexisense ensures long-term reliability of equipment under high-pollution concentrations through corrosion-resistant materials and special intake designs.

3. Diverse Monitoring Targets
      From conventional carbon dioxide (CO₂), oxygen (O₂), hydrogen (H₂) to laboratory-specific nitrous oxide (N₂O), fluorine (F₂), chlorine dioxide (ClO₂), researchers need a comprehensive platform that can flexibly expand and support synchronous monitoring of multiple factors.

FAQ: Common Questions and Answers on Gas Detection in Scientific Research Institutions and Laboratories

Q1: When multiple experiments are conducted simultaneously in the laboratory, how to solve the cross-interference problem of gas sensors?
A1: This is the most common pain point in research environments. Nexisense adopts multi-sensor fusion algorithms and highly selective special electrochemical probes. For example, when monitoring H₂S, physical filter membrane technology is used to shield alcohol vapor interference; when monitoring O₃, differential algorithms are used to subtract NO₂ readings in the environment. We can configure dedicated algorithm solutions for specific laboratories to ensure monitoring of the “gas you want.”

Q2: Silane (SiH₄) and germane (GeH₄) are extremely dangerous. What is the warning speed of Nexisense?
A2: For semiconductor special gases, Nexisense has optimized the sensor cavity structure and signal processing logic. Our SGA series special gas modules have a response time T90 < 15 seconds. For gases with extremely low auto-ignition points, the system supports millisecond-level relay output, which can instantly trigger emergency shut-off valves (EFS).
