Transforming Industries with Advanced Gas Sensing Technology
Spectrik’s innovative photonic gas sensors are redefining air quality management and process efficiency across sectors. From agriculture and food production to industrial, energy, and environmental applications, our cutting-edge technology delivers real-time insights into gas emissions, enabling better decision-making, improved safety, and enhanced sustainability.
Step 1. Enhanced Selectivity with a Single Precision Laser
We use a laser that emits an exceptionally pure and narrow wavelength (colour) of light, precisely tuned to target the gas we want to measure. This high selectivity ensures that only target molecules are excited, while other gases have minimal to no impact on the signal—resulting in highly accurate detection.
Step 2. Smart Modulation for Energy-Efficient Sensing
A modulator introduces two slightly different wavelengths (colours) of light, enabling the sensor to detect changes in absorption within the frequency domain (Hz) rather than relying on the number of absorbed photons. This approach significantly reduces power consumption while maintaining high sensitivity.
Step 3. Integrate Everything in 1 single Photonic Chip to Improve Robustness, Scalability and Affordability
By integrating all components into one photonic chip, the sensor becomes eventually as compact as a deck of cards. This not only improves robustness by minimizing optical alignment needs but also enables scalable, cost-effective manufacturing— producing up to multiple thousands of units per batch with consistent performance (instrument repeatability).
Step 4. Isolated Measurement to Prevent any Drift or Saturation of the Sensing Elements
To prevent drift and saturation—common issues in conventional sensors—our design shields the laser and detector from direct contact with the gas. This protective approach ensures long-term accuracy and significantly extends the sensor’s operational lifetime.
Step 5. Measuring Gas Concentration Through Light Speed Shift
The two slightly different wavelengths of light travel through the gas at different speeds. By precisely measuring the phase shift between them, we determine the concentration of the target gas. This unique method allows for highly sensitive and accurate gas detection.
Step 6. Reliable Linearity Through the Beer-Lambert Law
Our sensing principle is grounded in the Beer-Lambert law, which states that light absorption is directly proportional to gas concentration. This ensures excellent linearity and simplifies calibration across a wide measurement range.
Step 7. Continuous Self-Monitoring for Verified and Reliable Data
Spectrik continuously analyzes both sensor and sample parameters to detect even the slightest drift. This real-time monitoring allows for immediate corrections, ensuring that gas concentration data remains accurate, stable, and trustworthy over time.
