Conductivité thermique

Focused Photonics Inc. (FPI) empowers researchers and laboratories with cutting-edge Mass Spectrometers that illuminate the molecular landscape with extraordinary detail and speed. Our ICP-MS, triple quadrupole, and time-of-flight (TOF) systems deliver femtogram-level sensitivity for elemental and molecular analysis, accelerating breakthroughs in life sciences, environmental forensics, and materials innovation.

Harnessing Heat: The Science of Thermal Conductivity Analysis

Mass spectrometry dissects samples by ionizing molecules, accelerating them through electric fields, and separating them by mass-to-charge ratio (m/z) to generate detailed spectra. FPI’s ICP-MS variants ionize via a high-temperature plasma torch, atomizing samples into charged particles for precise quantification, while TOF systems leverage time-of-flight principles for ultra-rapid, high-resolution profiling.

Inside the Technology: How FPI’s TCD Analyzers Operate

FPI’s Thermal Conductivity Analyzers follow a streamlined process for reliable gas analysis:

Gas Sampling and Exposure: Process gas flows through a thermally isolated chamber, interacting with heated filaments or thermistors.
Thermal Response: Variations in gas conductivity alter filament temperature, shifting resistance in the Wheatstone bridge.
Signal Conversion: Digital processors translate resistance changes into concentration data, with algorithms compensating for pressure and temperature fluctuations.
Data Output: Real-time results feed to SCADA or cloud platforms, with visual dashboards for operator insights.

This robust workflow, illustrated in our interactive schematics, ensures uptime in continuous operations.
