Lab Chromatograph
Focused Photonics Inc. (FPI) pioneers portable and advanced Chromatography Systems under its EXPEC series, delivering on-the-go separation and identification for volatile and polar compounds in scientific fieldwork and labs. From GC-MS/MS for trace organics to LC-MS/MS for biomolecules, our instruments enable high-resolution analysis without lab constraints.
Emission Equilibrium: The Mechanics of Stack Monitoring
Stack emission monitoring employs continuous emission monitoring systems (CEMS) to extract, condition, and analyze flue gases from industrial stacks, quantifying pollutants via optical, electrochemical, or gravimetric methods. FPI’s systems draw heated samples through probes, cool/dry them to remove moisture, then route to analyzers: UV for SO2/NOx, IR for CO/CO2, beta attenuation for PM, and chemiluminescence for O2.

Evolving from benchtop origins in the 1950s, portable variants integrate MEMS columns and ambient ionization, now fusing GC/LC with QqQ or Orbitrap MS for ppb sensitivity. FPI’s EXPEC-5231 GC-MS/MS uses electron impact ionization for volatile profiling, while EXPEC-5310 LC-MS/MS employs ESI for polar metabolites—ideal for 2025’s in-situ omics, reducing sample transport errors by 40%. Whether detecting methane plumes in atmospheric studies or VOC biomarkers in clinical samples, FPI ensures <5-minute run times, democratizing advanced separation for field scientists.
FPI Chromatography in Scientific Expeditions
