چکیده
A miniaturized, trace level sensor for cocaine is presented. A quantum cascade laser emitting at 1720 cm-1 is coupled to a fibred absorption flow-cell. A detection limit lower than 250 ng/mL (84 ppb) is reported. OCIS codes: (300.6340) Spectroscopy, infrared; (300.6360) Spectroscopy, laser

Mid-infrared photothermal heterodyne spectroscopy in a liquid crystal using a quantum cascade laser.
We report a technique to measure the mid-infrared photothermal response induced by a tunable quantum cascade laser in the neat liquid crystal 4-octyl-4'-cyanobiphenyl (8CB), without any intercalated dye. Heterodyne detection using a Ti:sapphire laser of the response in the solid, smectic, nematic and isotropic liquid crystal phases allows direct detection of a weak mid-infrared normal mode abso...

Optical sensors based on the interaction between molecular vibrations and mid infrared radiations attracted high attentions in the last decades. In this study, we present the development of a waveguide evanescent field sensor based on the absorption spectroscopy in liquid environments. The device consists of a single mode strip waveguide integrated with a microfluidic system. With a quantum cas...
متن کاملTowards functional group-specific detection in high-performance liquid chromatography using mid-infrared quantum cascade lasers.
A distributed feedback quantum cascade laser was applied for the first time as a powerful light source for mid-infrared (MIR) detection in liquid chromatography. Fructose and glucose in red wine were separated with an isocratic HPLC system, which was connected to a custom-made flow cell. This flow cell was constructed of two diamond windows with adjustable spacing and two hollow wave-guides for...
متن کاملNonlinear Midinfrared Photothermal Spectroscopy Using Zharov Splitting and Quantum Cascade Lasers
We report on the mid-infrared nonlinear photothermal spectrum of the neat liquid crystal 4-octyl-4'-cyanobiphenyl (8CB) using a tunable Quantum Cascade Laser (QCL). The nonequilibrium steady state characterized by the nonlinear photothermal infrared response undergoes a supercritical bifurcation. The bifurcation, observed in heterodyne two-color pump-probe detection, leads to ultrasharp nonline...
متن کاملCocaine detection by a mid-infrared waveguide integrated with a microfluidic chip.
A germanium (Ge) strip waveguide on a silicon (Si) substrate is integrated with a microfluidic chip to detect cocaine in tetrachloroethylene (PCE) solutions. In the evanescent field of the waveguide, cocaine absorbs the light near 5.8 μm, which is emitted from a quantum cascade laser. This device is ideal for (bio-)chemical sensing applications.
