Editorial – analysis in gases and liquids using quantum cascade lasers
This Editorial introduces Analyst's themed collection on analysis in gases and liquids using quantum cascade lasers, guest edited by Boris Mizaikoff and Bernhard Lendl.
High performance liquid chromatography with mid-infrared detection based on a broadly tunable quantum cascade laser
We present the first realization of spectroscopic HPLC detection based on an EC-QCL light source. Sugars and other contents of different beverages were determined as examples.
A compact QCL based methane and nitrous oxide sensor for environmental and medical applications
A methane (CH4) and nitrous oxide (N2O) sensor based on a sensitive, selective and well established technique of quartz enhanced photoacoustic spectroscopy (QEPAS) was developed for environmental and biomedical measurements.
Real-time trace gas sensing of fluorocarbons using a swept-wavelength external cavity quantum cascade laser
Real-time sensing of fluorocarbons at low part-per-billion concentrations using an external cavity quantum cascade laser.
Broadband spectroscopy with external cavity quantum cascade lasers beyond conventional absorption measurements
Powerful external cavity quantum cascade lasers enable unconventional broadband absorption measurements: fiber-ATR, vibrational dichroism, and photothermal emission spectroscopy.
A quartz enhanced photo-acoustic gas sensor based on a custom tuning fork and a terahertz quantum cascade laser
An innovative quartz enhanced photoacoustic (QEPAS) gas sensing system operating in the THz spectral range and employing a custom quartz tuning fork (QTF) is described. The QTF dimensions are 3.3 cm × 0.4 cm × 0.8 cm, with the two prongs spaced by ∼800 μm.
Mid-infrared spectroscopy for gases and liquids based on quantum cascade technologies
Compact QCL based sensors combining a cylindrical cell and a QCD for gases and a microfluidic system on a waveguide for liquids.
