WebshopThe PIONA-VUV Analyzer combines the power of gas chromatography–vacuum ultraviolet spectroscopy (GC–VUV), the simplicity of VUV Analyze Software, and a suite of fuel-specific applications into an easy-to-use solution that automatically analyzes fuels in just a fraction of the time.
Characterized by very short wavelengths of light, VUV spectroscopy is a universal, mass-sensitive detection technique that provides both quantitative and qualitative data. Because almost all gas phase molecules absorb strongly in the vacuum ultraviolet region of the electromagnetic spectrum, compound-specific spectra provide excellent selectivity and unambiguous identification. VUV spectra demonstrate class similarities, so fuels analysis is greatly simplified by the PIONA-VUV Analyzer.
Even with good chromatographic separation, compounds can coelute—especially with complex samples. The PIONA-VUV Analyzer provides a powerful and automated solution: Time Interval Deconvolution (TID). TID works by slicing a chromatogram into regularly spaced time intervals, each with a unique summed absorbance spectrum. Each slice is then automatically analyzed to determine the contribution of each compound to the measured spectra. This means complex chromatograms can be easily, reliably deconvolved and analyzed, without the need for a fixed peak table.
