VUV Analytics’ VGA-101 detector is the most recent advancement in vacuum ultraviolet (VUV) detection. The detector has a higher allowable maximum operating temperature and an expanded wavelength spectrum. It is based on the novelties introduced by VGA-100, the world’s first benchtop VUV spectrometer.
The VGA-100 is a universal mass-sensitive gas chromatography (GC) detector that offers quantitative and qualitative data with exceptional selectivity and sensitivity. The VGA-101 has been engineered as a next-generation detector that deals with advanced application needs.
VGA-101’s extended wavelength spectrum of 120–430 nm offers exclusive selectivity for complicated structures like polyaromatic hydrocarbons (PAHs). The potential to run the VUV detector at temperatures as high as 430 °C enables compounds with a high boiling point to be analyzed.
