3 www.HidenAnalytical.com Quadrupole Mass Spectrometers for Advanced Science The Hiden HPR-20 QIC EGA is configured for continuous analysis of gases and vapours from thermogravimetric analysers (TGA). Operating to 200°C, the QIC (quartz inert capillary) flexible 2m capillary inlet provides fast response times of less than 300 ms. The HPR-20 QIC EGA system has a mass range of 200 AMU (300, 510 AMU options) and a detection capability from 100% to less than 100 ppb. Dual rotary pump configuration provides enhanced pumping for light gases. Introduction

8 www.HidenAnalytical.com Quadrupole Mass Spectrometers for Advanced Science Fast Response to Permanent Gases / Vapours Data shows the response of a HPR-20 system to gas and vapour during switching between a dry He stream and a wet H 2 and Ar flow. For clarity, only the H 2 and H 2 O data is shown in the graph.

10 www.HidenAnalytical.com Quadrupole Mass Spectrometers for Advanced Science Soft Ionisation Unique to Hiden gas analysis systems, soft ionisation allows users to selectively ionise different gases by setting the ionisation energy for a particular mass. This powerful technique can simplify the analysis of otherwise complex cracking patterns from multi-component gas/vapour mixtures. The ionisation energy can be altered from 4 to 150 eV, in 0.1 eV increments. Standard operation is at 70 eV.
