New IONICON Extended Volatility Range (EVR) PTR-MS

Ultra-Fast Time Response Even for IVOCs & SVOCs

Real-Time Ultra-Sensitive trace VOC analyzers from IONICON are known for their response times in fractions of a second and hence are often used to follow rapidly changing processes and VOC signals. However, some substances are known to show a slower instrumental response because of unwanted surface interactions. These substances are either highly polar or have a reduced volatility and are typically classified as „sticky“ compounds.

IONICON’s new EVR PTR-MS: ultra-fast response times for IVOCs & SVOCs

With IONICON’s new Extended Volatility Range (EVR) setup we minimize unwanted surface interactions and still preserve all the advantages of our fully pressure controlled inlet system. This extends our sub-second response from VOCs to a wide range of compounds in the intermediate-volatility range (IVOCs, e.g. 2-tridecanone and vanillin) and even reduces the response of semi-volatile species (SVOC) like cis-pinonic acid to single-digit seconds.
