RJ Lee Group Fields the PTR-MS Instrument for Real-Time VOC Monitoring

RJ Lee Group News

May 1, 2012

(MONROEVILLE, Pa., May 1, 2012) RJ Lee Group, Inc., a materials characterization laboratory and industrial forensics and environmental consulting firm, recently fielded the new Proton Transfer Reaction – Mass Spectrometry (PTR-MS) instrument that allows for monitoring of volatile organic compounds (VOCs).  The PTR-MS does not require a gas supply and is Iight-weight, relatively small and portable, and requires little maintenance, allowing it to be easily mounted and operated in a mobile van in nearly every environment.

With a growing focus on air quality, including new EPA regulations requiring industry to comply with low levels of VOCs, the PTR-MS has many useful applications for the company.  These include monitoring changes in air quality over time at a single location as well as driving around to assess air quality in various locations or target sites such as schools and industrial sites.  In addition to portability, the PTR-MS presents other advantages over other instruments: ppqv to pptv detection limits, there is no sample preparation is necessary, there is low fragmentation, and it provides both real-time measurements and real-time quantification.
