The ease of use and few infrastructure requirements for AROMA systems enable long-term, unattended operation at fixed monitoring sites. A few different operating modes are available depending on the requirements of the site:
In collaboration with the Bay Area Air Quality Management District, AROMA-VOC was set up next to their dual column GC-FID for a 30-day, unattended, uninterrupted, side-by-side comparison. The results from this comparison for benzene and toluene are shown in the Proof of Performance document in the Resources section. The systems were found to be in excellent agreement with an R2 value of greater than 0.97 and 0.99 for benzene and toluene, respectively.
