Real-time precision monitoring of airborne Hazardous Organic NESHAP (HON) VOCs
provides unsurpassed speed and precision for global environmental regulatory compliance In response to recent guidance issued by the United States Environmental Protection Agency (EPA), Syft Technologies has recently announced its rapid analysis solution for characterizing Hazardous Organic NESHAP (HON) compounds. Robust one-minute methods for sampling these toxic VOCs have been developed which leverage the unparalleled speed, sensitivity and ease of use inherent to SIFT-MS. These methods have achieved MDLs in the low- to mid- part per trillion by volume (pptV) range. SIFT-MS offers real-time, direct monitoring of VOCs and inorganic compounds in air. Its measurements offer signifi cant advantages over traditional techniques that require long sample collection times and off-site laboratory analysis. Unlike these methods, which can miss short-term fl uctuations in pollutant concentrations, SIFT-MS provides immediate and continuous data, allowing for timely detection of hazardous compounds. This capability enhances the precision of source identifi cation and enables quicker responses to potential environmental threats, ensuring more effective monitoring and protection of public health.
The new EPA regulations for fenceline monitoring of the HON compounds stipulate that alternative monitoring methods must achieve MDLs at least one-third of the action level for the monitored compounds. For any SIFT-MS method, lower MDLs are easily achieved by increasing the duration of the monitoring method. The improvement in MDL is approximately proportional to the inverse square root of the method length. For all the HON compounds recently characterized, SIFT-MS has dramatically better temporal resolution than the EPA specifi ed methods – passive and canister sampling – facilitating better source identifi cation in the event of the concentration exceeding the action level. SIFT-MS has been adopted by governmental agencies and industry worldwide for environmental monitoring. For example, the South Korean government has relied on SIFT-MS for years to monitor toxic VOCs at both federal and state levels (Langford et al. (2023a)). The US EPA has also adopted SIFT-MS for use in mobile laboratories.

real-time data Syft Technologies has announced the release of SyftEnviro environmental monitoring software. It is a comprehensive solution for visualizing environmental monitoring data collected during real-time mobile monitoring campaigns. SyftEnviro software provides an integrated interface for collecting, mapping, and analyzing environmental data. Quantitative SIFT-MS data can be geospatially mapped and visualized while on the move in a mobile lab and later compared to historical data. This user-friendly software integrates all analytical data from environmental surveys and includes an interface for data visualization, instrument control, and status updates.

SyftEnviro is designed for non-technical users to operate with ease and requires little training. It enables emission sources to be pinpointed from real-time SIFT-MS data that is geospatially mapped. Multiple compounds can be displayed simultaneously in order to compare emissions across an environmental survey. Individual compounds can be investigated more thoroughly, and areas of high concentration visualized through a customizable color gradient displayed in either heat map or histogram format.
SyftEnviro system control is designed with an intuitive interface for non-technical users to easily schedule analysis methods, view system status, confi rm GPS connection, and set alarm triggers. It features comprehensive scheduling that includes SIFT-MS methods, delays, loops, and the Performance Tune maintenance procedure. GPS sensors are easily confi gured, and connectivity is automatically confi rmed by the software. Alarm states are built into the platform and performance parameters are displayed in real-time.
SyftEnviro software is a perfect complement to the SIFT-MS mobile van solution that delivers real-time data during environmental monitoring campaigns. SIFT-MS has been used by environmental agencies worldwide in applications such as fenceline monitoring, ambient air measurement, and mobile monitoring. It is designed with speed of analysis, ease of use, and system-to-system reproducibility in mind. SIFT-MS combined with SyftEnviro provides a platform for keeping up with rapidly changing market requirements and monitoring environmental trends over time.
