Environmental Monitoring

Although the monitoring of low-boiling VOCs using conventional GC techniques is straightforward, the latest GC×GC and detector technologies are needed to adequately tackle the analytical challenges posed by semi-volatiles and persistent organic pollutants (POPs) in complex matrices.

Hyper-fast GC–FID for analysis of total petroleum hydrocarbons

Hyper-fast GC–FID enables rapid, high-resolution analysis of total petroleum hydrocarbons while meeting ISO 16703 and ISO 9377-2 requirements. With 3.5-minute cycle times, excellent repeatability and low carryover, the approach significantly improves throughput and operational efficiency for routine environmental TPH analysis.
