Recent years have seen a rapidly growing public awareness of the climate crisis and a growing demand for the transition to a green economy. Against this backdrop, there has been a renewed need for GC applications in the environmental protection industry. Analyses such as tracking organic pollutants and analyzing pesticides demand a high degree of inertness, low bleed and separation performance. GS-Tek has detailed recommendations for GC columns that meet these needs and more.
