- Application-specific columns, designed for analysis of organophosphorus pesticides.
- Best column combination for US EPA Method 8141A.
- Low bleed--ideal for FPD, NPD, GC/MS analysis.
- Thermally stable to 330°C.
Using sophisticated computer modeling software, Restek has created two stationary phases for separating the 55 organophosphorus pesticides listed in EPA Method 8141A. Separation is improved, and analysis time is significantly reduced, compared to other columns. The extended upper temperature limit of these phases (330°C) allows analysts to bake out high molecular weight contamination typically associated with organophosphorus pesticide samples. The low bleed columns are a perfect match for sensitive detection systems.
