Rapid Analysis of CLP Pesticides Using High-Temperature DB-35ms and DB-XLB Columns
This document details the application of Agilent Technologies' J&W Brand DB-35ms and DB-XLB gas chromatography columns for the rapid analysis of chlorinated pesticides (CLP). The columns utilize arylene-phase technology to provide improved thermal stability and low bleed, allowing for high oven temperatures up to 360°C and shorter analysis times compared to standard phases.
| Upper Temperature Limit | 360°C |
|---|---|
| Column ID (DB-35ms) | 0.32 mm |
| Column ID (DB-XLB) | 0.32 mm |
| Film Thickness (DB-35ms) | 0.25 µm |
| Film Thickness (DB-XLB) | 0.50 µm |
| Column Length | 30 m |
Both columns have an upper temperature limit of 360°C.
No, a simple 1 to 2 hour conditioning period is typically adequate.
The columns support EPA Method 508.1, 8151A, 552.2, and 8082.
