Agilent Technologies has introduced a new fast analysis method that can replace the traditional multi-instrument approach with a single 15-minute gas chromatography-mass spectrometry (GC-MS) analysis, reducing the analysis time and improving analysis efficiency. The new method can quickly and accurately detect trace pesticide residues in fruits and vegetables, providing a powerful guarantee for food safety.
This document details a method to improve productivity in pesticide residue analysis by replacing multiple injections with a single injection using an Agilent capillary flow three-way splitter. The system allows simultaneous acquisition of data for Mass Spectrometry (MS), Flame Photometric Detection (FPD), and Electron Capture Detection (ECD).
| Analysis Time | 15 minutes |
|---|---|
| Split Ratio | 1:1:0.1 |
| Aux Pressure | 3.8 psi |
| Splitter Height | 6.5 cm |
It splits column effluent proportionally to multiple detectors, allowing two GC detector signals to be acquired together with MS data from one injection.
Backflush removes high boilers from the column faster and at a lower temperature, cutting down analysis time and increasing column lifetime.
