Fast CLP pesticide analysis

Agilent Technologies Europe has announced that its high-temperature arylene-based stationary phases for its GC capillary columns can provide enhanced analysis and detection of CLP pesticides.

This announcement should be of particular interest to lab technicians who routinely analyse samples for pesticides in environmental matrices and pesticide residues on food products.

The recommended columns (Agilent DB-35ms for primary analysis and Agilent DB-XLB for confirmation) have high temperature limits (360C), reduced column bleed, and short analysis times.

CLP chlorinated pesticides can be analysed using hydrogen carrier gas and a fast oven ramp in less than 15 minutes cycle time, with complete baseline confirmation of the target pesticides.

The fast analysis time has the potential of increasing a laboratory's analysis throughput and profitability.

The same column pair analyses EPA 8151A phenoxy acids in slightly over 16 minutes.

The high temperature limits and 35% phenyl content make these columns very attractive for rapid analysis of polar mixtures.

Agilent says that the DB-35ms and DB-XLB columns provide a combination of selectivity, thermal stability and inertness that is unsurpassed, with increased productivity and superior results.
