Dear all,

I'm looking at LC-MS for pesticides esp. MCPA, MCPP, 2,4-D, 2,4-DB and Chlorpyrifos in drinking and surface water. I've already looked at Dionex, Perkin Elmer and Agilent (expensive one)... and I do not have any idea. We have in the lab Dionex instrument for detection of anions and Perkin Elmer for THM's & VOC's and they are really good.

Any thought on these brands and others would be welcome and really appreciated.

Many thanks for all your help.

Hello

I'd consider 3 things:
1.Limit of detection for your methods - check which provider offers better equipment (detection system)
2.Workload/samples matrix - how often you'll have to service your equipment
3.Service - it is really important thing. Check what kind of service (quality of it and price) you can expect for your instrument.

Good luck

Regards

We have used an ABSciex API3200 for these compounds in the past. They no longer make this model but you may want to look into used equipment such as this.
