We have a new Agilent GCMS QQQ - 7890B+7010B.

Our task is to analyze residual amounts of pesticides in a fish matrix.

Pesticides are polychlorinated biphenyls and organochlorine pesticides (Hexachlorocyclohexanes, Heptachlor, Dichlorodiphenyltrichloroethane, Dichlorodiphenyldichloroethane, Dichlorodiphenyldichloroethylene, etc).

But in the future, the list of pesticides will constantly expand.

The concentration range is 0.0001 - 0.03 mg/kg.

 

We are now using our local sample preparation method.

But now we want to use QuEChERS to make sample preparation easier.

 

As we understand, the method AOAC 2007.01 is suits for us.

So for the first step we need 5982-5755 or 5982-5755CH.

Is it right?Or might it be better to use 5982-1010?

Do we need an additional ceramic homogenizer?

 

What about the second step?

We cannot decide what we need.

As we can see there are many possibility:

5982-0101 or 5982-0102

5982-0029 or 5982-0029CH

5982-4950

What choice is the best? What is the difference?

 

Please help.
