Configuring the GC/MS System for Pesticide Analysis SSL Injector There are two configurations of the SSL injector for pesticide analysis: • The Optimized Geometry SSL injector upgrade option is used for injecting 1-5 μL samples at a constant temperature. Note Labile pesticides, as indicated in the list of compound classes, cannot be analyzed at optimum performance. For analysis of those compounds, the B.E.S.T. PTV injector is recommended. • The Large Volume SSL injector upgrade option allows you to introduce volumes as high as 50 μL in a standard split-splitless injector. Using Concurrent Solvent Recondensation (CSR, a Thermo Fisher Scientific patented technology) enables you to overcome the limitations of the liner’s internal volume. The solvent vapors are recondensed in the pre-column and transferred to the analytical column. CSR large volume injection can be performed manually or automatically with the AI/AS 3000 II and TriPlus autosamplers. The injection parameters for SSL are described in the following table. 36 Pesticide Analyzer Reference Thermo Scientific
