In liquid injection mode, every single injection step, e.g. fill/inject speed, pre- and post injection delay times, pre- and post syringe cleaning, variable needle penetration depths, or standard addition is individually controlled through the Combi PAL's advanced software package. LVI (Large Volume Injection) allows to inject samples up to 250µl without the usual degradation in chromatographic performance. Using the capability to inject larger volumes, you can eliminate the need to concentrate a sample through evaporation. This can translate into substantial time savings. For low volume samples the fast injection speed minimizes needle discrimination and reduces background interference which means better results with less rework. The fast injection cycle time together with the nanoliter injection mode fits perfectly into the field of fast GC applications.
