Optimizing Sensitivity in GC–FID Analysis

It is often possible to achieve better sensitivity and lower limits of detection and quantitation using standard gas chromatography instrumentation. Paying attention to fundamental variables-like sample solvent, initial oven temperature hold, carrier gas operating mode, and thermal gradients- can lead to much improved method performance.
