Improving Sensitivity of Environmental GC-MS Analysis

As with many sectors, detection limits for analytes in environmental samples are becoming ever lower. This challenges every step of the analytical process from sampling, to sample preparation, and the use and implementation of instrumentation which can provide the best sensitivity. Every step must be optimized to meet these sensitivity criteria and in this article we will look at some areas of the GC-MS method which can be optimized to provide the optimum sensitivity.
