Gas chromatography mass spectrometry (GC-MS) sample preparation is performed on smaller and more volatile samples including environmental pollutants, industrial byproducts, food contaminants, pesticides, and metabolites of illicit and designer drugs. These molecules are more challenging to ionize and

2.29.1 Introduction. Sample preparation is the most labor-intensive and time-consuming step of sample analysis and is the most error-prone part of the process, as it contributes about 30% of the sources of errors. Effective sample preparation helps analytical chemists to cope with increasing demands in the laboratory.

Feb 5, 2017 · Solution stability of analytes plays an important part in qualitative analysis, especially in conducting accurate, quantitative analyses. Sample diluents and glass vials as sample containers for HPLC analyses can play a critical role and should be evaluated during chromatographic method development.

May 1, 2019 · Preparing HPLC samples using traditional syringe filters often results in the loss of some sample in the syringe. This can make it difficult to get a reading and so you might just decide to save the trouble and not to use the filter at all. This is one of the reasons why we developed the Whatman Mini-UniPrep and glass-based Mini-UniPrep G2
