LC-MS is suitable for the analysis of polar and non-polar compounds, as well as thermolabile molecules. To minimize contamination:- High-purity solvents, water and reagents should be used for the preparation of mobile phases.- Freshly prepared mobile phases must be used to minimize the chance of microbial contamination of aqueous mobile phase and polymerization of acetonitrile (ACN).- Use of soap or detergent to clean glassware should be avoided as they can be hard to remove and can cause interference during analysis.- High purity gases (e.g., commonly used nitrogen gas of purity > 95%) must be used.- Nitrogen generators must be well-maintained and the gas cylinder must be replaced when the pressure falls below the acceptable level.- Analytes must be extracted from the sample matrix and chromatographic parameters optimized to improve the resolution of analyte peaks from interfering peaks. Performing preliminary screens with MS2 can allow you to test a large number of potentially efficacious formulations or evaluate multiple contact times without waiting weeks for results.
