Viruses that come in small, non enveloped packages are the most difficult to kill. Preliminary screening withMS2 can be auseful way to test the efficacy of potential formulations or contact times, without having to wait for results. When the sample solution-mobile phase mix reaches the column, its components will differentially interact with the stationary phase (which remains in the column) depending upon their chemical composition or physical properties. Careers. Another approach is to add blocking agents that minimize the interaction of the analyte with the inner surfaces of the containers.14. The coliphage, or MS2, is a virus that is commonly used to test the effectiveness of water filters and purifiers. Talk to your doctor about which options may be right for you.
