MELTFIT ONE TESTED BY ALCONTROL

“This is the last detail we needed to have a robust analysis.”

Wim Broer tested an innovative connecting device, the Meltfit One from NLISIS, that claims to eradicate all of those problems, and wanted to share his experiences with us. His conclusion was: “In the past we had problems on a regular base with leaking columns. They will leak, and their active surface will decompose the analytes. Now with the use of the Meltfit One we always have very reliable connections. The Meltfit One is easy to operate and can be used in our labs and in petrochemical routine applications in production labs.” Wim Broer: went on to say, “Coupling is a drama for most analysts, some can do it, but most analysts have trouble with it and cannot make a good connection. When we usedmetal ferrules and Pressfits, the issue was the practical handling, and getting a reliable leak tight connection., If the coupling is not leak tight, the oxygen will disturb your stationary phase and influence your results and you get tailing. The most irritating effect of leakage is that it not only occurs at the wrong moment but also when you least expect it. Often you do not know what the cause of the problem is. You may think it is the injector itself, the liner, a bad column, or a connection which may have an active surface and causes peak distortion. Before you know what it is, it costs you a lot of time.”
