Agilent J&W LTM (Low Thermal Mass) column modules combine a high quality fused silica capillary column with heating and temperature sensing components for a low thermal mass column assembly. The LTM column modulecontains a patented design which heats and cools the column very efficiently for significantly shorteranalytical cycle times compared to conventional air-bath GC oven techniques, while simultaneously using less power.Agilent offers LTM technology for our popular 7890 and 6890 Series GC systems, and the 5975T GC/MS.
