Agilent Low Thermal Mass LTM II GC Columns
Agilent J&W LTM 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 module contains a patented design that efficiently heats and cools the column for significantly shorter analytical cycle times compared to conventional air-bath GC oven techniques, while also using less power.
Modules for 7890 Series GC systems are available in a wide variety of WCOT and select PLOT column configurations. The LTM II transfer line module has two heated, temperature-programmable tubes (transfer lines) through which the column leads pass, to prevent cold spots between the oven and the column assembly. Each module attaches to a transfer line module, and the resulting assembly inserts into slots in the LTM oven door.
- Available for Agilent 7890 and 6890 Series LTM GC systems
- The capacity to run up to four column modules simultaneously, with four different temperature programs, to maximise productivity
- Rapid temperature programming rates for higher analysis speed
- Faster heating and cooling times – as low as one minute or less – for more rapid analytical cycle times and less downtime
- Excellent retention time repeatability and performance comparable to conventional GC
- Less power consumption
- Integrated module design to facilitate easy column module change
“ms” column have very low bleed characteristics, and are ideal for GC/MS applications. Low bleed stationary phases reduces column contribution to background noise, resulting in an improved signal-to-noise ratio for better sensitivity and mass spectral integrity.
