LTM Column Modules
NEW!
Agilent J&W LTM Column Modules
• Suitable for majority of Agilent J&W Capillary GC columns (30 m maximum length)
• Rapid temperature programming rates of up to 1800°C/min
• Fast cooling times – less than one minute for some configurations
• Excellent retention time repeatability, comparable to conventional GC
• Ability to run up to four column modules simultaneously, using different
temperature programs
• Works with 7890/6890 GC injectors and detectors for little change to your
existing methods
• Compatible with Agilent Capillary Flow Technology, for multi-dimensional GC
LTM column modules combine a fused silica capillary column with heating and temperature
sensing components wound around it. The design heats and cools the column very efficiently
for significantly shorter analytical cycle times compared to conventional air-bath GC oven
techniques, while simultaneously using less power.
LTM column modules are available in two column assembly sizes: 5 inch diameter (standard)
and 3 inch diameter (small). The standard format provides faster cooling speeds than the
small format. Since the chromatography quality is basically equivalent for the two module
sizes, Agilent recommends the 5 inch (standard) configuration.
When utilizing the 3 inch (small) configuration, up to four column modules can be installed
per Agilent LTM system, enabling multidimensional GC applications. With the 5 inch (standard)
configuration, two column modules can be installed per Agilent LTM system. Module sizes can
be mixed so that one 5-inch column module can be used with either one or two 3 inch
column modules.
The majority of Agilent J&W Capillary GC columns can be used for LTM column modules,
including Wall Coated Open Tubular (WCOT) columns and Porous Layer Open Tubular (PLOT)
columns. Any capillary GC column with column length up to 30 meters can be put into the
5 inch format. The 3 inch format is limited to capillary GC columns with column inner
diameters (ID) of 0.32 mm or smaller. The 3 inch format is not recommended for PLOT
columns or any capillary column that is known to be especially fragile.
All LTM column modules come standard with the following:
• Two 1 meter guard columns (deactivated fused silica tubing) of the same internal diameter
as the analytical column, one each for inlet and detector
• Package of five non-reusable ferrules that are appropriate for the dimensions of the guard
columns and analytical columns
