An end to fragile packed glass columns Improved efficiencies Faster analysis times Extremely inert packing Bonded phases Simple installation Conventional GC convenience Tested and guaranteed columns
Alltech 0.53 mm fused silica open tubular NON-PAKD columns offer the best of both worlds of capillary columns and pack columns. Now many analyses done by packed GC columns can be done with NON-PAKD columns with greater ease, through-put, and efficiency.
A Thing of the Past.. .
Allied Analytical Systems offers an approach to fur nace atomic absorption that takes the worry out of furnace interferences. Our new system is based on the following: • The NEW IL755CTF™ Controlled-Temperature Fur nace Atomizer with the Delayed Atomization Cuvette (DAC) which reduces vapor phase interferences by delaying atomization and causing atoms to be released into a hotter temperature environment. • The IL FASTAC®llautosampler,a flame/furnace aero sol sampling system that not only automates sample introduction, but actually reduces solid phase interfer ences by eliminating the drying step associated with conventional autosamplers. • The SMITH-HIEFTJE System. A surprisingly simple but effective background correction system for correcting broadband and structured background over the entire wavelength range of atomic absorption. • Video graphics for visualization of uncorrected and background corrected signals.
