• 30 in/sec speed (40 in/sec available)
Spectrotherm ST-10 is not simply an improved IR system. It is a new approach to IR spectroscopy Now the chemist can get Instant''' IR spectra two seconds after the effluent leaves the analytical GC. And the system's sophisticated computer will manipulate the data in any way he desires.
• ± 0.2% accuracy
Check all these firsts
• Highest axis isolation
• It displays the IR spectrum in real time. # l t can sample GC effluent of less than 100 nanograms. # l t is completely computer-controlled. •It'provides as standard the new mercury-cadmiumtell υ ride detector that is 100 times more sensitive than the detector used in most infrared spectrometers. · I t can be used as a standard analytical IR spectrometer when not in use examining GC samples. • It offers a unique Triple Pass Gas Cell that gives the instrument three times the chance to interact with the sample.·Its efficient design utilizes all of the IR beam, not just half as in other similar IR spectro meters.#lt can trap samples in the cell for further study. #lts mini-computer utilizes 'floppy'' disks that can store up to 100 spectra per disk.
