ELSD
Unique, Full Feature Color Display
The large touch screen displays all the detector settings and conditions from
one of two screens. Simply touch the screen to modify setting, view the
chromatogram in real time, integrate the results, annotate a method, send
results to storage or a printer, and much more.
The Most Advanced ELSD is
Now the Smallest
The SofTA Model 400 ELSD incorporates SofTA exclusive
technology in a small case. This ELSD can integrate seamlessly into
existing systems. Even small or crowded labs can benefit from the superior
performance obtained with Thermo-Split™ technology. See
our technical page
Exclusive Thermo-Split™ Technology
for more details on this
exciting new concept in Evaporative Light Scattering Detection.

SofTA Features Increase
Productivity, Enhance Performance and Reduce Cost of Operation
The Model 400 is
extremely fast to set-up. Inject samples with in 30 minutes of power up by
selecting the primary method. This set of conditions is appropriate for 90% of
all HPLC applications. The Model 400 can also be optimized for superior
detection of semi-volatile analytes and very low concentrations. Less volatile
mobile phases and high flowrates are accommodated by selecting a sub-ambient
Thermo-Split temperature.
Unlike halogen light sources, the laser does not need replacement and the
intensity is maintained with internal feedback and displayed and recorded for
reproducible results.
The fully warranted Teflon nebulizer provides superior solvent and chemical
resistance, eliminates sample build-up even at high temperatures, does not
permit sample carry over or increased noise from surface leaching. Reproducible
droplet distributions are assured by thermally isolating the nebulizer from the
spray chamber and drift tube, improving reproducibility between methods.
Low gas pressure and flow requirements allows use of cylinder, house systems, or
gas generators. The pneumatic system is protected by a high pressure shut off,
and provides a signal in the event of unstable or low pressure.
Increase Productivity with Unattended Operation
The Model 400 is built for unattended operation. If the detector encounters a
deviation from one of the predefined set points, an audible signal accompanies a
electronic signal which can be used to stop the mobile phase and auto sampler. A
log of the detector set points is transmitted to a printer or storage device
along with the chromatographic data. Never again be left guessing if your
overnight runs are accurate.
