Exclusive Thermo-Split™ Technology:

Highest Sensitivity - Ultimate Control

 

SofTA Thermo-Split™ Technology (Patent No. US 7,290,723 B1) has the ability to vary the split ratio smoothly over a wide range.  Our aerosol splitter combines a gentle bend with temperature controlled (heated or cooled) walls. 

 

 

 

 

 

For an easily evaporated mobile phase, the walls are heated.  As the aerosol traverses the chamber, it partially evaporates, shifting the particle size distribution low enough for essentially all the particles to negotiate the bend. 

 

 

 

 

 

For difficult to evaporate mobile phases, or high flow rates, the walls are cooled.  When the aerosol exiting the nebulizer encounters a cooled environment, it partially condenses into larger particles whose momentum carries them into the wall and down the drain.  By making the walls suitably cold, 99+% of an aqueous stream can be diverted away from the evaporative zone.

 

 

 

The real benefit of Thermo-Split technology is that it can be controlled in a smooth analog fashion, by simply controlling a temperature. 

 

The temperature of the nebulization zone can be set from 0°C to 80°C, in 1°C increments.  This achieves split ratios of approximately 99% to 1%.  Unlike some ELSDs our splitter isn’t always on.  And unlike others, it isn’t constrained to the two choices of either on or off.  Instead, it can be on, off, or anything in between.  This patented technology was developed by SofTA Corporation, and is exclusive to our products.

 

Further, SofTA brings you an unprecedented level of electronic sophistication at truly affordable prices.
