Analysis of Column Bleeding Aiming to determine whether the samples containing LiPF6 salt cause excessive col- umn bleeding, an experiment was carried out by injecting a blank acetone sample (con- sidered as the baseline sample) before and after five injections of COES and SBS #2.

The overall uncertainty of the slope (URm) and intercept (URb) were calculated with Equation (5): URm = BR2 m + (t·SRm)2 URb = BR2 b + (t·SRb)2 (5) where t was the student’s multiplier for 95% confidence, which for N = 3, 5, and 10, was 4.303, 2.776, 2.365, 2.262 [23]. From the calibration curves, the concentration of each compound can be determined as x = (y − b)/m. Note that y is the measured peak area with a precision index (random 6 of 14 measurements. Thus, there is an overall uncertainty associated with the slope and the urements. Thus, there is an overall uncertainty associated with the slope and the intercept Figure 1.

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
