This is mainly due to the elimination of additional band-broadening from tubes connecting the column and detector, ultimately, preserving the separation efficiency [58]. It should be taken into consideration that for effective on-column detection, accurate and narrow focusing of the light beam into...
Surveys conducted by NREL have shown that η is a complex function of storage capacity of water heater, type of water heater, age of water heater. No distributions are available for η in the current studies. Field data collected from NREL surveys50,51,52 show that the efficiency varies ...
