hey guy if u need more information u can search on internet I uploaded last few days
Your temperature profile, atmosphere, sample, etc are identical for both data sets - it eliminates uncertainty associated with differences in sample preparation, sampling, differing instruments and furnace materials, etc.
By employing STA, you get two experiments with the time and sample of one - this is very attractive for researchers into carbon allotropes and noble metals, where 1g of sample can be very expensive, and for those researchers who have difficult-to-prepare samples.
Because both data sets are collected on the same sample with the same ramp in the same furnace with the same crucibles under the same gas flow -i.e., because all possible confounders are controlled for - STA allows better correlation of time/heat flow and time/mass change phenomena in time-sensitive operations. It therefore would be my technique of choice for studying kinetic phenomena, like protein folding, among others.
