Our thin-film heating system for the gas holder discretely heats samples in the gas cell to > 1000ºC. Low-drift, high image stability and long lifetimes > 160 hours make the heating system not only robust, but allows tracking of the area of interest while imaging at high-magnification.
Heating is controlled via a custom-designed control box and software featuring closed-loop temperature control and four-point probe temperature sensing from an on-chip sensor, which is accurate enough to not only measure the sample temperature but to detect power changes small enough to be able to perform nano-calorimetry.
