Overview of devices used for the HAG method. (a) Design of the TeCH-1 humidifier. This was assembled using the following components: (i) digital mass flow controllers, (ii) temperature-controlled air-bubbling bottle (2 l), (iii) air-cooling bottles (2 l and 500 ml), (iv) air-mixing area, (v) temperature and humidity sensor, (vi) original heat-exchanger unit, (vii) flexible transfer tube, (viii) refrigeration–heating circulator, (ix) coolant line, (x) temperature sensor, (xi) PC to control and monitor connected devices, and (xii) humid-air nozzle. (b) View of a diffractometer set up in the humidity-control position. (c) Enlarged view of the sample position for insertion of the humid-air nozzle. (d) Front view of the TeC-W workbench. |
