The present invention relates to a device for spectroscopic measurements, in particular X-ray diffraction (XRD), temperature-resolved second harmonic generation (TR-SHG) or infrared (IR) measurements, which prevents the formation of condensation (dew) or ice (frost) when carrying out spectroscopic measurements in sub-ambient temperature conditions and to a method of spectroscopic measurements with said device.

A device keeps an electrochemical cell under current and at operating temperature during an X-ray beam diffraction analysis of a first electrode, the cell comprising a solid electrolyte interposed between the electrodes. The device comprises: first and second interconnectors having contact faces contacting the electrodes, which allow a gas flow and exchange between the interconnectors and the electrodes. The contact face of the first interconnector allows an X-ray beam to pass to the first electrode. A thermal and atmospheric containment chamber has an inner cavity housing a stack formed from the cell between the interconnectors and a cover closing the cavity, provided with a window allowing X-rays to pass through, the first interconnector being intended to be arranged facing the cover. The contact face of each interconnector is a slotted element; slotted portions of the slotted element are uniformly arranged and form 30% to 80% of the element's surface area.

A heating device having a heating element patterned into a robust MEMs substrate, wherein the heating element is electrically isolated from a fluid reservoir or bulk conductive sample, but close enough in proximity to an imagable window/area having the fluid or sample thereon, such that the sample is heated through conduction. The heating device can be used in a microscope sample holder, e.g., for SEM, TEM, STEM, X-ray synchrotron, scanning probe microscopy, and optical microscopy.

A modular specimen holder (10) for high pressure freezing and/or X-ray crystallography of a specimen has a specimen holding element (100) and an extension element (200) connectable with and separable from each other; the specimen holding element (100) including a tubule (120) adapted to hold the specimen and a base element (110) adapted to hold the tubule (120), wherein a distance from a bottom of the base element (110) to a top of the tubule (120) is a first distance (d1); the extension element (200) being connectable with the base element (110), wherein, when the extension element (200) and the base element (110) are connected with each other, a second distance (d2) from a bottom of the extension element (200) to the top of the tubule (120) is larger than the first distance (d1).
