A gas sensing apparatus () comprises a gas sensor arranged to use light to sense presence of a gas; an optical element () arranged so that said light impinges thereon; and a thermoelectric heat pump () having a cold side () and a hot side (). The thermoelectric heat pump () is configured to transfer heat energy from said cold side () to said hot side () in response to a supply of electrical energy provided to the thermoelectric heat pump (). The hot side () of the thermoelectric heat pump () is in thermal contact with the optical element ().

Optical elements in gas sensors

The present invention comprises an apparatus and a method for mass analyses of an array of samples contained in distinct sample holders. The sample holders are placed on a plurality of sensors which preferably comprise an array of microbalances providing output signals comprising mass data on the array of samples.

Method and apparatus for mass analysis of samples

This invention relates to an optical displacement sensor element, e.g. for use in a pressure sensor or a microphone, comprising two essentially flat surfaces being separated by a cavity being defined by a spacer, the distance between the surfaces being variable thus providing a displacement sensitive Fabry-Perot interferometer. Both of said surfaces are at least partially reflective, and in that said first surface is provided with at least one optical detector, and one of surfaces being provided on an at least partially transparent material.
