Abstract: A method for performing backup of computer specific information from a computer is disclosed. The method includes receiving, at a remote server, user authentication data obtainable from a user of the computer; in response to a positive authentication based on the user authentication data, the remote server establishing a communication channel between the computer and the remote server; authenticating, via the communication channel, the computer for use with the server; sending, via the communication channel, a computer specific information collect request from the server to the computer; collecting computer specific information at the computer; encrypting the computer specific information; and sending, via the communication channel, the encrypted computer specific information to the remote server.

Abstract: The present invention relates to a micro total analysis system comprising a spectroscope and a method of manufacturing such a system comprising a spectroscope in a one step process. More over the invention relates to a method of analyzing a sample in the system. The micro total analysis system comprising a spectroscope provided on a substrate and for measuring electromagnetic radiation and at least one microfluidic channel. The spectroscope comprises: a slab waveguide for guiding electromagnetic waves towards a diffraction grating dispersing the electromagnetic waves into their component wavelengths, and output means for receiving the deflected electromagnetic waves. At least a part of the microfluidic channel, the slab waveguide and the grating comprises the same main material, such as a polymer material.
