Abstract:
1. A sealable cell for measuring the spectrum of a liquid sample comprising a spectroscopic probe, which spectroscopic probe has a head comprising at least one optical fibre, a window, a reflecting mirror, a sample support located between the window and the mirror comprising an entrance passage and an exit passage; and which sealable cell also comprises a removable cap that accommodates at least the head of the probe such that the distance between the internal wall of the removable cap and the head of the spectroscopic probe is less than 0.4 mm; wherein the internal wall of the removable cap comprises one or more grooves disposed such that, when the spectroscopic probe is inserted into the cap, the entrance and exit passages of the sample support coincide with the one or more grooves and provide a path for fluid to flow from the base of the cap, and into and through the sample support.
