Abstract

A sensor element carrier for use in a mass-sensitive chemical sensor instrument comprises a base component and a lid component, the base component being adapted to receive, in use, a sensor, the signal generated by which depends on the mass of material adsorbed at a sensing surface thereof, the base component or the lid component having formed therein, in a recessed area, at least one channel for the ingress of sample fluid, the recessed area forming, in use and in conjunction with the sensing surface of the sensor, a sample chamber, the sensor being held, in use, between the base component and the lid component and the approach of the base component and lid component being limited on assembly of the sensor element by means of substantially rigid portions of each which come into abutment, thereby limiting the minimum height of the sample chamber for a given set of sensor, base and lid components.
