    • Gas testing apparatus comprises a gas chamber wherein a test body surrounded by a single turn electrical conductor is suspended by a metal strip in a non-uniform and non-symmetrical magnetic field which is formulated by especially shaped pole pieces which could, in one form, by permanent magnets. The test body is deflected from the initial position it takes when a reference gas is in the cell, by the admittance of a gas mixture of which is paramagnetic gas is one constituent. The deflection is sensed by an optical system comprising a light source, a mirror on the test body and a pair of photocells. The output of the photocells feeds an amplifier system, which in turn feeds the single turn coil by a current of an adequate value such that it stops the test body from moving from its initial position and hence is proportional to the partial pressure of the paramagnetic gas in the sample. The effect of the gas entering the chamber and influencing the test body is minimized by the especial design of the gas inlet, outlet and route within the chamber. The cell is rendered gas tight by hermetic and mechanical seals rather than by the use of adhesive.

    • A gas testing apparatus comprising a body (13, 14) defining a chamber (7), means (2, 3) for creating a magnetic field within the chamber in a first direction, a test body (20), means (19) for mounting the test body (20) for rotation about an axis parallel to the direction of the magnetic field, and gas inlet (9) and outlet (10) means for allowing gas flow through the chamber (7), characterised in that the gas inlet means (9) are arranged and disposed to supply gas to the chamber from two positions at opposite sides of the chamber whereby gas flow from each of the two positions will be parallel to the direction of the magnetic field but in opposition in order to minimize errors resulting from gas flow upon the test body. The chamber is of small volume i.e. less than 0.6 ml which enables the apparatus to be used for preliminary monitoring.
