<p>An apparatus and method for analysing an amount of at least one component in a sample (21) by measuring a microwave signal (13) that has passed at least partially through the sample (21), the apparatus comprising: a microwave generator that generates a continuous linear sweeping microwave signal varying in frequency, a microwave transmitter (11), a microwave receiver (12), at least one microwave analyser that analyses phase shift and/or change in amplitude of a transmitted and received signal (13), a means (40) for determining a depth of the sample (21) and a processor that determines the amount of the component(s) in the sample (21) from the microwave analyser.</p> |
