Probe for liquid analysis

A probe for continuous liquid analysis, the probe comprising:

• at least one detector for measuring spectral properties of a liquid to be analyzed;
• and
• a liquid-tight housing for accommodating the at least one detector,
• wherein the at least one detector is housed in the liquid-tight housing,
• wherein at least one window is arranged in a wall of the liquid-tight housing, through which the at least one detector is configured to detect the spectral properties of the liquid,
• wherein the liquid-tight housing is connected to a flow channel, through which the liquid is configured to flow,
• wherein the at least one window is directed into the flow channel,
• wherein the flow channel is wound and comprises a helical shape forming a helix, and
• wherein the helical shape of the flow channel comprises a varying number of turns along an axis of the helix and a varying diameter.
