The invention relates to a sample-holding element () for a liquid sample for the simultaneous analysis of three or more chemico-physical parameters of the liquid by means of an analysis device. The sample-holding element () has a sample-holding chamber (), which can be filled with the liquid, wherein the sample-holding element () has at least three measurement points (N,) arranged adjacent to each other, which are distributed over the sample-holding chamber (), wherein two of the measurement points () are a photonic measurement point () and a refractive-index measurement point () and wherein the at least one further measurement point is selected from the group comprising at least a pH measurement point (), a conductivity measurement point () and a germ measurement point. The sample-holding element () is a planar element () that is double-walled at least in some sections and that has plates ('), which are arranged on each other in a plane-parallel manner and are connected to each other at the edges thereof at least in some sections, wherein the sample-holding chamber () is formed as a planar gap between the plates (&#x2032;) and the distance between the plates (&#x2032;) is just so large that the liquid sample can be subjected to the capillary effect between the double walls (&#x2032;). The measurement point () for measuring the refractive index has a refraction structure (&#x2033;) on one of the plates (&#x2032;) in a region predefined therefor. The invention further relates to an analysis device set having the sample-holding element () and having an analysis apparatus () and to a method for the simultaneous analysis of three or more chemico-physical parameters of the liquid.
