A measuring cell (1) for the infrared analysis of fluids, in particular a measuring cell (1) having a permissible operating pressure of more than 20 bar and preferably more than 50 bar, has a flow channel (10) for the fluid formed between first and second elements (2, 4). Each element is transparent to infrared radiation at least in some sections. The infrared radiation can be radiated into the flow channel (10) by the first element (2) and can exit the flow channel (10) by the second element (4). The two elements (2, 4) are connected to each other in a fluid-tight and mechanically high-strength manner by a connecting layer (6) arranged between them and made of a glass-containing material, in particular a sintered glass-ceramic material. A measuring system (8) has that measuring cell (1). A method produces that measuring cell (1).
