The invention claimed is: 1. A sample chamber for a liquid, wherein the sample chamber is part of a sample carrier, at least part of the walls of the sample chamber being formed of a plastic material, wherein at least one part of the walls formed of the plastic material comprises a gas-absorbent and/or gas-permeable plastic, which is essentially degasified in at least one area and/or in which a predetermined gas is stored in soluble form in at least one area, and wherein the gas-absorbent and/or gas-permeable plastic provides for at least one of supplying the predetermined gas to the liquid and discharging gas from the liquid. 2. The sample chamber according to claim 1, wherein at least one further part in the interior of the sample chamber comprises a further gas-absorbent and/or gas-permeable plastic, which is essentially degasified in at least one area and/or in which a predetermined gas is stored in soluble form in at least one area. 3. The sample chamber according to claim 2, wherein the further gas-absorbent and/or gas-permeable plastic of the at least one further part in the interior of the sample chamber has an absorption coefficient and/or a diffusion constant that differs from that of the one gas-absorbent and/or gas-permeable plastic. 4. The sample chamber according to claim 1, wherein a predetermined amount of the gas is stored in soluble form. 5. The sample chamber according to claim 1, comprising at least two areas in which gases are stored in different amounts and/or concentrations. 6. The sample chamber according to claim 1, wherein a semipermeable or essentially impermeable material is arranged, particularly in detachable form, on at least one part of the surface of a gas-absorbent and/or gas-permeable plastic. 7. The sample chamber according to claim 1, wherein the sample carrier comprises a substrate in which the sample chamber is configured as a channel. 8. The sample chamber according to claim 7, wherein the channel has a ratio of cross-sectional circumference to cross-sectional area of about 10 to 1000, preferably of 20 to 250, most preferably of 50 to 100. 9. The sample chamber according to claim 7, wherein the substrate has a gas diffusion constant in a range of about 10−5 cm2/sec to about 10−9 cm2/sec, preferably of 10−7 cm2/sec to about 10−9 cm2/sec. 10. The sample chamber according to claim 9, wherein the substrate shows a water absorption in a range of about 0.001% to about 0.5%, preferably in a range of about 0.001% to about 0.01%. 11. The sample chamber according to claim 7, wherein the substrate shows a gas absorption potential of less than about 1 wt %, preferably between about 0.005 wt % and 0.1 wt %. 12. The sample chamber according to claim 7, wherein the sample carrier comprises at least one liquid reservoir and the channel is connected to the at least one liquid reservoir. 13. The sample chamber according to claim 12, wherein the at least one liquid reservoir is arranged on the substrate of the sample carrier. 14. The sample chamber according to claim 13, wherein the channel is incorporated into the surface of the substrate which is opposite to the at least one liquid reservoir. 15. The sample chamber according to claim 12, wherein the substrate and the at least one liquid reservoir are configured as one piece. 16. The sample chamber according to claim 1, wherein the sample carrier consists of plastic. 17. The sample chamber according to claim 1, wherein the sample carrier comprises integrated galvanic elements. 18. A method for treating a sample chamber for supplying and/or discharging a gas to a liquid, comprising the following steps: providing a sample chamber for a liquid, particularly according to claim 1, wherein at least one part in the interior of the sample chamber comprises a gas-absorbent and/or gas-permeable plastic; degasifying at least one area of the gas-absorbent and/or gas-permeable plastic and/or storing a predetermined gas in soluble form in at least one area of the gas-absorbent and/or gas-permeable plastic. 19. The method according to claim 18, wherein the step of degasifying and/or storing comprises introducing the sample chamber into a predetermined fluid environment. 20. The method according to claim 19, wherein a negative pressure or an overpressure is chosen for the predetermined fluid environment. 21. The method according to claim 19, wherein the introduction into a predetermined fluid environment takes place for a predetermined period. 22. The method according to claim 18, comprising the further step of arranging, particularly in detachable form, a semipermeable or essentially impermeable material on at least one part of the surface of the gas-absorbent and/or gas-permeable plastic. 23. The method according to claim 18, comprising the further step of a fluid-tight, particularly gas-tight, packing of the sample chamber. 24. The method according to claim 23, wherein the fluid-tight packing takes place in a predetermined fluid atmosphere. 25. The sample chamber according to claim 1, wherein the gas-absorbent and/or gas-permeable plastic provides for supplying and/or discharging the predetermined gas to and/or from a liquid. 26. A sample carrier comprising the sample chamber according to claim 1, wherein the sample carrier comprises a plastic substrate in which the sample chamber is formed, and wherein the plastic substrate is essentially degasified in at least one area and/or a predetermined gas is stored in soluble form in at least one area of the plastic substrate. 27. The sample carrier according to claim 26, wherein the gas-absorbent and/or gas-permeable plastic provides for supplying the predetermined gas to and/or discharging gas from the liquid.
