摘要： A device for measuring the total organic carbon content (TOC) of a sample fluid comprises a measuring cell (2) defining a volume (3) for containing a sample fluid and an excimer lamp (20) arranged to cause an oxidation reaction of the sample fluid by emitting radiation onto the sample fluid in the volume (3). A pair of electrodes is arranged to measure the conductivity of the sample fluid during the oxidation reaction and at least one temperature senor (31) is arranged on the measuring cell (2) to measure a temperature that is related to the sample fluid. The total organic carbon content (TOC) of the sample fluid is determined on the basis of the measured conductivity compensated by the temperature related to the sample fluid.

摘要： A biocidal fluid purification cap (2) for a fluid container (1), preferably one storing purified water for use in laboratory environments and especially purified water for cell culture and water for molecular biology. The purification cap (2) includes a cap body (3) including an engagement feature (20) for removably attaching the cap body (3) to a mating engagement feature on a spout of the fluid container (1) to hermetically close a spout opening, at least one LED (7a) adapted to emit light in the UV-C range, electronic circuitry (15) for driving the LED(s) (7a), and a power supply for the electronic circuitry (15). The LED(s) (7a) is/are arranged in said cap body (3) so as to be separated from the environment by an UV-transparent window (6) provided in the cap body (3) such that light emitted from said LED(s) (7a) enters the opening of the spout when the cap (2) is attached to the spout of the container (1).
