Abstract

An automated discrete fluid sample analyzer includes a sample preparation module. The sample preparation module includes a well configured to receive a sample deposited by a pipettor and a sample preparation device in fluid communication with the well. The fluid sample is transferred from the well to the sample preparation device, and the sample preparation device prepares the fluid sample. The pipettor then aspirates the prepared fluid sample. The prepared fluid sample may be transferred from the sample preparation device back to the well, and the pipettor aspirates the prepared fluid sample from the well. In one embodiment, the sample preparation device includes a receptacle having a catalyst disposed therein. The catalyst may include a noble metal catalyst, such as cadmium. In another embodiment, the sample preparation device includes an ultraviolet lamp configured to apply ultraviolet light to the fluid sample. In yet another embodiment, the sample preparation device includes a heater configured to heat the fluid sample. In another aspect, a fluid sample is agitated to place more of the fluid sample in contact with the catalyst.
