Liquid samples are often collected and transported to a laboratory for purposes of conducting environmental analysis of the sample. Frequently, liquid samples are collected in a standardized container, such as a one liter glass sample bottle having a threaded top. Examples of apparatuses for use in testing liquid samples are described in U.S. Pat. Nos. 5,753,105 and 6,027,638.
One extraction technique is to filter the sample through a solid phase extraction (SPE) disk. As the sample filters through the SPE disk, the media within the SPE disk removes and concentrates the analytes of interest. Prior to testing, however, the SPE disk must be conditioned with a small volume of solvent. During processing, the sample bottle must be rinsed with solvent to ensure that potential analytes do not remain attached to the glass surface of the sample bottle, but are instead transferred to the disk. Improved devices and methods for facilitating preconditioning of the disk, transfer of the liquid sample onto the disk, and rinsing of the sample bottle would improve testing throughput by reducing the amount of manual labor necessary to extract a sample.
