    摘要: Apparatus and methods for periodically testing emergency wash units which involve the use of a transparent splash containment device which is positioned over an emergency wash unit and optionally attached thereto. The transparent splash containment device diverts and directs water flow to the drain of the emergency wash unit. An alignment indicator including sighting marks is provided to determine the alignment of the water flow. The sighting marks are provided with grid scales which can be used to estimate the velocity of the water flow.

    摘要: An apparatus and method for directly applying a liquid sample matrix containing analytes and possible endogenous compounds to selected areas of a thin layer chromatographic sheet. The apparatus comprises a manifold made from an upper and lower filter block which are fastened together and supported on a support member. The thin layer chromatographic sheet is held between the upper and lower filter block. Samples are applied to the thin layer chromatographic sheet through aligned through-bores in the upper and lower filter block by connecting a syringe to the through-bores of the upper filter block. The method involves initially wetting areas of the thin layer chromatographic sheet where the sample is subsequently applied. Analytes retained on the thin layer chromatographic sheet are subsequently analyzed and may be further extracted from the thin layer chromatographic sheet for analysis.
