Microtechnique to Remove Particles from High Performance Liquid Chromatographic Samples

Abstract
A high speed (13,000 × G) microhematocrit centrifuge rapidly (1 min) removes particles from small (10-60 μL) volumes of sample solution prior to high performance liquid chromatographic analysis. The described technique, using glass capillary tubes, effectively cleans up aqueous biochemical solutions and/or concentrates of environmental samples. Advantages of the method are speed, small sample size, and moderate equipment cost.
