Abstract

A simple, novel, and rapid method for the determination of density of microquantity liquids is described. The method may be employed in forensic science when liquids sent for analysis are available in microquantities (even up to 0.5 μL) for which density cannot be determined either by the capillary tube method, where accurate weighing is a problem, or by the other conventional methods such as specific gravity bottle method, Pyknometer method, or the Westphal-balance method. The retrieval of the sample is also possible in this method, which allows the analyst to carry out further analysis.
