title: A low-cost differential fluorimeter for the detection and determination of LSD in illicit preparations.
abstract: The construction and use of a differential fluorimeter for rapid detection of LSD in confiscated material under field conditions is described. The apparatus is robust, electronics-free, compact and inexpensive. Adequate sensitivity is ensured by the high quantum yield of LSD fluorescence and a large degree of specificity is obtained by carrying-out two separate measurements: one in water and one in 1 M NaOH.
