SAMPLING AND ANALYSING PROCEDURES AND APPARATUS

摘要

A sampling and analysing system sprays successive samples of analyte from a reservoir (10) onto a movable filter screen. A ''dose'' of labelled binding reagent (25) supplied from a container (26) is reacted with each sample and the sample is then analysed. The results of the analysis are supplied to a microprocessor (46) which computes the first and/or second order differentials from a series of repeated tests. Following analysis the samples may be rendered harmless e.g. by incineration.
