ABSTRACT:
The invention provides a spectral analysis cell for the batch spectroscopic analysis of materials. The cell incorporates an integral trapping chamber whereby a sample may be trapped in any conventional manner in for example a sample trapping tube and delivered to the trapping chamber where it can be vaporized so as to deliver a vapor from the sample trapping tube to the interior of the cell.
