An analyzer, and more specifically a sampler for exhaust-gas monitoring and analyzing apparatus, comprising a pipe for introducing clean air into the sampler, a sampling tube for drawing in gasses by suction, and an extracting tube for conducting the gas sample to an analyzer. The sampler is designed so that the admission of clean air thereto creates a sufficient suction effect for drawing in the gasses to be sampled.

DETAILED DESCRIPTION The present invention has for its object to eliminate the afore-described disadvantages of the prior art instruments and provide a sampler for analyzers which can effect dilution and synchronized suction with a constant dilution multiple and a high degree of efficiency.
The invention is characterized in that, in an analyzer using the open type sampling method, clean air is introduced into the sampler and, by dint of the injection effect, ejection effect or the like thereby created, the gases to be examined are drawn into the sampler by suction.
The manner in which the foregoing and other objects of this invention are accomplished will become more apparent from the following description, taken in connection with the accompanying drawings showing embodiments thereof.
