Method for qualitative analysis of foreign substance in body fluid e.g. saliva of human and animal e.g. dog, involves detecting presence of foreign substance in body fluid is detected, if reference spectrum lies within test spectrum
摘要
<p>The method involves irradiating body fluid with electromagnetic radiation in region of predetermined spectrum. A test medium is irradiated with radiation corresponding to sample spectrum so that spectrum of sample or test spectrum is stored in fluid test medium. The test spectrum stored in fluid test medium is compared with the reference spectrum. The presence of foreign substance in the body fluid is detected, if reference spectrum lies within the test spectrum. The viscous oil or aqueous suspension of water and silicon dioxide is used as test medium.</p>
