The present work examines the possibility to use homemade miniature
infrared (IR) sources in spectroscopic applications. Simple useful IR
applications were studied using IRsources made from in-expensive available
materials. Different liquids absorptions of broadband IR radiation were
compared. The effect of frying time on vegetable oil changing properties is
one of the applications described. Olive oil adulteration with in-expensive
vegetable oils such as corn oil was studied as a useful simple to perform
test. Industrially, the dependence of color dyes concentration on IR
absorption was also studied. These applications are discussed in view that
further improvement on such experiments could lead to the construction of
a portable handy useful testing system
